Hello,

Im exporting a datawindow with the new feature of NativePDF on PB2019 R2 without using ghostscript. It works well but the images look pixelated. Someone knows how to solve this? My datawindows properties are this:

 

this.Object.DataWindow.Export.PDF.Method = NativePDF!

this.Object.DataWindow.Export.PDF.NativePDF.ImageFormat = 0

this.Object.DataWindow.Export.PDF.NativePDF.PDFStandard = 0

 

A picture where you can see how bad it looks the image:

Hi Pau,

 

Can you let us know the format type of the embedded images used in your datawindow? Is it BMP?

If not, and if you are using the JPG format type, please set ImageFormat=1 and try it again.

If you are using the PNG format type, please set ImageFormat=2 and try it again.

You can refer to the following link for more details:

https://docs.appeon.com/pb2019r2/datawindow_reference/ch03s03.html#XREF_19761_Export_PDF_NativePDF_ImageFormat

BTW, can you confirm whether John’s suggestion works for you?

 "I've had great success using JPG's. Try converting the graphic to a JPG and use ImageFormat=1."

If the above info is not helpful kindly please report this problem to our ticket system:https://www.appeon.com/standardsupport/newbug so it can be properly received and tracked. 

Please also provide a sample test case when you submit it to the ticket system.

 

Regards,

Greetings, Pau - 

I've had great success using JPG's. Try converting the graphic to a JPG and use ImageFormat=1.

Do you have a test/sample app that uses JPG you could post? I'd very much like to see what you are trying to accomplish that does not work because, as I stated above, we experience no image quality concerns using JPG's with NativePDF when ImageFormat=1.

Hi John,

I tried to use JPG image and Image Format=1 and it works well, but I need the PNG format because all our application images are PNG files.
