Quote:I've got all 35 into the latest version of gimp. ...cropped one. couldn't find how to crop all simultaneously.
Are the 35 loaded as layers ? If they are, the crop tool will crop the whole image. Make sure the crop tool options Current layer only is OFF and Delete cropped pixels is ON.
Quote:I do have a 'batch image manipulation' menu choice there but I was unable to figure out how to use it to do these things.
You have BIMP plugin? Too much time on my hands today
IMHO it is faster to edit each layer (or image) by hand, however, as an example.Open the PDF (I found a single PDF for that manual) one way or another, as layers. Make sure ppi is 300.
Crop the image.
Export the cropped image layers as individual images. There are plugins for this, if you do not already have one try Ofnuts plugin https://sourceforge.net/projects/gimp-to...p/download
In BIMP
Open the 35 images. BIMP does not open / save PDF hence the above process.
Add three procedures
1. color correction with brightness about 0.2 and contrast 0.04
2. other gimp procedure - gimp-level-auto
3. other gimp procedure - erode with settings 1 0 1 15 255 0
Set up an output folder and apply BIMP.
For a new PDF.
Open the corrected images in GIMP 'Open as layers'
Export as a PDF with 'Layers As Pages' enabled
As a video example, 6 minutes of tedium. https://youtu.be/Y5KAB822M9s
Remember I remarked that Gimp makes big PDF's - This one no different. 33 MB file size. However using LibreOffice and assembling the images in separate pages, got one down to 11 MB. https://www.dropbox.com/s/u749veg1bz7q7r...l.pdf?dl=0
All it takes is much perseverance and practice.
