完了Support for PNG with alpha channel in pdf export
0%
説明
The /vendor/plugins/rfpdf/tcpdf.rb, port of "FPDF":http://www.fpdf.org, not work with png with alpha channel. The latest version of www.fpdf.org (1.7.1) is now able to do that, and an update to the ported class, will be really appreciated.

I have written a patch for r12228 by porting https://code.google.com/p/pyfpdf/source/detail?r=6d269f7474c6
However, interlacing and 16-bit depth are not supported yet.

Here is a backported plugin by monkey patching: https://github.com/t-yuki/redmine_pdf_export_backports

Has the patch provided by Yukinari been validated with newer versions of Redmine? We are on 2.3.4 stable. Thank you for helping to address this 16-bit PNG issue.

Applied the patch in my test environment but saw no change. I loaded the Redmine PDF Export Backports plugin which granted the ability to export as HTML but PDF is still unable to render. Any ideas on how to resolve? Thank you.

**Update**
I have loaded the plugin provided by Yukinari https://github.com/t-yuki/redmine_pdf_export_backports and was able to resolve the PDF export issue. In order to export PDF's, the short syntax of declaring an image must be used. For example:
"!myimage.png!" *without quotes*
We were using the long syntax of declaring the entire URL string. Adjusting the syntax allowed images to display properly in PDF exports.
Thank you Yukinari for your help with this.

Fixed by #17570.
