I have a problem when producing overviews in a jpeg compressed tiff.with
After my basic image is produced, with the GeoTIFF driver, I call
overviewlist is 2,4,8,16,32,64,128
(It's a VB.NET 2010 app.)
I get this message: GetBlockRef failed at X block offset 1, Y block offset 0
It's the same in my program as in GdalOverviews.
The basic image is made line by line with RGB bands.
The image is 7588 by 5492 pixels.
I use PHOTOMETRIC=YCBCR,PROFILE=GEOTIFF,COMPRESS=JPEG,TILED=YES
If I add BIGTIFF=YES when creating it, the overviews generation seem to
work, but the colors are all messed up in the overviews
