I noticed that the "Recompress Image" option is affected by "Undo", but not by "Redo". I assume this is a small bug?!

Hello, I just noticed an unexpected behavior of the Snapshot tool. It seems to do snapshots at different dpi settings than what the onscreen display is using. Here is a comparison of Editor's Snapshot tool vs. Windows Snipping tool doing screenshots at the very same Editor zoom setting. Editor's Sna...

How can I convert multiple images to monochrome (+JBIG2) at once? - The "Recompress Image" option in the content tool allows to convert images to grayscale, monochrome or b/w, but only one image at a time. - The "Save as Optimized" does not seem to offer any such conversion option at all. - PDF Tool...

Good news, thank you!

Timur Born

What exactly is not acceptable? That it does not behave like you expect or that a bug may be present that is currently investigated and may thus be fixed in the future?

Both the 32 bit and the portable version can scan 6 pages (12 sides) using the Twain 32 bit driver, only the 64 bit version of Editor is stuck at 5 pages (10 sides). So this is a conflict between 64 bit Editor and 32 bit Twain. On a side-note: The portable version wrongly identifies two additional T...

I finally found time to check this. 1. Assuming that: - you are still using 64-bit PDF-X Editor of build 326.1; - you use 32-bit TWAIN driver for your scanner, please try to reproduce the issue with renamed/deleted twaindsm32.dll in the Editor installation directory ("%ProgramFiles%\Tracker Software...

What is the consensus on this? Most of the documents I regularly use contain these "Multiply" layers that Editor cannot deal with but other viewers can.

Timur Born

I just realized that you meant the resolution test chart. It's the ISO 12233 chart, you can download a PDF version here:

Just use the Line tool in an empty document. Or use the sunstar from the test document in the following thread. https://forum.tracker-software.com/viewtopic.php?f=62&t=31457 You can see how stroke adjust (properly) changes the straight horizontal and vertical lines to 1 pixel width while all other l...

I see. I tried to set Multiply blend mode for the "T" text and indeed this turns off Cleartype rendering in Acrobat. That being said, most of the problematic PDF files I use Editor for are rendered using Cleartype in Acrobat and the other PDF viewers. So if Editor learns to render Cleartype when a "...

Timur Born

I am able to reproduce this. Do you use "Microsoft ICM" for color management in Editor? Side note: if you open the "bug" PDF file in Acrobat it says "Insufficient image data" and uses transparency instead of black. If you try to grab one of the transparent images an error pops up: "Insufficient data...

Side by side view does not offer to scroll both windows at the same time, though. This would help with manual comparison until a more automatic comparison tool is available.

Timur Born

When you write that Acrobat does "not use Cleartype always" I assume you mean that it uses its own type of sub-pixel rendering?! Because my example screenshot clearly show that Acrobat does use sub-pixel rendering for the font, just more subtle (less intensive red/blue). Or do you mean that Acrobat ...

Timur Born

According to a discussion from last year this is due to some kind of transparencies being present anywhere on the page (not necessarily anywhere close to the affected text). Once such a transparency is present Editor seems to switch off Cleartype. I own one PDF file were in double page view one page...

Timur Born

I am confused, Ivan. What do you mean by "renders e absolutely the same"? It's very obvious in David's example (and my Cleartype examples in a different thread) that "e" characters are rendered very different in Acrobat, with the "-" line being placed lower (and being anti-aliased in David's example...

Timur Born

No hurry, once I understood the problem I scanned using less pages per run and thus finished the scanned document.

Timur Born

It's not possible to cancel the operation once Editor gets stuck. The only way to get out is to end Editor via Task-Manager.

Timur Born

Great information. I assume that anti-aliasing will be applied at original resolution then as well and then left to the printer driver to upscale along with the image? If this is the case then resampling images outside of Editor makes sense when superior image quality is needed.

Timur Born

Unfortunately I ran into the next culprit today. Trying to scan double sided pages at 200 DPI via TWAIN it turns out that once I try more than 5 pages (=10 sides) XChange does not import the pages from TWAIN anymore. HP Twain claims to save the pages, but Editor gets stuck (no CPU load or anything)....

Timur Born

Usually I use Photoshop to upscale bitmap images to the scale I need and in the same step resample them to 360 DPI, the latter of which being the native resolution of my Epson 3880 in normal quality print mode. That way I ensure that the print driver does not upscale the final print image using its ...

Timur Born

To be fair , small "e" characters is something that not only Editor, but also Foxit and Nitro struggle with. No idea why their interpretation of the "-" height within the "e" is so different (and obviously worse) than Acrobat's. XChange Viewer does a bit better and is closer to Acrobat's rendering. ...

Hello.

I wonder if there is any difference in method and outcome between enlarging a page via "Resize Pages" option or just use "Fit to Printer Margins" to print a PDF on larger paper than the original size?

Timur Born

When will Editor learn to fully support sub-pixel font anti-aliasing (Cleartype) even when transparencies are present on a page? Currently Editor is not capable of sub-pixel anti-aliasing even when said transparencies are situated completely out of the way (like upper left corner). Here is a compari...

Timur Born

Great news, thank you! Several of my customers are architects, so lots of lines (CAD) are common in their PDF files.

Timur Born

Thanks for the hard work, Ivan! It's well appreciated!

This is "fixed" in 327 by activating Text Hinting (by default) No, the fix was implemented in a deferent way :) Text Hinting is and was activated by default from the very beginning of the Editor. What was changed, is the way we use FreeType library to render or outline glyphs. I still wonder why hi...

Timur Born

Even before 327 Editor had a tendency to render some fonts larger than Acrobat Reader. Maybe that tendency is further emphasized by the new implementation of hinting?

Timur Born

Editor turns 3 pixel lines into 1 pixel + 2 pixels of gray for anti-aliasing. Anti-aliasing thins the lines that started too thick to begin with. "Enhance Thin Lines" is permanently enabled. Acrobat Reader turns 1 pixel lines into 1 pixel + *occasionally* one or two pixels of gray for anti-aliasing,...

Timur Born

I think the main issue that Editor draws those lines too thick to begin with, anti-aliasing can only do so much to correct this if the basis is already flawed. As long as your lines are even thicker than what Acrobat draws using "Enhance Thin Lines" this will remain problematic. This is a bug of you...

Timur Born

It's a clear bug when lines thinner than 3 pt are rendered with 3 pixels, so a fix would be very welcome.

Timur Born

The reason for the sun-star to turn black at small magnifications is because of resolution limits and that Editor draws those thin lines as thick lines. You will get similar (but still somewhat better) results in Acrobat Reader when you enable the "Enhance Thin Lines" option. Editor needs to learn t...

Timur Born

Now that 327 is out, any news on this?

Timur Born

All I can say is that with hinting disabled a 6 still is bigger than a 4 or 5 in the test document, but only for True Type. But at least hinting solves that now.

Timur Born

Maybe consider adding the previously "accidental" rasterization as an option? Because depending on the printer driver (settings) the pre-rasterization of 326 can be superior to the vectors of 327. 326 rasterized version left (bitmap printing manually set to pure black and driver anti-aliasing enable...

Timur Born

This still begs the question why the Type 1 version keeps all characters at the same height, while the True Type version increases the height of (curved) characters? This is inconsistent at least, I would say even bugged. I noticed this uneven character height with various documents/fonts in the pa...

Printing to Postscript printer: Acrobat (left) vs. Editor (right) Resolution is increased, especially towards the center of the circle and where line width and spacing is concerned. I suspect that Editor is not capable of sending native Postscript while Acrobat Reader specifically is (Advanced Print...

Timur Born

Adobe's rendering is the reference, independent of whether we like one rendering more or less than the other. Cleartype aka sub-pixel rendering considerably increases the horizontal text rendering resolution. The "grid" is a lot less coarse and higher resolution means better representation. Furtherm...

Timur Born

I only did some very quick tests yet. There are some issues introduced with the new rendering. You might have noticed in your own scan that the resolution towards the center of the upper right sunstar decreased compared to the previous (pre 327) rasterized version, or at least replaced aliased lines...

Timur Born

- deleted everything I wrote -

Turns out that from the many, many, many test prints I did lately the option to "print as image" was still enabled. So the blame is on me for not testing 327 properly, sorry for that.

Timur Born

327 does not seem to fix this issue.

Timur Born

I just did a quick comparison, but from that I would judge activated text hinting as beneficial. Not only does it bring Editor's rendering a bit closer to Acrobat's rendering (reference), but it also makes small text more legible (especially "e" type characters). Unfortunately Editor still is not ab...

Works like a charm. And as long as "Commenting" is allowed you can even change the document when "Changing the document" is not allowed. Too bad that comments take so long to load on tablets.

Timur Born

One more feature request concerning the "Highlight" tool: Please add (parts) of the highlighted text to the comments pane, similar to how stickies and typewriter comments work. This would allow to remove all author, status and date parts of the pane and thus take less space. At the same time the com...

Timur Born

There is another drawback to the destinations and comments approach: it only works with unlocked documents that allow you to save them. The benefit is that once you are able to save them you can use them on all computers and even tablets (will take some time for tablets to read them in). But again t...

PDF Viewers on the iPad also display PDF bookmarks as "list of contents" (index) and then offer additional "bookmarks" that do exactly what you (and I) need. The cave-at is that these "bookmarks" only work within the same application, even to the point that when you copy the same document back and f...

Ahoi!

Don't you think it is time to rename the "Select Text" button to "Select", seeing as it selects text, images and now even 3D objects?

Absolutely +1! Please make use of my computers resources in order to give me a faster PDF experience. On that note: I am still hoping for any PDF Viewer to at least match the search results (sorting) of OS X' Preview.
