Thanks, I'll experiment with this!

Sorry, I'm not sure what you mean by "compute (black) connected components". The only things that come to my mind are a flood fill tool, a fuzzy select magic wand tool, or morphology , and then I'm not sure what you are doing with them. Given a black and white image, produce a mask "image" of the ...

I am having trouble uploading the samples to my online repository so that I can link to them in the post. But in the meantime... Is there a way in IM to compute (black) connected components for a bitonal image?

The content of the images is a bit sensitive, so can I just post samples with the original borders but with the text area whited out?

I have a bunch of black and white TIFFs which are scans of old documents. Some of them have black borders of various sizes and locations: some around all 4 sides, some only on 1 or 2 sides, some borders thick, some thin. Is it possible to use ImageMagick to remove those? I tried "-trim" on a couple ...

My understanding, though I am no expert on this topic, is that if you are printing, the width and height does not matter. It is only the density in dpi. So you can easily just change the density to whatever suits you and it should be fine. We're not printing anything out. In fact, the work I am ...

If you can post a link to your input and output examples, perhaps we can test with it and find the appropriate commands Unfortunately, I can't provide any samples (the images are sensitive) Do you have to change the width and height of the image rather than just keeping it the same and just ...

I need to reprocess a bunch of old images. These are document images scanned at 400 dpi. What I need is something fairly simple: convert them to black and white (NOT grayscale) at 300 dpi and saving them in the TIFF format compressed as Group4, preserving quality as much as possible. Quality is not ...

I have a bunch of PDFs that I am trying to convert to various image formats, including PDF, using ImageMagick's convert that in turn is using GhostView to do the conversion (By the way, the reason I need PDF to PDF conversion is because the original docs are PDF with text behind and I need to ...
