PDF Export: ColorSpace and BitsPerComponent

[Fabio Pagano]

I need to create a PDF with following specifications for images:

/ColorSpace /DeviceGray
/BitsPerComponent 1

Actually, when i export pdf, in the pdf text (i see it opening the pdf with notepad) i see:

/ColorSpace /DeviceRGB
/BitsPerComponent 8

for each image.

Is it possible to create a PDF with ColorSpace=DeviceGray and BitsPerComponent=1 in its images?

Thank you.

Hello, Fabio.

Do you wish to export all images as monochrome?

Thank you.

[Fabio Pagano]

Yes.

Dear Fabio,

We have added this to our to-do list.

hi

I have a similar request - for TIFF format.
we are exporting documents into e-archive and we want to reduce the file-size as much as possible. so TIFF with monochrome option would be very helpful.

btw we also use PDF with monochrome with some other clients, so fabio's request will also be helpful.

thank you

In update of 9 february 2010 i read:

"Upd: Some improvements in the PDF export."

Is this the possibility to export all images as monochrome in a pdf file, as i requested?

Thank you.

Hello,

We made some improvements in export to PDF.
Now you can export images as monochrome.
You can use following code, for example:

Code: Select all

            Stimulsoft.Report.Export.StiPdfExportSettings exportSettings = new Stimulsoft.Report.Export.StiPdfExportSettings();
            exportSettings.ImageFormat = Stimulsoft.Report.Export.StiImageFormat.Monochrome;
            exportSettings.DitheringType = Stimulsoft.Report.Export.StiMonochromeDitheringType.FloydSteinberg;
            report.ExportDocument(StiExportFormat.Pdf, @"d:\test.pdf", exportSettings);

Also you can select monochrome mode in export setup form, in ImageCompressionMethod combobox.

The patch will be available in the next prerelease build from 9-Mar-2010.

Thank you.
