Description of the bug

When importing a Gerber file generated using KiCad 9, the gerber's vertical axis is clipped when importing using "Tools > PCB Exposure". This causes some of the PCB Artwork/geometry to be missing.

How to reproduce

Repro Steps:

For reference, the KiCad 9 project used for this can be found here

Settings for the gerber export/plot were as follows

1. Download gerber.zip.
2. Extract the two Gerber files, "BIOS Adapter-F_Cu.gbr" and "BIOS Adapter-PTH.drl" from gerber.zip.
3. Use Chitubox to generate a dummy sliced file and save as *.goo format. For convenience, feel free to use PCB.zip.
4. Open UVTools and open the extracted PCB.goo file (File > Open > PCB.goo).
5. Navigate to Tools > PCB Exposure.
6. Under the PCB exposure section in the dialog popup, select "Add" and select both "BIOS Adapter-F_Cu.gbr" and "BIOS Adapter-PTH.drl".
7. Select "BIOS Adapter-F_Cu.gbr" from the file preview list under the "PCB exposure pane" within the currently open dialog.
8. Notice that the preview pane displays the Gerber file with a chunk of the vertical axis clipped/missing.
9. Select "Create one layer per gerber file".
10. Click the "PCB exposure" button at the bottom of the dialog.
11. Notice that the imported Gerber image layer is missing some of the vertical axis.

Anyway, just as an aside, I really love this feature of UVTools and am glad it exists, you did an excellent job with it.

Can you highlight wheres the missing part? I can't find the difference between your red and white image.

EDIT: I think you mean the lacking of bottom two align pins which are cut from your preview?
If so, this is the problem of lack of space, see #1009

You can just move the design to 0,0 origin or offset in UVtools:

Oh interesting, that does make sense, brigado Tiago!
