1.2.2

General changes:

• For GIMP 3.2 or later, you must install Batcher 1.2.2 or later. There was an issue preventing Batcher from working.
• Updated Dutch translation (thanks to @DiGro).

New features:

• You can now type or paste an output folder (beside choosing a folder from a file dialog or the dropdown). This makes it possible to specify a folder that does not exist (which is automatically created during processing).

Changes to actions and conditions:

• Levels, Curves: For GIMP 3.2 and later, presets saved with a mode other than linear (non-linear, perceptual) are now allowed.
• Brightness-Contrast, Levels, Curves: For GIMP 3.2 and later, these actions can now optionally be applied non-destructively. Blend mode and opacity can now also be adjusted.
• script-fu-unsharp-mask is no longer available as a custom action as it opens a new image in GIMP (even when running the procedure non-interactively) and is thus not usable within Batcher. The gegl:unsharp-mask filter can be used as a substitute (#138).

User interface changes:

• Batch Convert, Export Images, Export Layers: The default focus when opening the main dialog is now on the output folder entry.
• Moved labels for export settings to separate rows. This makes more room for the folder and filename entries (and particularly when translated labels are longer than their English counterparts). The labels have also been made clearer thanks to the additional space available.
• Slightly increased width for the file format entry to account for file extensions with more characters.
• If an action fails during the preview, an inline message is displayed instead of a modal dialog. This can vastly reduce frustration when a user adds and edits an action until the action no longer results in a failure (e.g. replacing default values such as unspecified files or adding coordinates for gimp-pencil). Additionally, this prevents message spam when an action fails when starting Batcher, which could result in Batcher getting unresponsive on some platforms (#133).

Bug fixes:

• Fixed several icons not changing when selecting a different icon theme in GIMP.
• Fixed a critical bug preventing Batcher from running on certain platforms for GIMP 3.2 or later.

1.2.1

• Updated translations: Dutch, German. Thanks to @DiGro and @ChrisLauinger77!
• In the rare event that a folder with the same name exists during export, the overwrite dialog will no longer display the Replace this file option as it was causing an error. While the file to be exported could in theory replace the folder by removing the folder and its contents, this would likely not be anticipated by the user, rendering this choice unsafe. If Apply this choice to all remaining files is checked or processing is performed non-interactively, the Rename new file is used instead (but only if a folder exists rather than a file).
• Fixed a crash when opening the custom action browser when certain custom layer effects are installed (#127).

1.2

This release includes quality-of-life improvements, particularly to the user interface, and resolves most issues reported since the previous version.

General changes:

• Added Brazilian Portuguese translation (thanks to @romrocha333).
• Added Korean translation (thanks to @Maguk-Bong).
• Added Polish translation (thanks to @jghosting764).
• Updated Dutch translation (thanks to @DiGro).
• Updated German translation (thanks to @ChrisLauinger77).
• Updated Japanese translation (thanks to @re-unknown).
• Removed filters (layer effects, GEGL operations) that were either redundant or had no effect. If you used these filters, they will be automatically removed (a warning message will appear, including a suggestion for an alternative filter if available).
• Batch Convert: Loaded images will now have their orientation automatically corrected based on the Exif metadata if present.
• Layers will now (again) be automatically merged before export to avoid exported images unexpectedly growing beyond their original boundaries. This can happen if layers contain filters (layer effects). You can switch this off by unchecking the new Merge visible layers and rasterize export option (#115).
• Changed the order of buttons in the dialog handling conflicting files for safety, with the most dangerous choice (replacing an existing file) now being the rightmost one.
• Adjusted installation instructions for macOS where the GIMP Preferences are located under a different menu.
• If you use the latest revision of Batcher (i.e. download the source code rather than the release package), you will no longer receive errors when updating the plug-in to the latest revision.

New features:

• Batch Convert: You can now adjust file format options when loading input files via the new Import Options... entry. Import options for file formats not recognized by Batcher (e.g. third-party file format plug-ins) cannot be adjusted and defaults will be used instead.
• Added support for new features introduced between GIMP 3.1.2 and 3.2-RC2, including new file import/export formats, vector layers and link layers.
• Batch Convert: You can now choose to export images to the same top-level folder as the input image using the new Match input folders option. You will be warned when choosing this option as you may permanently override the original images (#75).
• Batch Convert, Export Images, Export Layers: The most recently used output folders for processing are now saved (max. 5). Each Batcher menu keeps a separate list of recent folders (#77).
• Export Layers, Edit Layers: Replaced Apply opacity from group layers with a more generic Apply Group Layer Appearance, which now also applies layer effects, mode, masks and several other attributes (except color tags and locks) (#87).
• Added an export option named Rotate or flip image based on Exif metadata. This allows correcting the orientation of images with Exif metadata before export if you choose to not save Exif metadata, e.g. for the JPEG format (#91).
• Added filters (layer effects, GEGL operations) starting with gimp: as custom actions. For GIMP 3.1.4 and later, all of these filters are added. For GIMP 3.1.2 and below, only the following filters are added (others are unsupported or cause GIMP to crash): gimp:border, gimp:colorize, gimp:compose-crop, gimp:desaturate, gimp:flood, gimp:grow, gimp:posterize, gimp:scalar-multiply, gimp:semi-flatten, gimp:set-alpha, gimp:shrink, gimp:threshold, gimp:threshold-alpha (#85).
• If G'MIC is installed as a GIMP plug-in, a built-in action G'MIC Filter will now be available that simplifies applying a filter from G'MIC non-interactively (#98).
• If an action causes an error during processing or if a file does not exist, you may choose to skip the current image/layer and continue processing subsequent images/layers. This can be enabled permanently via Settings → Continue on Error. If you use Batcher non-interactively and you have a previous version of Batcher installed, you must remove Batcher, restart GIMP, install Batcher and restart GIMP again in order for the continue-on-error argument to be usable (#21).
• Batch Convert: You can now move around individual files or folders by dragging and dropping them anywhere within the input list, or by pressing Alt + Up/Down. This is useful if, for example, you intend to rename the images with a numbered sequence.
• Batch Convert: Files and folders can now be sorted by several criteria: original name, new name, creation date, modification date and file size. By default, sorting is performed in the ascending order, folders are always placed first and name-based sorting is case-sensitive. All these options can be switched off/on as needed.
• You can now view message logs recorded during processing via Settings → View Logs and save them to a file.

User interface changes:

• Export settings are now arranged vertically in the upper left part of the dialog. Clarified labels describing the settings.
• Batch Convert: Buttons for adding and removing files and folders are moved to the top and changed them to icons.
• The Show Original Names button shown in Batch Convert is now available for all plug-in procedures among the options at the top of the input list.
• Replaced labels for action and condition parameters and export options with shorter text, just like in filter/plug-in dialogs in GIMP. A label for a parameter now contains the parameter name instead of the (often lengthy) description. The description is now included in the parameter tooltip, if available.
• Adjusted the default size of the main dialog and its individual parts for each plug-in procedure.
• Adjusted widths of action/condition argument names to avoid extra empty vertical space (most notably in the Export Options dialog).
• Reduced the width of the quick dialogs given the vertical rearrangement of the export settings.
• The message area at the bottom now only spans the left part of the dialog to make more room for the preview. Also, the message area no longer takes empty space if no message is displayed.
• Error message dialogs issued by GIMP are now always redirected to the GIMP's error console (https://docs.gimp.org/en/gimp-errors-dialog.html). This avoids spamming the same dialog when attempting to close the dialog and focusing back on the Batcher main dialog (#107).
• Batch Convert: When loading a file fails (e.g. due to an unrecognized file format), the text below the preview now shows the message. You may still obtain warnings issued by GIMP (in the error console).
• Batch Convert: Each row now displays the full path of an input image/folder as a tooltip.
• Improved visual cues when reordering actions, conditions or array argument elements via drag-and-drop.
• A simple summary message indicating the number of successfully processed images/layers is now displayed after the processing.
• Marked names of common layer effect arguments as translatable.
• The Export Options dialog is now closed before the start of processing.
• Replaced the widget for choosing output folder with a custom widget. The folders previously available (such as the home user folder, disk drives, ...) are no longer available.
• Adjusted wording and icon in the dialog handling conflicting files for clarity.
• An info icon is now displayed for skipped actions for clarity (e.g. actions trying to use foreground layers when there are none).
• Changes to the custom action browser:
  • Adjusted the default width of the dialog and its individual parts.
  • Merged the Menu Name column into the Name column. The browser now only displays the menu name if available, or the internal name otherwise. If the menu name is available, the internal name is displayed for the currently selected action with a smaller font.
  • You can now search by multiple words. At least one matching word will yield a match. Whitespace characters are no longer considered when finding search results.
  • When searching and the first match is under a collapsed category, that category is expanded automatically.
  • Categories with no matching search results are now hidden.
  • Several minor UI tweaks (such as different expander arrow icons to be consistent with the GIMP plug-in browser, or the Add button being insensitive when no action is selected).
  • Optimized search and expanding/collapsing categories.
  • The expanded/collapsed state of each category is now preserved when saving/loading settings.
  • For GIMP 3.1.2 and below, moved the following filters under the Other category as there are alternative filters/plug-ins available in GIMP: gegl:gray, gegl:posterize, gegl:threshold, gegl:wavelet-blur.
  • For GIMP 3.1.4 and above, moved the following filters under the Other category as there are alternative filters available in GIMP: gegl:brightness-contrast, gegl:levels. These are not removed in case they are being used.

Changes to actions and conditions:

• For filters that can only be applied destructively, Merge filter will always be checked and cannot be changed (#43).
• Actions and conditions are now organized in submenus and have a fixed position in the submenus for easier navigation.
• Actions and conditions will now display their description (if available) as a tooltip.
• Changed names of built-in actions and conditions to title case for consistency with GIMP tools, plug-ins and filters.
• Color Correction:
  • Split into separate actions and organized under the Color menu.
  • Reduced the range of allowed brightness and contrast values. The value range is now scaled to -127 to 127 for consistency with GIMP.
  • For GIMP 3.1.4 and later, you can choose a different filter responsible for adjusting brightness and contrast values. The default filter for GIMP 3.1.4 and later is equivalent to the Brightness-Contrast tool in GIMP. For earlier versions, gegl:brightness-contrast is the default (and the only option).
  • GIMP presets for l...

1.1.1

• Fixed the former Resize to layer size action being incorrectly updated when upgrading Batcher to 1.1.

1.1

General changes:

• Added Japanese translation (thanks to @re-unknown).
• Added Spanish translation (thanks to @ikizgz).
• Updated Dutch translation (thanks to @DiGro).
• "Procedures" are now referred to as "actions". "Action" is more intuitive.
• "Constraints" are now referred to as "conditions". "Condition" is more intuitive.
• In Edit Layers, actions are no longer applied to copies of group layers (inserted as regular layers), but rather to their original counterparts. This was previously done to avoid plug-ins failing on group layers. However, many plug-ins in GIMP 3 were removed in place of layer effects (filters) achieving the same result, the latter of which can be applied on group layers. Thus, there is little need to work on group layer copies now. This change also fixes a bug where creating a layer copy would create extra entries in the undo history.

New features:

• New major feature: Batch-editing and saving images opened in GIMP as XCF, available in File -> Edit and Save Images and File -> Edit and Save Images (Quick). Existing GIMP images are saved to their respective locations, while new images are saved to the specified output folder.
• Added a new action named Color correction. You can adjust brightness, contrast, or apply levels or curves from a saved preset file. Both GIMP and Photoshop formats (.alv, .acv) for preset files are supported.
• Added a new action named Crop. You may crop the entire image or a layer in a variety of ways - cropping from edges, from a fixed position (top left, center, ...), to the specified aspect ratio, to the specified area (bounding box), or to remove empty borders.
• Replaced Resize to layer size with a more generic action named Resize canvas that allows several more resize modes (add borders, resize from position/area, resize to aspect ratio, resize to image size) and filling the newly added space with a color.
• Added a new action named Rotate and flip. You may rotate the entire image or a layer, along with several options such as the angle, or whether to rotate from the center or from a fixed point.
• Added a new condition named XCF (native GIMP) file that applies only to opened images associated with a native XCF file.
• Added a new condition named Not XCF (native GIMP) file acting as the inverse of XCF (native GIMP) file.

Changes to the user interface:

• Batch Convert: Changed Add Files... and Add Folders... to menu entries displayed when clicking the new Add... button. Likewise, Remove Selected and Remove All were moved under the new Remove... button.
• If the output directory no longer exists and Batcher is started, the output directory is set to the Pictures folder (or another folder that is guaranteed to exist). Previously, "(None)" was displayed, which was confusing.
• Increased the default size of the main dialog.
• Increased the default size of the preview. For historical reasons, the preview was kept small to be consistent with the GIMP's Export menu. However, given that Batcher allows applying arbitrary filters, inspecting changes in a small preview can be difficult and the user is forced to manually resize the preview (this also assumes that the user is aware the preview size can be changed).

Changes to actions and conditions:

• You can now apply actions to layers inserted by actions other than Insert background or Insert foreground, e.g. gimp-text-font (which renders a text layer), by selecting Layer Below (Background) or Layer Above (Foreground) (depending on whether the layer is inserted before or after the current layer).
• Renamed Background Layer to Layer Below (Background) and Foreground Layer to Layer Above (Foreground) to make this feature more discoverable as per the change above.
• Scale:
  • Merged Object to scale, Image and Layer to a single widget.
  • Units for width and height are moved next to the width and height widgets, respectively.
  • More units beside pixels and percentages can be chosen from (the same ones available in GIMP). These units are recalculated automatically.
  • Switching between pixels, percentages and other units will now restore the last value for that unit.
  • Merged Scale to fit, Keep aspect ratio and Dimension to keep to a single widget.
  • Added a new option Fit with padding under Aspect ratio that fits the image/layer to the specified dimensions and fills the empty space with the specified color (transparent by default).
  • Added a new option to change the image resolution.
• Align and offset:
  • Merged Another layer to align layers with into Object to align layers with.
  • Units for x- and y-offsets are moved next to the x- and y-offset widgets, respectively.
  • More units beside pixels and percentages can be chosen from (the same ones available in GIMP). These units are recalculated automatically.
• Rename: Removed the Rename images option in Export Images due to being redundant there.
• Matching text...: Added Does not start with text, Does not contain text and Does not end with text options.
• Edit Layers: The Selected in GIMP condition is now added on the first run/after reset.
• File arguments can now be cleared (set to an empty value). This is useful if an action allows omitting a file.

Bug fixes:

• Fixed preview and export of images with linear precision.
• Fixed the Scale action always considering the layer size when keeping aspect ratio or scaling to fit dimensions.
• Fixed the output folder button not filling the empty space when increasing the dialog width.
• Fixed warnings when exporting layers or images opened in GIMP that are not native GIMP images (XCF).
• Fixed a crash when adding a layer effect (GEGL operation) whose name contains / or . (#74).
• Fixed URL to the Batcher user guide via the Help button (#73).
• Fixed a crash when running Batch Convert non-interactively if the path to the text files containing inputs is not specified.

1.0.2

• Added Dutch translation (thanks to @DiGro).
• Updated German translation (thanks to @ChrisLauinger77).
• Fixed a crash when saving Export/Also export as... procedures (#37).
• Fixed a crash on startup if the Pictures user folder as the default folder is not available (#41).
• Fixed several typos in translatable strings.
• Updated installation instructions for Flatpak users.

1.0.1

• Updated German translation (thanks to @ChrisLauinger77).
• Fixed a bug that caused the same custom procedure added multiple times to be saved only once.

1.0

User interface changes:

• Batch Convert: If a file is not found, an appropriate label will be displayed below the preview rather than a popup.
• Native file dialogs are displayed, if possible, when opening/saving settings files or adding files/folders for Batch Convert.

Bug fixes:

• Fixed update of settings from 1.0-RC1 to later versions.

1.0-RC4

New major feature: Export of images opened in GIMP. You can perform image export via File → Export Images... or File → Export Images (Quick). As with other plug-in procedures, you may make use of procedures and constraints (such as "only images with unsaved changes"). Note that this feature exports images to another file format, i.e. it does not mass-save XCF images in their original locations.

General changes:

• When exporting each image/layer individually, layers are no longer automatically merged into one. This allows preserving layers when exporting to a multi-layer format such as PSD.
• Batch Convert is now guaranteed to be accessible in GIMP even if no image is opened.

Changes to procedures:

• The Rename procedure is now automatically renamed based on the specified pattern (e.g. Rename to "image[001]").

Bug fixes:

• Fixed a crash on startup for macOS installation packages.
• Fixed a crash in non-interactive mode if the settings file is not specified.
• Fixed a warning message displayed when exporting or editing layers of an imported (i.e. non-XCF) image.
• Fixed console warnings when opening the custom procedure browser.

1.0-RC3

• Fixed Batcher not working when installed in a folder with elevated privileges (e.g. the system plug-ins folder containing built-in GIMP plug-ins instead of the user-specific plug-ins folder).
