Generating quicklook for an image with 100 bands is very slow
Mantis Issue 174, reported by echristophe, assigned to jmalik, created: 2010-06-15
Generating quicklook for an image with 100 bands is very slow even if only one band is chosen for the display. The resampling should process only on the required bands.
To reproduce:
- generate an image with 100 features from a spot full scene image (about 20GB)
- open and display in Monteverdi
The navigation is very slow: 2min waiting when trying to move in the image. Even if the order is bsq: all the pixels to display are contiguous on disk.
