AW: [docbook-apps] intrinsic size of images

Hi Ron

I was trying to use Image Magick to change the dpi of the image. That would also change the intrinsic size afaik.

I can change the dpi, but it seems like FOP does not understand that.

When I open the image in Gimp, the intrinsic size is correct. (I used a ruler….)

Besides that there is the EXIF header. Is it used?

Thanks, Hinrich

Hi Hinrich

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

http://www.lemkesoft.com/

<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.

Question:

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

Can I set a fixed dpi somewhere?

Thanks,

Hinrich
