Subject: AW: [docbook-apps] intrinsic size of images

Title: Re: [docbook-apps] intrinsic size of images

Hi Ron,


I’m sorry for bugging you, but I sent you an example with images.

The images are created with Gimp. All 96dpi. They are 1inch 2inch and 10 inch big.

I’m using


scalefit="1" width="100%" contentheight="100%"


All images are scaled to maximum size.

I don’t get it. There must be a way!


I’m either made a big mistake or omething is awfully wrong.


I also attached the pdf so you don’t have to generate it.

Hi Hinrich

Using something like Graphic Converter you can pre-process your images to whatever dpi you want


<picture><size><scale> and set X- and Y-Resolution in pixels per inch.  You can also change picture size etc.

This will not of course create more detail, but it will give you whatever dpi you want.



Hello everybody,


we are using several tools for making screenshots.

The Problem is they all use 72 dpi for the resolution.

I read all the image sizing information, and set following attributes:


scalefit="1" width="100%" contentheight="100%"


But as I said, the images have the wrong dpi. (Jpeg)

I tried to modify the dpi with Gimp (print size), with no effect.

Now I foud out there is the so called Exif header. I modified it without any effect either.

I just want to set 96 dpi to all of our images.

I guess that Fop is a problem here.



How can I change the image resolution so that Fop understands?

Can I set a fixed dpi somewhere?
