[jira] [Commented] (WHIMSY-284) Error converting PNG to PDF

    [ https://issues.apache.org/jira/browse/WHIMSY-284?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16897505#comment-16897505 ] 

Sam Ruby commented on WHIMSY-284:
---------------------------------

I tried converting the image locally using img2pdf, and got the following:

$ img2pdf Screen\ Shot\ 2019-07-28\ at\ 13.43.25.png 
WARNING:root:Image contains transparency which cannot be retained in PDF.
WARNING:root:img2pdf will not perform a lossy operation.
WARNING:root:You can remove the alpha channel using imagemagick:
WARNING:root:  $ convert input.png -background white -alpha remove -alpha off output.png
ERROR:root:error: Refusing to work on images with alpha channel

Previously, we used imagemagick's convert, and that works fine on this image.
