GETSCALINGFACTOR

The GETSCALINGFACTOR escape retrieves the scaling factors for the x and y axes of a printing device. For each scaling factor, the escape copies an exponent of two to the location pointed to by the lpFactors parameter. For example, the value three is copied to lpFactors for a scaling factor of eight.

Scaling factors are used by printing devices that cannot provide the same
resolution as the device resolution. This escape communicates to GDI the
factor by which it needs to stretch bitmaps when sending them to the printer.

Parameters

lpDevice

Points to a PDEVICE structure specifying the destination device.

lpFactors

Points to a POINT structure that receives the horizontal and vertical scaling factors in the x and y members, respectively. The POINT structure has the following form:

typedef struct tagPOINT {

short x;

short y;

} POINT;

Return Value

The return value is positive if the escape is successful. Otherwise, it is negative.
