@HamedAlemo I'm pretty sure this is a BUG with the GDAL GDALCreateCopy
method. you might want to open an issue in the GDAL or rasterio repo
from rasterio.io import MemoryFile
from rasterio.shutil import copy
from affine import Affine
profile = {
"driver": "GTiff",
"count": 1,
"dtype": "uint8",
"height": 512,
"width": 512,
"crs": "epsg:4326",
"transform": Affine(0.703125, 0.0, -180.0, 0.0, -0.3515625, 90.0),
}
with MemoryFile() as memfile_int:
with memfile_int.open(**profile) as src:
src.write_colormap(1, {0: (255, 0, 0, 255), 1: (0, 0, 0, 0)})
print(min(src.colormap(1)), max(src.colormap(1)))
out_profile = profile
with MemoryFile() as memfile_out:
copy(src, memfile_out.name, **profile)
with memfile_out.open() as dst:
print(min(dst.colormap(1)), max(dst.colormap(1)))
0 1
0 255
