Hi, sorry for my impatience but I'm curious when the SDK for your Editor will come.

Hi! I'd like to make a snapshot of an actual page but only of its visible part. How could I get the coordinates of that area?

Thanks for your replies!

Hi, Ivan! I've read in your post your statement that "using a printer to convert an existing PDF to a PDF never is/was a good idea". 1) Can YOU advise me another way to convert a PDF? 2) Enclosed you will find in my attachment an illustration of a phenomenon I've found converting a pdf wit...

Hi! :D I've discovered the following phenomenon. I've tried to convert a pdf document including vector graphics into a BW one printing it into a file (as it's described above). Then I found out that the vector graphics were converted into a bitmap (I suppose it's so) with a quality loss (please see ...

Hi! Maybe I'm too fast, but I'd like to know when the PDF-XChange Editor SDK will be available. I'm testing the end user free version I've downloaded from this link: https://www.pdf-xchange.com/PDFXVE3.zip In the application directory of the new PDF Editor I've found the PDFXEditCore.x64.dll file. C...

Happy New Year!

Hi! I've found the differences between your code and mine in the sample program. These were commands setting the DevMode properties. I've altered my true program a little bit and tested it. Now it works! Thanks a lot! I'm really happy now! :D :D :D These are my code snippets (C#) in the last variant...

Hi, Vasyl! It functions perfectly, thank you very much!

Hi, I've installed these packages on a new virtual machine: PDF-Tools 4 SDK PDF-XChange 5 API PDF-XChange Viewer SDK In the application directory of my program I have amongst others the following dll's: AxInterop.PDFXCviewAxLib.dll 1.0.0.0 05.01.2012 Interop.PDFXCviewAxLib.dll 1.0.0.0 05.01.2012 Int...

Yes, Stefan, you are right, as always, I do need the rulers (but without the context menu).

relapse

Hi! Starting my program I forbid all context menus using the method

Code: Select all

SetProperty("General.DenyAllContextMenus", 1)

This seems not to be applicable to the context menu over the rulers. How could I disable that one?

Thanks for your replies!

relapse

Hi! Sorry for my long silence. I'll try to install all the things on a new virtual machine in order to test it properly. Thanks a lot for your reply. I'll surely inform you about my results.

Hi, Stefan! Thanks a lot for your detailed information!

So, I should directly create an annotation line with the Low Level API otherwise I couldn't find the annotation again that I'd created with the PXCp_AddLineAnnotationW method. Is that right? Could you eventually extend the PXCp_AddLineAnnotationW method so that one can also define the name property ...

relapse

Hi! I tried to find a possibility to set the name property for a line annotation, which I created with the function PXCp_AddLineAnnotationW but found nothing of the kind. Is it so?

Thanks for your replies!

Hi! I've tried your code sample and I detected that after the command: PDFXCviewAxLib.IPDFXCargs outArgs = (PDFXCviewAxLib.IPDFXCargs)selectedAnnotPageAndIndexOnPage; no code is executed. So I've modified it a little bit this way: if ((e.type == 4) && (e.name.Equals("Notifications.Selec...

relapse

Hi! How can I detect it? I already can test whether an annotation is selected: pdfViewer.SetProperty("Notifications.Selection.Filter", -1, 0); if (e.name.Equals("Notifications.Selection")) { AnnotIsSelected = true; } But how could I get a message from the viewer when the selected...

relapse

Sorry but it doesn't help

Maybe I've installed something wrong.

relapse

Hi! I've just installed the last build of the viewer SDK (2.5.207 instead of 2.5.205) but it doesn't function. Maybe the bug fix isn't yet in that version?

relapse

Hi Stefan. I'm glad to hear that, it's a good feeling to help improving your product. P.S. I've read my messages once more and came to conclusion that it may be not distinct enough what the problem was :D. The only thing I was irritated with was the size of the original object in the converted docum...

relapse

Thanks, Stefan! I've noticed that if the DevMode block is commented out it affects some little difference in the converted file. Please see the screenshots in the attachment.

relapse

Hi! I assembled a test application on the base of your "FullDemo" sample, because it was the quickest solution. The files are in the attachment. Thanks a lot once more!

Hi! Thanks for your effort! I'll try to assemble such a sample project but it will take some time.

Hi! I've recently tested my program only with an A4 document, it functions perfectly, but now testing it with documents of other sizes I discovered again that I have the problem as the converted document has other size as I set it in my source code.

Hi! Can I programmatically bar the PDFXChange Viewer from loading/parsing all system fonts on each start?

Hi! I surely can print a loaded file using the command (related to my last message) pdfViewer.PrintDocument(_documentId, PXCVA_Flags.PXCVA_NoUI); where the second parameter disables the user interface e.g. the save dialog. The destination file is to be defined as follows: PDFPrinter.Option["Sav...

Hi, Stefan! Thanks for your quick reply! If I don't want to have a viewer .exe in my application directory, could I print a loaded document to a temporary file with the viewer library? If I could, then I need a possibility to define the destination file, but I haven't found any for the PrintDocument...

Hi! I'm trying to print a pdf file grayscaling it. I've achieved it but now I have a new problem trying to extend the present functionality.

I've found the missing DLL, but in the sample directory of PDF-XChange 5 API: C:\Program Files\Tracker Software\PDF-XChange 5 API\Examples\Bin\C#\Interop.PXCComLib.dll Why is it absent in the directory of PDF-XChange PRO 4 SDK?

Hi! I have a new issue: I'd like to install my program on another machine. Currently it doesn't function, I'm getting an error message "The image format is not recognized", but I still can't localize it. I suppose this behavior depends on the fact that not all components are installed on t...

Hi, Stefan! You are the best :D as usual. But one more question on the documentation of the PDF-XChange Drivers API, I use the file Books-PDF-XChange-Drivers-API.pdf. I found no reference to the section of DevMode! Why? Is there another documentation for your drivers API? Thank you very much for you...

Sorry, I couldn't reply earlier. It seems to have no effect. I place here one more time my code: PDFPrinter.SetAsDefaultPrinter(); bPXCPrinterDefault = true; PDFPrinter.Option["Graphics.Color.Convert.Method"] = 1; PDFPrinter.Option["Graphics.Color.Downsample.To"] = 300; PDFPrinte...

Thanks a lot, it functions!

Code: Select all

Hi! Executing the command

Code: Select all

I get an ArgumentException that informs me that the value (I guess the value of the argument) is out of range.

Hi! My question is: Could I activate an annotation without clicking on it, simulating a click event? The background is: I have a toggle button which creates/deletes a selection area on loaded pdf document. The PDFViewer is a user control on my form. I'd like to have that selection area marked up (it...

Hi! Sorry, I was ill last week, and I couldn't post my reply.

Hi, Stefan! I've read in the js api reference that there are two dpi values to be set in a pdf document: bitmapDPI and gradientDPI. In my test file they have the values of 300 and 150 dpi respective.

And a further question from me: I can't find the proper settings to manage the size of the destination file? I've tried to use the following commands: PDFPrinter.Option["Paper.SheetWidth"] = 1110; PDFPrinter.Option["Paper.SheetHeight"] = 1110; but it didn't help me. To illustrate...

Hi! I have then one more theoretical question. In the coming version of the Viewer it will be possible to alter text in an existing PDF file. Will it also be possible to do it with a converted PDF file, where the formatting information of the text isn't complete after the conversion (in this case - ...

relapse

But as I've described the situation it's possible to access the text using the option "formated copy" in Acrobat. Maybe there is also such a function in PdfXChange Viewer???

relapse

Sorry, it was a false parameter notification. It should be the following one:

Code: Select all

PDFPrinter.Option["Graphics.Color.Convert.Method"] = 1;

To expand the last thing I addressed in my last message: Is there any possibility to force the formatting of the text to be kept after such a conversion?

Hi! I've tried to set some printer options in the procedure bFilePrint_Click after defining it as a default printer with the command SetAsDefaultPrinter() but in vain: PDFPrinter.set_Option("Color.Convert", 1); I've also got no positive result trying to retrieve the value of a printer opti...

Step by step it's going to be more understandable for me

One more question, how could I set the output of the file to be converted as a pdf file?
