常用示例
Apply Mercator projection
pnmmercator [input.pnm] > [output.pnm]
Inverse projection
pnmmercator -inverse [input.pnm] > [output.pnm]
说明
pnmmercator converts PNM images between equirectangular (plate carrée) and Mercator map projections. The input image is treated as a map where rows correspond to latitude lines and columns to longitude lines. The forward transform converts equirectangular to Mercator projection, stretching areas near the poles. The -inverse option reverses this, converting from Mercator back to equirectangular. Part of the Netpbm toolkit.
参数
- -inverse
- Convert from Mercator to equirectangular.
