We know that Xbrowse is the most powerfull browser and PDF's are the most used document files. I'm not able to show the pdf's like we do the jpg, bmp in browse.
From a post yesterday mr. Rao had these options. Can it be converted to include the viewing of pdf's ? At this point I need a 3the party to convert the pdf to jpg for browsing large data files.

Sample with XImage (from Mr. Rao) https://forums.fivetechsupport.com/view ... d4c4cf140f

The sample uses Memo files, but that is NOT needed. Just a lot of pdf's in a location on disk.

Mr. Rao, if you are reading this, you once placed a preview of Xbrowse showing the Pdf's. and lots of other extensions. I would be happy if only the Pdf's can be added for this time.

Hi Mark,
The provided code in ScrnShot.Prg is a FiveWin/Harbour program containing several functions for capturing screenshots and converting files into JPEG images.
Best regards,
Otto

https://forums.fivetechsupport.com/view ... e8#p254919

The provided code in ScrnShot.Prg is a FiveWin/Harbour program containing several functions for capturing screenshots and converting files into JPEG images. Here's an explanation of the key functions and their purposes:

1. PdfToJpeg(cPDF)
Converts a PDF file to a JPEG image.
Steps:
Opens the PDF in PDF-XChange Viewer.
Captures the window displaying the PDF using WndBitmap.
Trims unnecessary borders (BmpTrim) and saves the bitmap as a JPEG file using BmpBufToJpg.
2. FindWnd(cTitle)
Finds a window handle (hWnd) by matching its title (cTitle).
Uses a loop to traverse through all child windows on the desktop.
3. BmpTrim(hBmp)
Trims black areas from the sides of a bitmap.
Calculates non-black pixel regions and crops the bitmap to reduce empty spaces.
4. WordToJpeg(cFile)
Converts a Microsoft Word document to a JPEG image.
Steps:
Opens the Word document using OLE automation.
Captures the displayed window content as a bitmap.
Processes and trims the bitmap (DocBmpTrim).
Saves the resulting bitmap as a JPEG.
5. DocBmpTrim(hBmp)
Similar to BmpTrim, but specifically optimized for trimming a bitmap generated from a Word document.
Identifies the document content area and removes surrounding borders.
6. BmpBufToJpg(cJpeg, cBuf)
Converts a bitmap buffer (cBuf) into a JPEG file (cJpeg).
Uses the FreeImage library for the conversion.
7. RTFToJpeg(cPDF)
Converts an RTF (Rich Text Format) file to a JPEG image.
Steps:
Opens the file in WordPad.
Captures and trims the displayed content as a bitmap.
Converts the processed bitmap to a JPEG file.
8. FindAllWnd()
Retrieves all window titles and their handles on the desktop.
Useful for debugging or identifying target windows for further processing.
9. MSGToJpeg(cMSG)
Converts an Outlook MSG file to a JPEG image.
Steps:
Opens the MSG file using the default program.
Captures the displayed content as a bitmap.

Processes and saves it as a JPEG file.
10. StandardDruckerUmstellen(cDruckerName)
Temporarily changes the system's default printer to cDruckerName.
Returns the previous default printer name for restoration.
11. change2default_printer(coldprinter)
Restores the previously saved default printer (coldprinter).
12. ENUMCHILDWINDOWS
A C function embedded with #pragma BEGINDUMP.
Enumerates all child windows of a given parent window (hWnd) and executes a Harbour code block for each window.
This enables dynamic interaction with GUI elements in other applications.
Main Use Cases:
File Conversion: Converts PDF, Word, RTF, and MSG files to JPEG images.
GUI Automation: Finds and interacts with application windows using their titles.
Screenshot Processing: Captures and processes screenshots of applications or files.
Printer Management: Temporarily changes and restores the default printer.

Thanks Guys ....

I'm using Poppler for converting

But in the topic Jimmy provided you can see that Mr. Rao did show PDFs from xbrowse with no conversions at all.

https://forums.fivetechsupport.com/view ... 32#p254887

Just the code for pdf's would be helpfull at this moment. Maybe at later stage Mr. Rao wants to implement it for Fwin Libraries. If testing purposes is needed, i'm gladly to help.

I have to setup the latest version that I do have, in order to try it (missing WebView) . Will try it this evening.

if use a different Path e.g. "G:\CT\" i need to include it in DIRECTORY(cPath +"*.PDF") else LEN(aDir) is Empty()

We already have a function for the last few years that can be used here.

Code: Select all | Expand

htmlview( "FullPath.pdf" )

This was working for the last few years but giving problems recently.
Note: This function uses the old IE Activex.
Can anybody try this simple code and let me know if it is working on their PCs?

I'm allready using htmlview and it works for me (opening adobe pdf) , but I have the issue that i can not position the HTML window. Otherwise I would position the html window at the same coordinates as the XImage and when scrolling the user would hardly see it.

With implementing I mean in the source of XBrowse.

Code: Select all | Expand

         WITH OBJECT :proefdruk
             :nEditType     := EDIT_GET_BUTTON
             :bBmpAction    := { || if(at(".JPG",oBrw:aCols[oBrw:nColSel]:VALUE)>0,XIMAGE(oBrw:aCols[oBrw:nColSel]:VALUE),HTMLVIEW(oBrw:aCols[oBrw:nColSel]:VALUE)) }
             :bEditBlock    := { |r,c,oCol| cResult:= LookupFiles("LOGOS",oBrw,oCol:value),oCol:varput(cResult) }
             :bRClickData := { |r,c,f,oStru| HTMLVIEW(oBrw:aCols[oBrw:nColSel]:VALUE,oBrw:aCols[oBrw:nColSel]:VALUE,oDlg,10,100,500,500) }
         END

Hi Mark,
when you browse with the arrow keys, do the PDF files open quickly enough to work smoothly?
Best regards,
Otto

but I have the issue that i can not position the HTML window.

Yes, we can help you with that.

We can use htmlview( c ) for pdf file, json files, xml files also. in addition to any Url or html files
With some modifications, we can also view any image file also.

For linking with XBrowse, we need to use a modified version of htmlview and we can provide the change.

Sadly on my PC viewing pdfs with html view is giving problems. I guess it is because of some web security settings.

Webview is working very smoothly. So I moved my previous code to WebView.

And yes, navigation speeds with arrow keys are good same like displaying different images.

Otto, It may look so, but the xbrowser is NOT showing the PDF content, while moving up/down just a icon of pdf file. I have to click on it to see the content.

So I hope that Mr. Rao will give Xbrowse the first position to move pdf code into it ))))))))))

Hello Mark,
Where do you need this preview, and do the PDFs change often?
After realizing that opening the PDFs is too slow for a "visual-manual" search, I chose the approach of converting the PDFs into image files using the code I posted here yesterday, also for DOC files. This way, you can view the images in XBrowse, and if something is interesting, open the PDF.
I don't think it works to open PDFs in real time.
Best regards,
Otto
