zmap_GetMipmapResStep

zmap_GetMipmapResStep

Description

Get the resolution step factor between successive mipmaps for a given map.

Files

Declaration	`Zeolite.h`
Implementation	`Zeolite.cpp`

Function prototype

long zmap_GetMipmapResStep(ZMAP hMap);

Arguments

Name	Type	Comment
hMap	`ZMAP`	A handle to a map variable, the mipmap resolution step factor of which is to be retrieved.

Return value

An integer greater than one if mipmaps have been initialised. Otherwise, zero is returned.

As an example; if a value of 4 is returned by this function, it means that the first mipmap level that can be accessed by zmap_GetMipmapLevel is 4, the next is 16, after that is 64, and so on up to the maximum mipmap level given by zmap_GetMipmapMaxLevel.
