PdfProcessing: NETStandard: Add support for exporting PNG images
Currently adding an Image content element with ImageSource instantiated with a PNG file format leads to NotSupportedException: 'Can not export other than Jpeg and Jpeg2000 and ImageQuality different than High', when exporting the document.

Support for adding PNG images and exporting to PDF should be implemented for PdfProcessing for .NET Standard scenario.

Hello Keith,

With the current implementation of the .NET Standard version of the PdfProcessing library when importing images with transparency (alpha channel) the transparency is lost. We have a feature request logged in our backlog to provide support for inserting transparent images: PdfProcessing: Provide support for inserting transparent images in Net Standard.

I want to apologize for the inconvenience this missing functionality might be causing you, so please, make sure to cast your vote for its implementation as well as subscribe to the task by clicking the Follow button so you can receive updates when its status changes.

I'm confused.  This is marked completed, but according to the documentation Cross-Platform it is not yet.

I need to add some PNGs particularly due to transparent settings.  Or, I would take a suggestion on how to map the transparent part of ImageBlock to match the underlying color of a document so that the Jpeg appears to be transparent.

Hi Adithya,

Could you tell us what are the image formats contained in the documents you want to process using the PdfProcessing library, so we can add them to the feature request?
