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

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.

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

I also opened in GIMP, copied into new image, set the print size and saved
again.

No change.

I would like to know what part does not understand the dpi?

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.



Thanks,

Hinrich
