I looked around and even photoshop only change image tint and add kisses stamps...
Today I was in need of something that would simple pick a UPS label image and resize the canvas to be a full Letter paper in 300dpi. ..because my printing app insists in always stretching the image to the whole size. resulting in a UPS label larger than the box.
I found nothing. Is this so? I don't want to start to write code and then learn I'm the only one not using some cool app.
