how to enlarge a binary image?

how to enlarge a binary image?

how to enlarge a binary image?

(OP)
I have problem with Character matching.
for example:
a given 16*14 binary image letter "A"
another given 18*13 binary image letter "A"
another 23*24 binary image letter "A"
to tell if they are the same, I need to enlarge them to the same size and then compare them. like all enlarge to 64*64.
any one know how to enlarge these images?
many thanks,
HJinfu Li

RE: how to enlarge a binary image?

I'm not quite sure what you mean by binary image (unless you mean two colour or something) but to physically change the size of the image go:

Image\Resize and then enter the pixel size in the top box.

If the letters are part of a larger image then it may be best to use the rectangle selector (or crop tool, etc) to cut a precise outline around the letter, just touching the right, left, top, bottom of the character - and then do your resize.

One easy way of comparing something like this is to do the resize and then put all three letters into a single image, but on seperate layers.  Then reduce the opacity of the top two layers and you will see where they match and where they don't!

If this made sense - good luck!
