I have some drawings I made with an Intuos tablet. All of these drawings are 25x35 or so. The color of each pixel was very carefully selected. They're kind of like 'miniatures.'
I need to resize these. But I ran into problems. The images get dithered, and if I make them huge, blurred.
Here is the image at normal size. It happens to be dithered, but this is not visible.
I used the following two imagemagic commands, but they both produced blurring:
convert -resize 400% image.xcf image-2.jpg convert -adaptive-resize 400% image.xcf image-2.jpg
