Hi,
Thanks for the quick reply Frank.

Hi,
I'm using the GDALRasterBand::RasterIO() function to write a buffer
of C/C++ float types to a raster band of data type
GDALDataType::GDT_Float32. I assumed that this conversion would not
be problem since the size of a C/C++ float is also 32 bits, but I
wanted to be sure. If the conversion will be problematic, how would I
resolve the issue (ex: a potential cast maybe).
Adeel,
There is no problem. The GDT_Float32 enumeration value refers to the
normal 32bit system "float" type in C/C++.
I would add that you should expect, and provide float's in native
machine order. GDAL will take care of byte swapping during io if
needed.
Best regards,
