CreateGdPictureImageFromByteArray with PDF

[rens012]

Hi,

I have the following code:

int ImageID = oGdPictureImaging.CreateGdPictureImageFromByteArray(ref file);

oGdPictureImaging.PdfAddGdPictureImageToPdfOCR(PdfID, ImageID, TesseractDictionary.TesseractDictionaryDutch, "C:\\Program Files\\GdPicture.NET\\Redist\\OCR", "");

oGdPictureImaging.PdfOCRStop(PdfID);

The CreateGdPictureImageFromByteArray return a 0. the byte array contains a PDF file.
Is it impossible to create a gdpicture image from a PDF byte array?

Thanks.

Ok, I found in the manual that gdpictures cannot be created from pdf.

This means that i have to use the gdviewer to create an OCR'd pdf from a pdf file. (with the PdfRenderPageToGdPictureImage function)

This is a problem, as i'm not building a forms application. Is there any other way?

Hi Loïc,

I downloaded the new 6.5 version. But it seems I still can't create a searchable PDF from an existing PDF file with just the GdPictureImaging class.

Can you help me out?

Kind regards,

Hi,

This feature have been reported to GdPicture.NET 6.6, we got too many troubles with the current beta implementation.

However, you can use the GdViewer class in formless process, just implement is like

Code: Select all

Dim oGdViewer as GdViewer = New GdViewer

Kind regards,
