how to crop till text edge and later add 10bp margin all around

[sant527]

I was deperately looking for such an appliction.

i found it at https://tex.stackexchange.com/a/447756.

I was looking for this kind of application

I have a pdf with the margins are not same on each side.
I have a pdf after cropping it i want to have 10dp all around croped/cliped text.

How to do it.

In pdfcrop we do
pdfcrop -m 10 filename.pdf output.pdf

ANSWER: (this worked)

pdf-crop-margins -v -a -6 -p 0 input.pdf

Thanks for the report. To get 10bp all around the command would be:

pdf-crop-margins -a -10 -p 0 input.pdf

There are 72bp/inch, which is the unit PDF files use and which pdfCropMargins uses. You wrote that you want 10dp, but that conversion depends on the dpi density value of a given device. The pdfcrop program uses bp, too. The Pillow bounding-box algorithm can differ slightly from the GhostScript one (which pdfcrop uses), so a little adjustment might still be needed for similar results.

Assuming 10bp, the equivalent of the pdfcrop command above, with the output file specified and in verbose mode, would be:

pdf-crop-margins -v -a -10 -p 0 input.pdf -o output.pdf

I've added an example in the help page of adding a constant amount past the bounding boxes. With regard to the tex.stackexchange link, I added a new feature that the threshold value can now be negative. This inverts the test of foreground vs. background, for images with dark backgrounds and light foregrounds.
