Erases a rounded rectangle.

void EraseRoundRect (
    const Rect *r, 
    SInt16 ovalWidth, 
    SInt16 ovalHeight
);

Parameter descriptions

r

The rectangle that defines the rounded rectangle’s boundaries.

ovalWidth

The width of the oval defining the rounded corner.

ovalHeight

The height of the oval defining the rounded corner.

DISCUSSION

Using the patCopy pattern mode, the EraseRoundRect function draws the interior of the rounded rectangle bounded by the rectangle that you specify in the r parameter with the background pattern of the current graphics port. This effectively erases the rounded rectangle. Use the ovalWidth and ovalHeight parameters to specify the diameters of curvature for the corners of the rounded rectangle.

This function leaves the location of the graphics pen unchanged.

SPECIAL CONSIDERATIONS

The EraseRoundRect function may move or purge memory blocks in the application; do not call this function at interrupt time.

AVAILABILITY
