Well, I get the same result when loading any JPEG (Windows VM 4.0.2).
Easiest to just drag a JPEG image into the Pharo window and choose "open
graphic in window".
Distinctive top-left pixel (actually transparent now I investigate further)
along with bad edge.
To compare, change
PluginBasedJPEGReadWriter>>understandsImageFormat
to return false (will then use original JPEGReadWriter).

Hi Gary,

Hi all.
Iv'e noticed a slight anomaly with the PluginBasedJPEGReadWriter when
reading jpeg files (at least on Windows platforms).
The upper left pixel appears to be white and the whole left-hand column of
pixels have anomalous values.
COuld you help me reproduce this case exactly? We had a crash a few weeks
ago in te JPEG plugin but have not been able to find the data that reproduced
it. Looks like you have a case which causes the plugin to behave incorrectly.
So how do I run the plygin case and the non-plugin case side-by-side?
TIA
Eliot
Attached, for reference, are screenshots when using the plugin, the
original Smalltalk implementation and Windows picture viewer.
Regards, Gary
