garrettsickles / hgt2png Goto Github PK

As you already pointed out, this program maps the color #000000 to the lowest point of the HGT file and #FFFFFF to the highest point. This is certainly useful, but if you want to combine multiple HGT images with different height ranges, this feature becomes a problem.
So, could you add a command-line argument that allows you to specify whether you want the PNG to use colors depending on the height range of the HGT file (grayscale) or to use globally defined colors which are identical between the converted files? For example, the color value #7F7F7F (medium gray) could be 0 meters above sea level, so would #7F7F80 be 1 meter above sea level and so on. When using non-grayscale colors, every height from the Mariana Trench to the summit of Mount Everest should be covered.
Since I have no clue about C++ and was hardly able to build this program, I can't implement it myself. Thank you for your help!

Hello, I'm trying to build your program, but get this error. Seems like it's not supported on Windows. Is there a way to make it work?
