ZeeImage - ZGM_SETDIVISOR

ZeeImage Control Message

ZGM_SETDIVISOR

An application sends a ZGM_SETDIVISOR to manage the resolution of images when loaded with ZIM_LOADIMAGE.

ZGM_SETDIVISOR
wParam = (WPARAM)(int) iDivisor;           //Divisor to use when loading image.
lParam = 0;                                //Not Used.  Set to 0.

Parameters

iDivisor: The value of wParam. An integer divisor to use when loading the image.
lParam: The value of lParam. Not used. Set to 0.

Return Values

This message does not return a value.

Example


SendMessage(himage,ZGM_SETDIVISOR,2,0);

Note:

The divisor is a "sticky" control variable that determines the resolution of the loaded image. The control defaults to a divisor value of 1. If the image being loaded has a resolution of 1600x900, setting the divisor to 2 before loading the image will load the image with a resolution of 800x450. This can be used to save memory when a high resolution image will only be displayed in a relatively small area on the screen. This can also prevent you from having to manually resize images that are in too high of resolution for your application.
