[Gdal-dev] gdal_translate versus mrsiddecode

[Chris G. Nicholas]

Just checked out the latest/greatest CVS snapshot, as well as the same for MrSid DSDK, and not sure why, but mrsiddecode is *_way_* faster for some simple cases; I'm just trying to make thumbnails of some monster images we have sitting around, and doing some simple non-geographic extracts.

Something like:

gdal_translate -of jpeg -outsize 500 500 /data/f04/contentapu1/apu01_2ft_aus_2.sid /tmp/foo.jpg

Input file size is 188933, 47333

goes out to lunch for several minutes. mrsiddecode does the equivalent in under a second. 

Am I doing something wrong?

thanks in advance!
