|0015837||Scribus||Import / Export||public||2019-10-04 13:44||2019-10-05 17:47|
|Platform||Distro packages & Appimage-SVN||OS||GNU/Linux Kubuntu||OS Version||18.04.2 LTS|
|Target Version||Fixed in Version||1.5.6.svn|
|Summary||0015837: Import of Tiff files: the default resolution unit should be "per inch"|
When importing a new tiff image on the canvas, this one appears with a resolution of 72ppi. Even if the file has Resolution.
|Steps To Reproduce||1. Save the test.tif file in attachement. You can test the file with Imagemagick in a terminal "$ identify -verbose test.tif | grep Resolution" → (output Resolution: 508x508)|
3. Open Scribus , a A4 , drag and drop the tif on canvas.
4. The tif will appear bigger than a 2cm x 2cm box.
|Additional Information||Tested and reproduced in latest 15.5 appimage, 1.4.8 from Ppa package.|
Tested and reproduced with other regular ppi: 300, 96, 600...
|Tags||dpi, image, ppi, TIFF|
test.tif (1,602,288 bytes)
In fact your file does not specify if the resolution is expressed in dot per inch or dot per centimeter because the resolution unit tag is missing.
Hi @jghali. Thank you for the quick answer!
So do you think I should bug report that to Krita team?
Or is it a unit (per inch) that Scribus could assume in case missing instead of falling back to 72ppi?
||I have to check what TIFF specs says about resolution unit tag. I'll have to do that later tho as I have to quit my hotel room in a moment. I tend to think that we should probably use "per inch" unit as default. However it would be good if Krita would set the TIFF resolution unit tag properly.|
Nice. No hurry, I'm not in a workflow breaker situation: I'm even using other file format as TIFF in my project right now and I'm using Scribus 1.4.8.
So, +1 for the "per inch" by default. I'll report this one to Krita.
||Ok, so the old TIFF specs says that the default resolution unit is indeed "per inch". So I will modify 1.5.x code to define this default value properly. I won't modify our stable 1.4.x branch however, as I fear that change may cause some document breakages.|
Thank you again for having a look and fixing it in 1.5.x !
True, I totally understand for 1.4.x documents, that's wise.
