globalmapper.GetPixelColorRow¶
- globalmapper.GetPixelColorRow(GM_LayerHandle_t32 aLayer, sint32 aRow, COLORREF aInvalidVal) GM_Error_t32, COLORREF [source]¶
Retrieves the color values for an entire row of the provided layer. If any pixels don’t have valid values they will be replaced by aInvalidVal. This function is much faster than individually getting the color value for individual pixels using the GetPixelColor function, so use this to access large portions of a loaded layer.
