Re: [Gramps-users] image or PDF

[Garry S. <see...@bi...>]

Yes I do not see the need to OCR and produce a true PDF document when I 
am just attaching an image to a citation. I see that I am adding an 
image as part of recording the details of a source/citation as further 
prove that the source exists and I don't see that I would need an 
editable document in that case. But, the discussion on OCR and producing 
true PDF documents has been interesting and has helped me understand 
more about PDF.

I have been using ImageMagick to extract images from PDF files and also 
to concatenate those images into a single JPG file. Here are my notes:

Use ImageMagick to save PDF pages as separate images

Open the PDF file from ImageMagick
Save as format JPG ie 1.jpg and set quality to 100 when asked
File - Next to view next page
Save as format JPG ie 2.jpg and set quality to 100 when asked
etc for rest of pages


 From the terminal concatenate images

$ montage -mode concatenate 1.jpg 2.jpg .....  result.jpg

use the option -tile <columns>x<rows> to control the layout to be 
applied. either side may be missing and montage will figure out how to 
meet the constraints.
ie $ montage -mode concatenate -tile 1x ..........
will concatenate the images in a single column
ie $ montage -mode concatenate -tile x1 ..........
will concatenate the images in a single row

Cheers.
