PDF jpeg of page not producing image correctly

Aspose.PDF Product Family
1

Hi, A PDF page that I am creating an image of, using Aspose.Pdf.Devices.JpegDevice, is not producing the correct image.

The PDF contains a transparent gradient above an image, I think the transparent gradient is not recognised and when rendering the image it shows a none transparent color gradient and thus hides the image below, making the bottom of the page not look like the original PDF.
Is this a know issue with Aspose.PDF for .Net?

Hello,

I’ve got the same problem with the recent version (17.4.0).

Source: https://viewer.li/image/GetContentById/1610

Created image: https://viewer.li/image/GetPreviewById/1610

You seen on top the transparent background inside the PDF file, the image doesn’t have the transparency.

Please let me know whether this issue has been solved after 4 years.

Regards

Herbert

Hi Asad, Is there any update on this issue.

Additionally I have one more query, In my case I am using a radial gradient rectangle(radial_grad.zip), it seems to be rendering in the PDF but not when I convert the pdf to a png/jpg image using JpegDevice/PngDevice.

Could you please update on an ETA this would be fixed.

Your help is much appreciated.
