  How to generate GIF image with properties like Horizontal Resolution 96 dpi Vertical Resolution 9...

  Aug 05, 2011 10:03 AM|LINK

  Hi All
  
  I have one doc file i want to convert that .doc file to .GIF file with the following properties
  
  Non-Interlaced GIF (CompuServe) 89a
  2 colors (1-bit)
  Horizontal Resolution 96 dpi
  Vertical Resolution 96 dpi
  Bit depth 8
  
  below is the code that i have used. I am converting doc file to .tiff first and then tiff to .gif file. This code is working fine on windows 7 but not on XP. Also it setting Horizontal and Vertical Resolution to 200 dpi, although I am setting the resolution in code to 96 dpi.
  
  Can anybody help me out...
