[jira] [Commented] (PDFBOX-2067) Error creating JPEG image with SMask

    [ https://issues.apache.org/jira/browse/PDFBOX-2067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13993982#comment-13993982 ] 

Tilman Hausherr commented on PDFBOX-2067:
-----------------------------------------

I added code to throw an exception for BITMASK transparency (see PDFBOX-2057) because it makes no sense to encode a binary mask in jpeg. I moved getAlphaImage() up one level because it is only used for jpeg; I optimized getColorImage() with ColorConvertOp instead of an xy-loop. All in rev 1593630 for the trunk.
