Adjust Brightness, Contrast, Gammar & Fit width advanced

[doquan0]

I'm using PDF-XChange Editor 6.0.318.1 x64

A lot of my pdf files are scanned documents, so I really need a feature to change the brightness, contrast & gamma temporary to clearly see the content of those documents.

Also, my pdf scanned documents have different sizes (A4, A5, etc) for each page. Is there any way that all the pages will be aligned left when I choose View - Fit width & View - Page Layout - Continuous.

I have found a freeware program called STDU Viewer. This program has the above mentioned features and I really appreciate the developer team of PDF-XChange could consider to add those features into future version.

Thanks.

Hi doquan0,

Thanks for the post - We do already have an outstanding feature request for altering brightness, contrast, gamma, etc. However, this is not a trivial implementation and is considered a long term request. Also, please note that we rarely guarantee the implementation of new features, only that they will be given serious consideration.

Regarding the following:

I'm not entirely sure that I understand. Can you send a screen-shot that demonstrates what you're looking for?

Thanks,

Hi Will

Here is the screenshot for your consideration:

Some helpful notes:
- The left side, STDU Viewer, is what I want my pdf files to be displayed
- On the right side, PDF XChange, I have chosen View - Fit width & Page Layout - Continuous
- I don't know how STDU Viewer can display my pdf files really clearly. I mean, the text in PDF-XChange seems to be blurred (unless I zoom in), not as clear as STDU Viewer and also Nitro Reader. I attached the scanned pdf file for your reference.

Hi doquan0,

Thanks for posting this screenshot. That is an interesting feature request. I have submitted an official feature request ticket
RT#3720: FR: Variable Zoom in continuous mode when pages are different sizes

As Will said, we cannot guarantee that the feature will be added, only that it will be seriously considered by our development team.

Thank you for your understanding.

Cheers!

Hello,
was this feature implemented then? I want to play with contrast, brightness, etc. Feature "Enhance Scans" is awesome, but some pages need finer tuning. Regards

Hello, xpdf29349521

I am afraid that as of now, this ticket is not in progress, It does not seem to have been rejected, but neither has it been approved or assigned a work item number. At this junction, I can only say that the dev team has likely seen it, and considered it not to be a priority at the time. Perhaps it will be reconsidered in the future.

Kind regards,
