PDF XChange Forum

Hi Christia. This function is PXCp_PlaceContents :) For example you need place first page from source document over first ten pages of destination document. You may write for (int i = 0; i < 10; i++) { PXCp_ContentPlaceInfo place_info; place_info.DestPage = i; place_info.SrcPage = 1; place_info.Alig...

The Problem is that your document uses embedded fonts, which are in many cases drawn as curves (at least for now). However even we are able to draw text using the font embedded in the pdf as text you will not get correct text when select it and copy - this is because character codes are lost during ...

Hi Christina. There are several ways to do this: 1. If the source PDF page contains ONLY an image the best way is to use the PXCp_PlaceContents function to place this page on all needed pages in the destination document in one operation. Of course you may make several calls, but this will make the P...

One more possible solution: 1. Run Viewer, open File Open dialog and resize it and preview window to maximize preview. 2. Select file in dialog and shortly you will see it preview. 3. Press right mouse button and select rename from context menu. Repeat steps 2 and 3 untill all files renamed as neede...

Please send it to me - lazycat@tracker-software.com

The Non-portable version store's settings in the registry, so you need to export HKEY_CURRENT_USER\Software\Tracker Software\PDFViewer from backup and import it on new OS.

The Correct way to keep settings - export them before reinstalling OS and later import them.
HTH.

Hi Christina. I'm afraid that xcpro40 does not support such optimization options (I mean finding dupplicated images and remove copies). Function PXCp_AnalyzePageContent was designed as part of text exraction mechanism, so it simply abount the PDF file and PDF document structure). We are looking to e...

Can you provide a file which open faster to us? Will see where is difference.

Hi Martin. Yes, this is images (and may be other temporary data such as fonts, but fonts are often much smaller). More helpful information will be the PC configuration where a file renders slowly: OS version, CPU, RAM (size and maybe speed), HDD model. However regardless of this information all we c...

Your file contains a large Raster image (about 24.8 Mbytes), and we place the decoded image into a temporary file. Different windows versions have different strategies when actually writing a temporary file to the hard drive, so we can get very different results. If the target PC has not so much RAM...

Hi Christina. The most time consuming operation is adding an image, and I'm affraid that we can do nothing with this - during adding image we must decode it and convert to one of the formats, supported in PDF standard. If your image is a large raster image - it will take significant time. However th...

In most cases reprinting PDF file to another PDf file make text unserchable - you can read it, but get garbage when try to copy selected text. And in many cases text may be printed as image or curves, so you will be not able even to select it. Best solution is to obtain "owner" password (p...

Actually Viewer now support dynamic stamps, but they not included into distribution file. So if you have appropriate stamps - just copy them to other stamps location (in XP: "<DriveLetter>:\Documents and Settings\<User>\Application Data\Tracker Software\PDF-XChange Viewer\2.0\Stamps\" in V...

It is impossible to install the plugins separately - they require the installed version of the Viewer. The Difference in size is because the installer includes: 1. 32-bit application and required resources (all the content of the portable version). 2. 64-bit version of the Viewer (for use on x64 sys...

We cannot configure overlap in text lines or something similar - some PDF files have no text or have text with very different font sizes.

All we can do - is set the overlap in points (so it will change with the zoom level), or as a % of the document window, or in pixels. I don't know what is better.

One other possibility - create a blank page, place the stamp over it, set the desired opacity and save the file.

Than create a new stamp from this page. But please note that you will be not able to change/remove the opacity in such stamps, just add additional opacity.

Sorry, but we cannot reproduce your behaviour. In fact scrolling up and down has no difference in code, so they both should work (or not).
Can you provide us step-by-step instruction how to reproduce your bug? Also, do you use touchpad or mouse for scrolling? If touchpad - can you try use mouse?

Portable version does no integration into your Windows OS, so it does not include browser plugins (to View PDF files directly in your browser), shell extension (additional information about PDF files in the properties dialog and preview in Windows Explorer, no search functionality in PDF files using...

Problem is reproduced and fixed.
Fix will be avail with the upcoming build (175).

Do you have same behaviour with portable version too?
Also, do you have any AntiVirus software running?

Answer is NO for xcpro and YES for PXCV. Please see documentation for PXCV_ReadDocumentFromIStream function.
HTH.

And please supply a code example which illustrates the problem (if possible).

Yes, in theory it is possible to write a program for Win/Mac/Linux platform, but this will makecode too complex and time consuming (at least for now for our team). Viewer was never designed to be a cross-platform project for many reasons (and complexity and money were not only reasons), and I'm affa...

You can download free version and try. Of course you will get demo label when try to save modified document, so do not overwrite original document. But as I remember if you have valid v2 serial (PVP20-...) you will need just download latest installation and it should work. In other cases you should ...

Version is 2.0, build 3.1

Which version? It is too old or you made misstype.
Anyway recomendation is update to the latest release (2.0.44.0 at the moment) and try again.
And if problem still exist - please send us one of such files to reproduce and fix problem.

Ok, I see the "problem" for example on page 9. This is typical situation in some pdf files - there is text and no space characters between words. In such case programs add spaces, and there is two cases: 1. Plain text, in this case inserting one space give good result. 2. Text, formatted u...

Sorry, but to attach files on this forum they must be archived (zip/rar/7-zip formats are acceptable). Reason is simple - we need to check file integrity before investigation (saving disk space and traffic is also good idea).

Since you have 64-bit OS best solution is check is there and upgrade to your translator. If yes - you will get it working with all 64-bit programs. For now you cannot install 32-bit viewer on 64-bit OS. And to set file association to portable version you should open context menu for any pdf file, se...

Does your translator support 64-bit applications?

As I said before - step 3 is very important. If you have some problems sending email - just save message and attach it here. If you have no e-mail client installed (or it does not support MAPI) - use following command line: PDFXCview.exe /FontList listfilename.txt where listfilename.txt is name of f...

Problem was found and fixed. Fix will be avail with updated installation (not later than next build).

If you still have problems please do following: 0. Make sure that you are using latest version (2.0.42.10 for now). 1. Make screenshot of problem view. 2. Make scrrenshot of Fonts tab in document properties. 3. On PC where problem exists Use Help -> Report a Problem ..., select all checkboxes (maybe...

Hi, In the current version of Viewer you need to react on PXCVA_OnNamedNotify. If you receive "Notifications.ContextMenu" in "Name" parameter then some context menu is being shown. To get the context menu name you can read the "Notifications.ContextMenu.MenuName" proper...

There are several problems in your code. 1. Main problem - Subtype must be Name , not String . 2. Minor problem - AP should be Dictionary instead of String , and it must contain N entry with correct Appearance Stream . Another option - do not set AP entry in annotation dictinary, it this case the Vi...

Sorry, but we cannot reproduce this problem with the portable version either. In fact there is only one important difference between the portable and installed versions - the location where the settings are stored (also the portable version does not provide plugins for internet browsers and shell ex...

Can you provide us sample of your code illustrating problem, and maybe resulting file? We will investigate and give you corrected sample.

If you are using the Driver's API to generate pdf files it is only possible to advise printing has completed. But after receiving data from your application our driver must analyze. optimize and generate thepdf content and save to file. All those operations are time consuming, so we've made them asy...

1. OCR is coming, but I'm affraid that it will ba added in V3 of Viewer (maybe not in the first builds, but not too far). 2. Actually ClearType is not compatible with current rendering model because add unwanted colorising and require up to 1.5-2 times more calculations (as result - much slower text...

For now - only using the Low-Level API.
You will need to know about PDF syntax and file structure (AcroForms, Pages, Annotations). If you have additional questions you may ask here.

We cannot open file in non-blocking mode - the PDF file as a whole is required to display, so non-blocking only possible in two ways - load everything in memory (very "good" idea for large files) or create a copy of file and open it. And for now you should not close the Viewer, but only th...

Problem is that incremental saving is required to keep all previous signatures valid, and currently - xcpro40.dll does not support incremental saving. So if the document was signed - the signature will became invalid after saving using xcpro. Incremental PDF save options will be added in the next Ma...

But are you able to add/modify other program defaults for PDF files?

Bookmark in PDF file is just a "pointer to position on specific page", but does not describe chapter or something similar, so we cannot determine what to print.
Sorry.

Hi Alexey. For now xcpro40 cannot create GoToR actions. If you want to use Low-Level API for this - you will need to add Link annotation on page with GoToR action. You will need to know the basics of pdf syntax (objects, dictionaries, arrays) and document structure (page dictionary specific, Link an...

Actually Auto setting for now is equal to 25% of the avail physical memory, so if your PC has 2GB RAM Viewer will use up to 512MB. Of course you can adjust this setting as described above, but note that this is the total limit per application, not per document, so if you set it to too low a value an...

Sorry, but the PDF format does not use carriage returns characters for lines separation. Each text portion (contained in PXP_TextElement) can be positioned anywhere on page, and there is no restrictions to ouptut text visually like Word11 Word12 Word21 Word22 in any order, for example Word22 Word21 ...

Please downloand Viewer installation again, manually uninstall and install downloaded one. Looks like you got wrong version

Sorry, but it is impossible to make such functions in the current realization. It is much easier to read the PDF and then modify (and much easier to create a new one). Regarding your code - you don't need to enumerate the entire page dictionary. For the first step I would like to recommend you to ta...

Reproduced with your file. Actually this crash may happen with many other files too - the problem was in not fully correctly handling subsequent calls to PXCp_ET_Prepare - now it is fixed. Fix will be available with the next build. And here are some notes about your code: 1. It is unsafe. You never ...

pxclib40 support four kind of images: TrueColor (24-bit RGB, each byte represent color component), Grayscale (8-bit gray, each byte represent gray level), Indexed (color image, up to 256 different colors, use indexes in color palette), and Monochrome (1-bit black and white images). For TrueColor and...
