Picture Format

[morlok]

When I try Load_PICTURE with the 'masm32.bmp' from media dir, it work fine. But when i put my own picture (24 bits) the image don't appears on the screen. Load_Picture return TRUE.
What can be the problem?



thanks

Another thing, if i rename the attached jpg, and put it the name 'masm32.jpg', and place it into framework dir 'Media', then the program 'Display_JPG.exe' don't work.

thanks for your answer. and your FrameWork of couse.

Textures' sizes need to be power of 2 (eg. 1024x1024, 512x512 etc).

[morlok]

Ok, works fine.

Thanks
