PDF output is slow to render

bwelsher · Postby **bwelsher** » Tue Mar 12, 2019 10:21 pm

Hi all, hope this is the right place to ask.
I have created a number of files in Inkscape that, when I save to PDF, render very slowly and progressively when opening in Adobe Reader. They aren't complex files as far as I can see and I am using the default PDF export options (1.5, rasterize 90%, doc page size). I would really appreciate it if someone could spare the time to look at the PDF below and see if they have the same issue and if so what might be the problem in the SVG.
Many thanks
Ben

The PDF also opened progressively for me, but it only took about 2 seconds. That actually is a fairly complex file.

I don't really know if it's normal and expected to open progressively like that, or not. I certainly have seen it before though. But why is it a problem for you? Does it open slower than a couple of seconds for you?

you have more than 250 flowed text objects. Inkscape will convert these to regular text when rendering to PDF which takes a while. Consider using the convert to text command to change all of these to regular text. It saved as pdf and opened the pdf too fast for me to time it. So no more than 0.05 sec each time...
No sectional rendering either.
Hopefully you can uncompress a 7z file. See if this renders to pdf quickly.

I simply used the "clean document" operation and the exported pdf opens instantly.

Actually, I don't even need to clean the document (I do that reflexively/compulsively).

Just saving a copy as PDF (v1.5, raster=300, doc pagesize) makes a pdf that opens instantly.

I see the OPs svg file is made with Inkscape version .91. The generated pdf shows Cairo version 1.11.2.

Might be good to update to at least .92.2. Cairo image processor has been upgraded to 1.15.6.

Here's the version simply opened in Inkscape .92.2, and saved a copy as pdf.

Funny, I did that too without even thinking I don't think it was more than 10 defs though

Thank you all for your feedback. I think I tried just about all the suggestions without any noticeable improvement but a simple upgrade to 0.92 was what fixed the issue in the end.
Thanks again for the help.
