1. Please could you advise of the correct way to get the ID and correct parameters required for the parameter setting functions such as IMG_PageSetFormatLongParameter. We couldn't find a clear method in the documentation. We are able to successfully create JBIG2 files using the approach below, but n...

Attempting to read the attached PDF file gives the error above. It is PDF version 1.1 which is a little unusual these days, but the file does read OK elsewhere. All we are doing is : hr = PXCp_ReadDocumentW(pObject,CA2W(pdfFile),0); if (!IS_DS_SUCCESSFUL(hr)) { printf("Error Code %d\n",hr) }

neilpitman

Do any of the Tracker SDKs have the ability to convert PDF pages to a raster image format?

neilpitman

Presumably the declares change was to PXP_TextElement not PXP_TETextComposeOptions? I tried that but then get Error 3 The best overloaded method match for 'pdfinfo.XCPro35_Defs.PXCp_ET_GetElement(int, int, out pdfinfo.XCPro35_Defs.PXP_TextElement, int)' has some invalid arguments C:\dev\pdfinfo\pdfi...

Please could you advise of the solution for this problem.

Thanks for the guidance - we have tried as shown below but still get the "Invalid Argument" error. Is there an example available we can look at ? ......

We are find that PXCp_ET_GetElement always gives "Invalid Argument" - perhaps we are not using the correct calling sequence? Using 3.601131 VS 2005 project attached, and key code shown below XCPro35_Defs.PXP_TETextComposeOptions m_TextComposeOptions; XCPro35_Defs.PXP_TextElement m_tel ; Console.Writ...

This fix seems to have introduced a new problem.

When processing the PDF and extracting the image we now find that IMG_PageGetSize returns an incorrect value for height. It always appears to be the same value as width.

Let me know if you need more detailed information.

Thanks

Neil

Have I posted this to the correct forum? Just wondered why there wasn't any reply yet - usually you guys are very responsive.

When using 3.6021 processing the attached PDF file IMG_PageGetDPI and IMG_PageGetSize functions fail with Error code is: 0x82030001 Severity is: Error Facility is: ImagesCore Error is: Invalid argument There must be an issue specific to this PDF file as we have successfully processed PDFs from many ...

neilpitman

Could you clarify the current support and plans with respect to PDF/A support, and whether the support will include conversion of existing PDF files to PDF/A and whether it includes PDF/A verification.

Thanks

Neil

neilpitman

Thanks, that seems to have fixed the issue.

PXCp_ET_AnalyzePageContent crashes on the first page of certain documents, although the majority of documents are processed fine. I have attached two examples. We are using 3.60.1131. Please advise whether this reproduces at your end and may be a bug or whether there may be an issue at our end. Than...

The two main areas where XMP is important for PDF : (a) It is a requirement for PDF/A (see section 6.7 of ISO 19005) at both creation and modifiction time - eg updating xmpMM:History. (b) To provide additional indexing information that can be used when searching - eg after importing into Microsoft S...

neilpitman

Is there any explicit support for XMP in PDF-Tools or is it just up to us to use the low-level API (probably in conjunction with Adobe's XMP Toolkit) to manipulate XMP metadata?

Thanks

Could you advise the support position / timescales regarding the following with respect for the SDK?

Hi

Will 3.5099 be released this week?

Thanks

neilpitman

Is there any functionality in any Tracker library to save a complete page from a PDF document as an image file?

Thanks

neilpitman

It is possible to find the value of the ImageMask setting for an image using PXCp_GetDocImageAsXCPage? Or some other method?

Is there detailed PXC_Matrix documentation - we just need to understand the image placement information.

Thanks!

The attached PDF file gives the following error on IMG_PageGetDPI(). Many other files have no problem. This is with version v.3.5098 Error code is: 0x82030001 Severity is: Error Facility is: ImagesCore Error is: Invalid argument The image is extracted with : PXCp_ReadDocumentW(pObject,CA2W(PDF_FileN...

We are using build 91 and the problem occurs with the new example just posted although the previously posted example works fine in 91.

neilpitman

Build 88 fixed the problem for the original file but we have found another example which appears to exhibit the same problem. We have now also purchased Image-X Change but the problem still occurs on this new example even using PXCp_GetDocImageAsXCPage and IMG_ImageSaveToFile instead of PXCp_SaveDoc...

neilpitman

We are now moving our app to 3.5 so we need to be able to use the XCPage(?) method that was mentioned above to determine the X and Y resolution of the image so that we can save it correctly. Can you provide any pointers on how to do this?

Thanks

neilpitman

Thanks but the zip file was empty! Would you be able to repost? On a related note, to prep for using the 3.5 interfaces I'm trying to build the C++ TestPro35 sample in build 91. After adjusting for include and lib directories (from ../lib to ../../../lib etc) I found that ixc_c.h, ixcdefs.h, ixcfmtd...

Hi

For this project we use MS Visual C++ (not .Net) with Visual Studio 2003.

Thanks

neilpitman

The "correctly" rotated version (ie the way that it appears in Adobe Reader) that you attached is the desired result. We are using PDFXCp_SaveImageFromPage and find that the image is inverted and "incorrectly" rotated (file attached). Do we need to switch to making use of the 3.5 library calls? That...

Hi

A sample PDF file that demonstrates the problem was attached to the original post - if you can't read it for some reason let me know.

Thanks

neilpitman

Attempting to extract an image with PDFXCp_SaveImageFromPage etc from the attached sample PDF results in an image file which appears to be inverted and rotated 90 degrees from the PDF original. This is true using the SDK examples (saveimagesfrompdf, imagefrompdf) or our own app. Any workaround would...

neilpitman

Attached is another test file from a totally different source that also exhibits the "top half of an image" problem - would it be possible to confirm that the fix will also work for this file.

Thank You.

neilpitman

Any news on when build 88 will be available? We really need the fix ASAP.

Thanks

neilpitman

Attempting to extract an image with PDFXCp_SaveImageFromPage etc from the attached sample PDF results in an image file which appears to be just the "top half" of the image. This is true using the SDK examples (saveimagesfrompdf, imagefrompdf) or our own app. Any workaround would be appreciated. Thanks

neilpitman

Attached are examples of two problems that appear within the SaveImageFromPDF SDK example. (Both 3.4 and 3.5) The first file, hangloop.pdf appears to hang/loop on PDFXCp_ReadDocument whilst the second file, crash.pdf appears to cause a crash on PDFXCp_SaveImageFromPage. Our application using the sam...

Yes, it is the DPI that is being saved in the TIFF file incorrectly. Attached is the source PDF file with embedded image, and the resulting TIFF file : Code used is : Options.yDPI = 98; Options.xDPI = 204; Options.CompressionMethod = ImCompression_CCITT4; hr = PDFXCp_SaveImageFromPage(pdf, pagenum, ...

neilpitman

As long as there is only one image per page, using PDFXCp_GetMediaBoxForPage and PDFXCp_GetDIBImageFromPage enables us to get the size , height and width.

neilpitman

We find that using PDFXCp_SaveImageFromPage seems to ignore yDPI and use xDPI for both x and y resolutions. Hence the code below results in a TIFF file with 204 x 204 resolution. Is this a bug or is there a way round this? Options.yDPI = 98; Options.xDPI = 204; Options.CompressionMethod = ImCompress...

neilpitman

In image-only PDF files, many group 3 tiff images will be from faxes which can have resolutions such as 204dpi x 98dpi Before using PDFXCp_SaveImageFromPage we need to be able to correctly determine the image object size from the PDF file, in order to be able to correctly set xDPI and yDPI - setting...
