[comp.windows.x] Bitmap_pad parameter in XCreateImage

cristy@eplrx7.uucp (John Cristy) (02/23/90)

  Should the bitmap_pad parameter in the XCreateImage routine match the 
  value of XBitmapPad(display)?  On an Ardent Titan, using a PseudoColor 
  visual, if the bitmap_pad parameter is 8 instead of 32 (as returned 
  from XBitmapPad(display), 3 pixels at the end of each scanline have random 
  values (image is 512x512).  If I change the bitmap pad to 32, the last 
  few bytes of the scanline are black.
   
  I would perfer to leave the bitmap pad at 8 so when I create the image
  I do not need to take into account the extra padding at the end of
  each scanline (extra code).  But if it is recommended to make the
  bitmap_pad parameter the same as XBitmapPad(display) I will write the
  extra code required.

  Thanks in adabance for your help.
