-* **images**
+* **Images**
   - PNG -- ~~use [LodePNG](lodev.org/lodepng), still in C~~ now written in nim
   - JPEG -- use [uJPEG (MicroJPEG) -- KeyJ's Small Baseline JPEG Decoder](http://keyj.emphy.de/nanojpeg), still in C
   - BMP -- use [EasyBMP](http://easybmp.sourceforge.net), already ported to nim, support 1bit, 4bit, 8bit, 16bit, 24bit, and 32bit images
   - beside transparency from original image(such as from PNG), you can adjust individual image transparency as easy as other elements in your document
 
-* **text and fonts**
-  - support TTF/TTC font subsetting -- use [Google sfntly](code.google.com/p/sfntly), ported(partially) to nim and modified
-  - you can easily tell the library to look for fonts in certain folder(s)
-  - you only need to ask for font family name and it's style, the library will try to find the right one for you(if avilable)
-  - text encoded in UTF-8 if you use TTF/TTC

   - 14 base font in PDF use Standard,MacRoman,WinAnsi encoding
   - TTF/TTC fonts can be written vertically if they have vertical metrics
 
 * **Path construction**
-  - straight segments, Bezier curves, elliptical arcs, roundrect
-  - join styles and miter limits
-  - dash patterns
-  - path clipping
-  - arbitrary path bounding box calculation(i use it to implement gradient too)
-  - construct path from mathematical function - taken from [ C# GraphDisplay](http://www.codeproject.com/Articles/58280/GraphDisplay-a-Bezier-based-control-for-graphing-f)
