Thanks for the mail Alan.
I am programming it in Cpp and using Qt architechture . I will try with a
new raster band and try to make it as a mask with forecfully assiging a
value to it.
data = (uchar *) CPLMalloc(sizeof(uchar)*width*height*bytesPerPixel);
poBandR->RasterIO(GF_Read, xOff, yO
Hi ,
I have found the solution myself.
Below is the piece of code for polygonizing the raster.
Yet there is another problem i am facing. I am unable to create a mask band
for a particular pixel value.I understand that could be done using
thresholding. But I did not find any method for that in GDA
