|Summary||0009158: broken gradients and transparencies in alternative PDF viewers|
|Description||broken gradients and transparencies in alternative PDF viewers|
|Steps To Reproduce||- create PDF with gradients|
- create PDF with transparency gradient
- see it in for example evince
1, it was created directly by Scribus and exported to PDF
2, first picture was exported like svg and loaded into Inkscape, exported to PDF
Both are PDF 1-4, so transparency should be supported.
EVINCE: You can see that there is something wrong. There is additional white line and transparency is missing.
OKULAR and Xpdf: There is additional black line in transparency.
Sorry if this is viewer's problem. It seems to me as a Scribus issue because Inkscape has no problem with any of this viewers.

||Evince has no proper transparency support and this is one of reason amongst others we strictly dis-recommend its usage for viewing pdf produced by Scribus.|
||ok, but why Inkscape PDF display this correctly?|
||If Inkscape somehow merges layers, Scribus could do too as a option.|
||This would be very useful feature for printing too.|
Inkscape uses cairo library for its pdf output, and does not output pdf by itself. Cairo is able to flatten transparency in rgb mode, but it has no color management support, no cmyk support and no spot color support, which means its transparency flattening is not conformant to pdf specs and consequently not useable by scribus...
Transparency flattener is already the object of a feature request (0000876)
||I understand now. Personally this functionality has high priority for me. You can close this as a duplicate.|
