Image Transparency Issue While Exporting To PDF - ArcGIS Pro

[SeanFadum1]

Hi,

When I apply a transparency to a raster image (ie. an airphoto) and export my layout in ArcGIS Pro to PDF, strange lines appear in the image (almost like the software is tiling it).  If I remove the transparency, then the export is fine. I have tried adjusting the DPI during the export and printing directly to PDF, with no luck.

Has anyone else had this issue... and if so is there a fix?  I am using ArcGIS Pro 2.0.1.

Thanks,

Sean

That's my fault, I was just cleaning up some old issue paperwork as part of finishing this release. 

But, I think you may have missed a detail :):

After a lot of design/prototyping with our senior output and rasterizer developers, and extensive testing and tuning of the mitigation strategy, we have exposed an option to _work around_ the limitations of adobe acrobat in displaying adjacent transparent tiles of content, by attempting to export a SINGLE tile as long as we can allocate enough memory to do so up to a reasonable limit. 

TL;DR: A new option mentioned is scheduled to be available in the next release of ArcGIS Pro (3.5) that mitigates the artifact for all repro cases (former bug reports and issues from Pro 1.x to now) that we found in our research on the background of this bug, as long sufficient free memory is available to do so.   And unlike "Export As Image" it doesn't lose the layers in your map.
