2) When I read an image through ReadBlock() i had to allocate some
memory
and pass it in the function. Is there some way that i get the image data
stored in GDALRasterBlock directly without passing my own allocated

you are
going to need to modify the input data pre-processing.

Hi,
I have few questions regarding GDAL tiling and overviews.
1) Is there any In build direct function in GDAL from where i can set the
size of the tiles(raster block size).
2)I an facing an strange situation. I have an TIFF image, and I am trying
to read it block by block using ReadBlock().
Thanks for your quick reply,
I dont want to use GDALRasterIO, I dont want to allocate memory of size
equal that of image or ROI, i want to make use of tiling as much as
possible. Can you provide more detail on how to create tiles tiff files by
default.

Hi,
I have a loaded an raster image using GDAL, and i want to provide a drawing
tool using which user can draw an irregular shape on the raster image and
then save the shape and the enclosing pixels in a vector format for future
use. Can any one tell me how to do this in GDAL/OGR?
Thanks and
Hi all,
How exactly does caching work in gdal. If I have 2 or more images opened
simultaneously in gdal, does gdal consider the tiles(or scanlines)
belonging to different images separately or does it keeps a common set, can
any body explain how it is done in gdal.
Thanks and regards,
Akshay
