<ul></ul><p>For me icons for raster image are not too useful.</p>
<p>Why should QGIS draw an icon that represent a, for example, 5000x5000 pixel raster in a space of 16x16?</p>
<p>QGIS should use a simple icons for all rasters...</p> QGIS Application - Bug report #2876: bring back raster legend iconshttps://issues.qgis.org/issues/2876?journal_id=226312010-07-08T04:58:42ZGiovanni Manghigiovanni.manghi@gmail.com

<p>because when you do raster analisys your rasters (not normal orthophotomaps or militar maps) normally have very different colormaps and with icons they are EASILY identified in the legend.</p> QGIS Application - Bug report #2876: bring back raster legend iconshttps://issues.qgis.org/issues/2876?journal_id=226322010-07-08T05:19:34ZWilliam Kyngesburyekyngchaos@kyngchaos.com
<ul></ul><p>Here's my notes, for the record:</p>
<p>It seems to only affects rasters without overviews. I did a test with a single 1 GiB JP2 and it generates the legend icon nearly instantaneously. A 1.3 GiB tiff without overviews takes a long time, yet the same with overviews is fast. A 200MiB tiff without overviews has a noticable delay, but it's not horrible.</p>
<p>Though the original issue is a small 14MiB vrt with jp2 images, zooming and panning are not affected. Maybe there's something else with a vrt that slows down the legend generation?</p> QGIS Application - Bug report #2876: bring back raster legend iconshttps://issues.qgis.org/issues/2876?journal_id=226332010-07-11T01:13:13ZMarco Hugentoblermarco.hugentobler@sourcepole.ch
<ul><li><strong>Resolution</strong> set to <i>fixed</i></li><li><strong>Status</strong> changed from <i>Open</i> to <i>Closed</i></li></ul><p>Ok, there is now an option to disable raster icons in case of performance problems (btw., those icons are 32x32 )</p>
