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
- TRNS chunk with alpha values (only on-off masks)
BMP
most formats are supported in reading; 1,4,8 and 24 bit files can be written.
TIFF
most formats are supported in reading. 1, 4, 8 and 24 bit files can be written
XBM
both reading and writing
XPM
some restrictions apply (to be documented)
Other Formats
Support for other formats, which are more or less of historic interest, can be made available upon request and at some extra charge: XWN, Targa, Sun-Raster, PICT, PCX, PBM, OSX-Icon, IrisRGB. Also, subset of the AVI and FLI formats can be provided if there is a need.
