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).

Gary

PluginBasedJPEGReadWriter anomaly
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
