PDF compression methods in GD picture version 10

[joastr0815]

Referring to GD picture version 10: Which compression methods are used for creating PDF/A (searchable) and PDF (searchable)?

Hi,

It depends on the class used and on the compression scheme you have specified through the method designed to specify the compression.

With best regards,

Hi,
thanks for your reply.

We use object(class) GdPictureImaging for creating PDFs.

For image PDFs, we use these functions:
SaveAsPDF
SaveAsPDF_2
PdfCreateFromMultipageTIFF
PdfCreateFromMultipageTIFF_3


For searchable PDFs, we use these functions:
SaveAsPDFOCR
SaveAsPDFOCR_2
PdfOCRCreateFromMultipageTIFF
PdfOCRCreateFromMultipageTIFF_2

So what we need is the default compression scheme for color and monochrome PDF.

Best regards,
Joachim
