[gdal-dev] Transform pixel coordinates

[Artur Bercik]

Dear GDAL users

I have a raster image of 406 lines and 270 samples with 5km pixel size. The
center coordinates (lats and lons in degrees in GCS) of upper left pixel,
and the center coordinates (lats and lons in degrees in GCS) of the lower
right pixel  are given, how can I calculate the coordinates of upper left
corner (ulx and uly) and the coordinates of lower right corner (lrx and
lry)?


upperLeftCentralX, upperLeftCentralY = 150.1234, 50.1234

pixelWidth, pixelHeight = 5, 5

cols, rows = 270, 406

upperLeftX, upperLeftY = ?, ?

Thanks in the advance.

Artur
