pkdumpimg - program to dump image content to ASCII or STDOUT
Contents
Description
pkdumpimg dumps the content of a raster dataset to (standard) output (screen or filename). The default
is to dump the output in matrix format. Use -of line to dump each pixel value on a separate line, preβ
ceded by its position (x and y value). You can specify a bounding box to dump with either the extent of
an OGR vector dataset or via the options -ulx-uly-lrx and -lry.
Example
We create a 5x5 raster dataset containing all 0 values except for its center (value=1)
catinput.txt
0 0 0 0 0
0 0 0 0 0
0 0 1 0 0
0 0 0 0 0
0 0 0 0 0
