Subject: [Xerte] jpgs degrading - is this a new phenomenon?</p>
<div>
<p>This seems weird but yesterday I was demonstrating a learning object to some colleagues I was working with and I noticed that the images which I’d carefully crafted to be crisp and sharp and fit the available space were looking pixellated and ugly with lots
of jpegy artefacts (like when you save a jpeg at too coarse a setting and get fuzz around lines etc). The originals I uploaded are much higher quality.
</p>
<p> </p>
<p><img border="0" width="630" height="418" id="_x0000_i1026" src="cid:image001.png@01CCD2DC.82D09E90"></p>
<p> </p>
<p> </p>
<p>However no such degradation is apparent with PNG files as shown below: (as before the original is at the bottom and the Xerte rendered version at the top). In this case the quality is indistinguishable.</p>
<p><img border="0" width="396" height="422" id="_x0000_i1027" src="cid:image002.png@01CCD2DC.82D09E90"></p>
<p> </p>
<p> </p>
<p>Is something taking place in the upload that degrades the jpgs or how is this oddity explained. For the short term I can use PNGs rather than JPGs but it introduces an extra work layer and It doesn’t help the dozens of LOs that used to look crisp and now
look fuzzy. Any suggestions gratefully received!</p>
