Hmmm... I think the original reason is that all the image decoders were written to produce either paletized (8bpp) or truecolor (24bpp) decoding, so it wasn't added. I see that you're interested in using the MWIMAGEHDRs built directly, and you're using 16bpp images. In this case, we'll need to add the 16bpp stuff into GdDrawImage. One of these days, I was planning on changing the whole structure to use the low-level screen driver blit routines to draw the image, which would fix this area in Microwindows, which is slow.

And also how about a structure that's suitable for DMA too? * jaster * _________________________________________________________________ 您可以在 MSN Hotmail 站点 http://www.hotmail.com/cn 免费收发电子邮件 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
