Description Jens Reuterberg 2013-06-13 11:48:34 UTC

I exported the kra files to ORA since I wanted to open them in Gimp to add text. The original files where 300x300 ppi but when I opened the ora files in Gimp they where 72x72. There where no choices to specify the ppi settings and it didn't force the 300x300 setting either.

Reproducible: Always

Steps to Reproduce:
1. Save a 300x300 ppi KRA file
2. Export to .ora
3. Open .ora file and check the image properties
Actual Results:  
The file is 72x72 ppi 

Expected Results:  
Either force the original ppi onto the .ora file as well or allow for a setting where the ppi can be specified.

There are ways around it though - you can export it as something else instead of .ora but considering how versatile .ora are (since most programs accept the file format) it would be good not to have to.

Hrm... OpenRaster doesn't specifiy a resolution, probably because mypaint doesn't support that. Let's see... The embedded png files should have the right resolution in any case.

Load the resultion information from the embedded PNG images

Now Krita can roundtrip the resolution information in ora files,
but other apps will still reset that to 72 DPI. We need to extend
OpenRaster for this.

Mailed http://lists.freedesktop.org/mailman/listinfo/create about extending the spec.

Created attachment 85260 [details]
The patch adds the resolution information to the xml file of the ORA.

Krita, now saves the X resolution ( "xres" ) and the Y resolution ("yres") in the stack.xml file of the ORA, while saving the file. And, while loading the .ora file, it searches for "xres" and the "yres" information in the stack.xml file. if found the value of resolution is set to the corresponding values of resolution else the The default value that is 75 ppi is set as the resolution.
