This is all rather new for me and I hope this is the right place to ask this question but it seems that opening a Pdf file should be very routine. However this is not working for me, I have a 5.3 MB v 1.4 pdf file that has 1200 ppi resolution and unless I reduce the Resolution Import setting to 737 it gives me the attached warning. Why when it does import at 737 ppi the file "Size in memory:" is 5.6 GB see attached Image Properties, then when saved as Pdf it is 220 MB, this should be less than the original 5.3 MB with lower resolution?

How do I import at full 1200 ppi resolution and save the file again as a single layer PDF in full resolution at a reasonable file size.

Many Thanks, Clipper

You are importing a PDF file. That's not an image format, but a prepress format containing text, drawing elements, and bitmap graphics.

GIMP cannot work on the text and the drawing elements as those. As GIMP is a bitmap editor, the PDF importer make bitmaps from *anything* in your PDF file. This is why the file is so big opened in GIMP and stays big when you export it as PDF. It's all one big bitmap instead of text and drawing elements.

If you want to edit PDFs with a low amount of bitmap graphics, or care about text/drawing content stay as it is, GIMP is not the right tool for you. If you want to work on the bitmaps included in a PDF, you have to rip them from the PDF first, edit in GIMP, then put back the edited bitmap into the PDF. Adobe Acrobat can do this, but there are a lot of other options. Google for "replace image in pdf".

Kind regards

GIMP is an image editor; PDF files aren't images. You might as well say that opening a gramaphone recording of a piano sonata by Beethoven should be very straightforward in GIMP :-)

You can try opening your file in sk1 or in inkscape.

Best would be if you said exactly what you're trying to do, so people can give appropriate advice instead of guessing.

Best,

Liam

Sorry, You are right I should have explained the problem not my frustration. My PDF file is a collection of layered text, line work, .jpg, and transparent .png images. My local printer says he cannot print it and it needs to be flattened.

Open the file in a PDF reader, then export it to a simpler PDF level, flattening out all the forms, javascript and fancy features it might have.

You can also install a "Print to PDF" printer driver on your machine. This does exactly this: Creating a printable PDF from any PDF or any other content you might want to print.

Sorry not being more specific, but you hadn't been either (about OS, willingneess to pay $$$ etc.)

Kind regards

Send the PDF back to whoever made it and tell them to send you a PDF "without layers".

If you can't get the PDF re-output as a "flat" PDF, your simplest route may be to sign up for one month of Adobe Acrobat in the cloud and flatten it yourself. Heresy! I know, but getting it done right for your printer is the object here, right?

Sorry, You are right I should have explained the problem not my frustration. My
PDF file is a collection of layered text, line work, .jpg, and transparent .png images. My local printer says he cannot print it and it needs to be flattened. I just started using GIMP so I though if I could load the file then
maybe I could do something with it so my printer could print it for me. Only
one printer in town so I am kind of stuck.

Many Thanks, Clipper

Thanks Jan,

I have Adobe Reader but do not see an export option, just Save as... but not sure how to make that work.

I am running windows 10 and have a very limited budget on this volunteer project.

Was looking at PDF print drivers on-line. This seems like a simple solution. Do you have any recommendations for one that will allow me to use a custom paper size of 26" X 38" and maintain 1200 dpi. Are you familiar with PDF 995, will that work?

Printing to pdf may indeed be a good solution. I can't give you good advice on which "PDF printer driver" to install because I don't use Windows. It is much easier on Linux where such features are default.

If you don't manage this way, I could also advise Scribus, which has a good support for importing, editing and exporting PDF for printing: https://www.scribus.net/
Note: use the development release (1.5.x) and not the stable release. The different in PDF support is huge.

Now for your usage, Scribus may be a little overdoing it. It does not look like you are looking for that much. But well that's still a good Free Software to know about, if ever you had more needs for making documents for the printer.

Many Thanks Clipper

I can export by default, on Win10/64, to pdf on Chrome, MS Office, GIMP, OpenOffice, and probably Firefox.
