Bug ID: 96196
Summary: Exporting a chart in PNG does not preserve
transparency or absence of area fill
Product: LibreOffice
Version: 4.4.6.3 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Chart

file to test bug
When exporting a chart that has no background area fill or some transparency as
PNG, the resulting file does not have (100% or partial) transparency conserved,
but rather a fixed colour that is the result of the addition of the (more or
less) transparent + a white background.
Steps to reproduce:
- create a chart with some random data
- select background of chart, right click, "format chat area"
- either remove the colour in "Area" or set a transparency level in
"Transparency"
- right click on the whole chart, "export as image...", choose PNG format, give
a name, save
Expected result:
- Transparency or absence of background is conserved
Actual result:
- If colour was removed, the result is a white background
- If transparency was set on a colour, result is the addition of the partial
transparency on a white background
Attached spreadsheet allows to test exporting the charts straight away.
