Hey, Given stamp size is lesser than passport.you can resize the image in GIMP without any quality loss . I think GIMP pops the option to select the quality when you try to save the image. Drag the slider to 100 % :)
If you are not gonna do it in a batch mode for many images;I would suggest GIMP is the easier path On Thu, Mar 18, 2010 at 9:42 PM, sanalkumar mr <[email protected]>wrote: > Does anybody think that the pixel values for a stamp size image given here > enough to get the quality image.?
