Description
This pure-python application creates a 256 colors image of a 2D HDF4 SDS. It supports different colormaps, min/max thresholding, scaling, fill value filtering…
Many output image formats are also supported.
Classes in this package can also be called as python libraries in your own programs :
- hdf2img.py : processor for building an image from a HDF dataset
- data2img.py : processor for building an image from a numpy array
Limitation
- Only 2D datasets are currently supported
Usage
Usage: hdf2img [options]<infile> HDF4 input file <sds> Name of the SDS to be drawn Options: -h, --help show this help message and exit -o OUTFILE, --output=OUTFILE The output file name. The output image file format will be based on the file extension. If not given, <input-dir>/<input-file-without- extension>_<sds>.png will be used -c COLORMAP, --colormap=COLORMAP The colormap (ocean,bw_linear,red_temp,blue,blue_red,r ainbow,rainbow_white,lidar_nasa) to use or the colormap file name -S SCALE, --scale=SCALE The type of scale to use : linear(default), log -m THRESHOLD_MIN, --threshold_min=THRESHOLD_MIN The values smaller than threshold_min will be clipped to it -n THRESHOLD_MAX, --threshold_max=THRESHOLD_MAX The values greater than threshold_min will be clipped to it -w INVALID, --invalid=INVALID The invalid fill value (optional) -u INVALID_IDX, --invalid_idx=INVALID_IDX The invalid fill value colormap index (optional) -v, --verbose Print out processing informations -d, --is_palette_index Palette values are a index. -x, --overwrite Overwrite the output file if already existent
