Screenshot of gwenview and okular
I attached a screenshot of my Desktop showing the file with okular and gwenview side by side.
I just wonder, do you have the okular tiff backend installed? (it is part of the okular-extra-backends package) Created attachment 54581 [details]
PDF print from okular
The okular-extra-backends Package is installed. I removed the Package from the system and tried again, with the same result. So maybe "Component: TIFF backend" is not correct and should be more general? If I print the tiff into a PDF File using cups-pdf the result from okular is attached, same procedure from gwenview looks good.
I can confirm that it looks blurred on screen, i don't have a printer at hand to try to print it. Blurring on screen is basically by antialiasing and i'm not sure "that's a bad thing" in general but i can see how it may make it a bit harder to read for this particular case. Been searching for this for ages :/ This bug is still present (using openSUSE 42.1 Leap here). Printing 600dpi 1bit tiff file from any application (Gimp, Gwenview, cli,...) is ok but Okular prints 'fuzzy' image. OP stated that there should be text in the document ? In my case it doesn't matter, pure images also print fuzzy. |
Created attachment 54197 [details] 600dpi Tiff file Version: 0.10.5 (using KDE 4.4.5) OS: Linux By opening a scanned monochrome .tiff file in okular, the font is displayed quite blurry and so it looks like when printing the file. Opening and printing the same file with gwenview leads to a good result. Reproducible: Always Steps to Reproduce: Open the attached file with Okular and open the file with gwenview. Compare the screens and print it from both programs. Actual Results: The okular screen and printing is blurry compared to the gwenview screen and printing which looks quite good. Expected Results: The screen and printout should look the same with both applications. From a short test with another scanned .tiff I couldn't reproduce the behaviour with a scanning resoltution of 150dpi. The attached file was scanned using 600dpi.
