I'm not clear on the question. To get all image pairs processed, won't they have to be all looped over one way or another?

I'm performing this operation: composite "Original.png" "ToRemove.png" -compose dst_out "Destination.png" Wouldn't it be: ? composite "ToRemove.png" "Original.png" -compose dst_out "Destination.png" And I don't produce that problem with th...

I guess a lesson to Halle and the rest of us to avoid superlatives in our subject lines.

I don't immediately see anything helpful. No, a setting after should not affect a command from before. Settings before, even ones intended for another operation (even when in parentheses) will. Is the black frame the correct size? It would be helpful if you could provide the shortest example that ha...

Your difference image could take many forms, most simply white for pixel is different and black is pixel is same (or the other way around). In any case, any image can be saved in several formats, including text. See:
http://www.imagemagick.org/Usage/files/#txt

Is that like what you need?

Sure you could do this with ImageMagick. The output could be an image or text (but probably require some post-processing on your part to get it in the format you require).

And is it possible to generate an alpha channel for this image where all fully transparent pixels are black and all solid pixels are white? It should be possible that semi transparent pixels should get gray in the alpha channel. The more a pixel is transparent in the image the darker the gray level...

My apologies for assuming you wanted to keep the 'blocky' pixelated look. Using a separate filter for alpha: convert in.png -filter your_color_filter -resize 200% rgb.png convert in.png -channel A -separate -filter your_alpha_filter -resize 200% alpha.png convert rgb.png -channel RGB -separate alpha...

You could generate a label: of a specified -size, or create a label: and then -crop it. Do you know how you would handle too much text if you could detect it overflowing? Yes, you can determine the width of the new label: canvas.

-distort is powerful, but complex enough to have its own examples page . It shines most when combining two resample operations, such as resizing and rotating in a single step. It handles many other needs too, but I don't yet understand why it would be worth the headache for a simple resize. If you ...

Disgracefully, I am limited in my Linux knowledge. On Windows, I use Bullzip's PDF Printer . Installed as a print driver, it converts a print job to a file. Despite the name, several save formats are supported. It supports command-line and COM interfaces, but I have yet to personally use those. Beca...

I would certainly take NicolasRobidoux or Anthony's advice over mine.

I have never done this personally, but I saw some examples over at:
ImageMagick v6 Examples > Text to Image Handling > Text - Formatted Pages of Text

For alternatives: Are you on Windows? Require a command-line interface?

I see how to convert between RGB and Lab using -colorspace . I eventually figured out how to go between color profiles (Adobe RGB, ProPhoto RGB, Gray Gamma 2.2, etc.) using -profile . I can't find any way to go from a color -profile to Lab color . This can be very useful when resampling, sharpening,...

You seem very determined, so here is more: The easiest and most accurate way to compare two results: Put them exactly on top of each other and switch between. This lets your eye catch the subtle differences. I find it aids comparing, and learning too. (Does anyone know how to create an image file wi...
