Supported Image File Formats/en
Although expecco supports a wide range of bitmap image formats, some seldom used formats are not supported, or only supported with limitations.
GIF
reading and writing of 8 bit/pixel palette images is supported. Other images should be converted to 8bpp before writing. Tiled images with multiple palettes are not supported.
JPEG
reading and writing of 24bit/pixel is supported. Expecco uses the libjpg library, so any format supported by that (standard) library will also be supported by expecco.
PNG
(see http://www.schaik.com/pngsuite/pngsuite.html)
- Grayscale + alpha: reading unsupported (as of 2.11)
- 16bit RGB + alpha: incorrect display
