Re: PNG malfomerd: can you find differences ?

I know snibgo, I use PHP GD to reconstruct PNG from a base64 string. The string in http should be the same passed to PHP functions.... Is there any way to analize file 1.png and 2.png ? OR Can IM decode this base64 txt and return image ? http://gazzettannunci.gazzettadimantova.it/PRJ/storage/01_base...

Re: Montage: files with different dimension, but right proportions

Re: Montage: files with different dimension, but right proportions

Hello,
take some time to learn how assemble some models, but users are happy.

Another request, how spacing images using fmw42 syntax ?
Try to add:

Code: Select all

 -bordercolor "#ffffff" -border 6
but I want to border all images and then assemble together

Thank you for any help
