[Gdal-dev] Does GDAL1.4.1 support vector quantization

[Alison Luo]

Sample NITF file U_3058b.ntf from
ftp://ftp.remotesensing.org/gdal/data/nitf/nitf2.0/
has vector quantization compression. The image has 1
block of size 1536x1536. I used RasterIO method in
GDALDataset class to get raw image data as follows:

imgData->RasterIO(GF_READ,0,0,1536,1536,pData,1536,1536,GDT_Byte,1,NULL,0,0,0);

But the returned data in buffer pData is all wrong. Is
it because GDAL does not support vector quantization
compression or I did not use RasterIO correctly?

Thanks,
Alison
