What steps will reproduce the problem?
1. Open scanned PDF with somewhat not perfact sharpness & clearity in contents 
(but not bad: "accepted") by EBookDroid

What is the expected output?
   Sharpness & clearity of characters & content appear as in ezPDF

What do you see instead?
   Clearity & sharpness in EBookDroid is less than ezPDF & this is more clear in landscape position.

What version of the product are you using?
2.1.9

On what operating system?
4.1.2

What device are you using?
Galaxy tab 7.7 (6800)

Please provide any additional information below.
   I try "Texture bitmap size" in "Rendering" of "Performance setting" & put it on 1024x1024 but no improvement. Please can explain for what could be used this option?

Texture bitmap size can affect on drawing performance on different devices. On 
modern devices use max.

Can you provide screenshots of your pdf in 2 apps? Also it would be perfect if 
you upload pdf (1-2 pages are enough).

File 1: screen shot from EBookDroid (in landscape, day mode, automatic crop, 
with fit to width)

File 2: screen shot from ezPDF (in landscape, day mode, menual zome to degree = 
to automatic crop in EBookDroid)

  Please look for 2 pictures carefully. To be more clear please open them & compare using laptop or disktop.

Picture 2 (ezPDF) is more clear than picture 1 (EBookDroid)

File 3: example from the PDF (page 1 is the page in screen shots)

  For such PDF I ask for add filters as in Perfact Viewer

  Best

Ok. I do see the difference. I need some time to think about what can be done.
