I'm a writing a program for displaying TIFF files on a EGA. Currently all the TIFF stuff is working OK (I'm able to display on a Hercules) and can display also in the EGA using TC putpixel. However it is very slow to display pixel at a time. What I want to do now is to display the file using TC putimage, and my problem is to create a putimage bitmap in the correct format. For example, with a Hercules each pixel is 1 bit in the bitmap, but in the EGA each pixel has 4 bits in the bitmap. What I want do know is which are the bits patterns for displaying a WHITE pixel and a BLACK pixel. Any one can help me with this problem ? any suggestions ? Please reply by e-mail.
