Description Tomáš 2018-04-09 11:12:17 UTC
Color of font is not set properly by call to method XSSFFont.setColor(XSSFColor).

[styles.xml] It sets 'rgb' attribute of 'color' element without an alpha channel but 'rgb' attribute is of type ST_UnsignedIntHex which has length 4 (ARGB in hexadecimal format).

[XSSFFont.java] Guess the problem is in XSSFFont's method setColor(XSSFColor) at the following line:


where a call to getRGB() should be replaced by getARGB().

This sounds like a duplicate of #54373 or at least it sounds closely related.

We improved support for transparency/alpha-channel via r1907106 and r1907105 which hopefully also solves this issue.
