NONE —Do not convert RGB. 10 Python Libraries for GIS and Mapping Python libraries are the ultimate extension in GIS because it allows you to boost its core functionality. Map projections - or Coordinate Reference System (CRS) - often cause a lot of frustration when working with GIS data. If we're talking about RGB TIFFs then there are some things "baked in" that are irreversible in the sense that the TIFF can not be "deconstructed" to produce the exact same data as was contained in the source file. If you have ever worried or wondered about the future of PIL, please stop. If you already have this array, it means it has nothing to do with TIFF, the data is already unpacked from TIFF, or this is not TIFF at all. However, I never tried this. imread('abc. As scanners. imread(filename[, flags])) which specifies the colour type of the loaded image cf. Presume LSM stores uncompressed images contiguously per page. py file contains a pil_to_np_rgb() function that converts a PIL Image to a 3-dimensional NumPy array in RGB format.
