[Bug 58217] New: support alpha channel on solid colors (fill, line,
text)
https://bz.apache.org/bugzilla/show_bug.cgi?id=58217
Bug ID: 58217
Summary: support alpha channel on solid colors (fill, line,
text)
Product: POI
Version: 3.13-dev
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P2
Component: XSLF
Assignee: dev@poi.apache.org
Reporter: Mark.Olesen@gmx.net
Created attachment 32976
--> https://bz.apache.org/bugzilla/attachment.cgi?id=32976&action=edit
patch with proposed changes
Was previously missing.
The implementation takes the alpha channel from the Java Color. This is
probably less clutter than adding an additional setAlpha method.
Added use to Tutorial3.
NB: the alpha channel only works for setters, not getters.

Normal HSSF colours don't have an alpha channel. Extended HSSF colours do, as
do non-theme XSSF colours
If you haven't already, it might be worth you looking at how it works (or
doesn't...) for SpreadSheet extended colours / xssf colours, then see if there
are any ideas from there that can be used in the slideshow side / good ideas
from the slideshow side which can go to spreadsheet

I did take a look some of the spreadsheet implementation ... quite hairy.
I'd guess the first step would be to at least commonalize some of the hslf/xslf
colour handling.

Thanks for your patch.
Applied and adapted via r1745101
Instead of the static method setFillColor, I've decided to apply the color
change via a XSLFColor instance
