[xep-support] Re: Image resolution in PDF output

I am trying to understand the question.


1) If an image has no resolution inside the image itself, it will be treated as 120dpi – this applies to bitmap images only.

2) If an image has a resolution, it is used


**Now, this means only that whatever size you tell the image to be, it is placed “as is” inside that container as is. Nothing is done to it. No resolution is changed at all.


3) If you are using SVG’s, there is no resolution (except for any bitmap you may have inside the SVG). A circle is a circle, a line is a line and a rectangle is a rectangle. They are not bits of data. It is drawn into the PDF as vector directives.


So to create a “print quality” PDF, insert bitmaps into the PDF that are 300dpi at the size you are specifying for them. SVG has no impact on this as there is no “resolution”.

Subject: [xep-support] Image resolution in PDF output


From what I saw in the user guide, it seems that the image resolution defaults to 120dpi when not set in the image description (for PDF output). I need to create PDFs with a resolution of 300 dpi (press quality) but can't find how to modify the default resolution. I'm using SVG graphic files and, by definition, they are resolution independent. Does anybody has had the same issue and found a solution?
Thanks & regards,
