This is a question about Turbo Pascal. I just found out that SetRGBpalette() function couldn't change the RGB values for 6, 8-15 slots in VGA color palette although I still could use 1-5 and 7. Does anyone have simular experience or some hints of what is going on?

I just wrote a program that played with all 256 color palette registers, and they all work! What kind of VGA do you have? I have a Paradise card and I'm using the svga256 driver in 640x480x256 mode. -- David Conrad | K9 hits the mountain nymph.--More-- dave@ddmi.com | The mountain nymph steals a cursed +0 chain mail. -- = CAT-TALK Conferencing Network, Computer Conferencing and File Archive = - 1-313-343-0800, 300/1200/2400/9600 baud, 8/N/1.

I >have a Paradise card and I'm using the svga256 driver in 640x480x256 mode. I think the mode makes the difference. Note that the colors mentioned as working properly in the original post are those whose default 16-64 mapping don't have the high bit. I had a similar problem at one point and solved it by simply setting the 16-64 map to map to straight 0 through 15 and then doing the 64-2^18 remapping. >-- >David Conrad | K9 hits the mountain nymph.--More-- >dave@ddmi.com | The mountain nymph steals a cursed +0 chain mail. >-- >= CAT-TALK Conferencing Network, Computer Conferencing and File Archive = >- 1-313-343-0800, 300/1200/2400/9600 baud, 8/N/1.
