zmap_GetScanlineArray

Get the pointer to the array of scanlines of a map.

void** zmap_GetScanlineArray(ZMAP hMap);

A null pointer if:

• The map is not initialised, or;
• The map is a mosaic (See zmap_GetMosaicFlag), or;
• The map is allocated as a contiguous block of memory (See zmap_IsContiguous), or;
• An error occurred.

Otherwise, the return value is the pointer to an array of pointers to the scanlines. The length of the array is given by zmap_GetHeight. Each member of the scanline array is a pointer to the first pixel of each scanline. The length of each scanline is given by zmap_GetWidth, and the type and size of the pixel data in the scanlines may be retrieved from zmap_GetMapType and zmap_GetPixelSize.

None.
