What command are you using for the merge? Any operation that involves two input files will copy the profile and other data from only one of the input files. (And it shouldn't change either input file, unless you use mogrify.)

It might be a good thing if the documentation http://www.imagemagick.org/script/comma ... hp?#affine mentioned this additional pixel border.

"identify -verbose" shows output.png from the first command carries a huge comment, which seems to be the numbers behind the graph, a written form of the histogram. output.png also has a comment, but now it seems to be the histogram of the histogram image, which is (of course) much simpler...

Yes, that's it. That's why you need to find commonalities between source images. "compare" will find "similar" matches, hence my cut-off at 66% will finds lines that are shorter than 10 pixels, or are slightly diagonal, etc. Reduce that number to far, and you will get false posit...

For this particular image, moo.jpg, IM can readily find the horiontal lines. Use a search pattern (say) 10 pixels wide, and six high. Make lines 0, 1, 4 and 5 white; lines 2 and 3 black. compare -metric RMSE moo.jpg search.png found.png Threshold found.jpg [edit: I mean found.png] about 66%, and it ...

You'd have to examine a few examples to determine commonality. For example: - Trim off surrounding white space. - Is the date/time always in approximately the same position? Then crop everthing else away. - Are the lines usually/always thicker than the letters? Then morphology erode will erode them ...

Incidentally, I don't get that problem on some trial images with IM 6.6.0-8 on Windows7. Can you post mouse.png? What IM version are you on?

Very strange. You might want to post this in the bugs forum: viewforum.php?f=3

Meanwhile, you might try "-rotate 90".

You are asking a Visual Basic question on an ImageMagick forum. I don't know the answer, but an internet search turns up many possibilities.

Your command works for me on Windows 7, IM 6.6.0-8. Can you post the input image? What IM version are you on?

If org.jpg has an embedded profile, your command should create a monochrome version.

If it doesn't, you should add the appropriate profile first, eg:

convert org.jpg -profile sRGB_v4_ICC_preference.icc -profile bw.icm org_bw.jpg

Can't you get the classnotes eletronically? What decade are we living in? If the paragraphs are divided by blank lines, you could use "compare" to find the gaps. But you would have to handle paragraphs that spanned pages. Unless you have a large volume to do, I'd think Gimp cut and paste w...

If you know the coordinates of the ends, IM could paint quickly over them. Finding those coordinates in the general case wouldn't be trivial.

Inkscape creates SVG or PNG, but nothing else. Printers use different inks and papers. The conversion to CMYK should take account of this. (One paper/ink combination might need less magenta ink and more black to get the same result as another paper/ink combination.) The information about these requi...

As magick hints, to ensure "the coloring comes out as it should", you MUST know the profile of the output devices. Ask your printer for the profile, which will be a .icc or .icm file.
