GXGetRotatedGSPixMapWidthHeight

Gives the width and height of the bounding box large enough to accomodate the pixmap after rotation.

    void GXGetRotatedGSPixMapWidthHeight (
      Int32*         dWidth,
      Int32*         dHeight,
      double         angle,
      const GSRect*  sClip,
      const GSRect*  dClip,
      Int32*         f0h,
      Int32*         f0v
    );

Parameters

dWidth

In: the width of the original pixmap. Out: the width of the rotated pixmap.

dHeight

In: the height of the original pixmap. Out: the height of the rotated pixmap.

angle

The angle of the rotation.

sClip

A cliprect of the original pixmap.

dClip

The cliprect of the rotated pixmap.

f0h

The x coordinate of the bottom left vertex of the original pixmap on the rotated pixmap.

f0v

The y coordinate of the bottom left vertex of the original pixmap on the rotated pixmap.

Remarks

When you rotate a rectangle its bounding rectangle will be larger, this function helps to determine its new dimensions. The coordinates of the original pixmap in the rotated helps to align the new pixmap position such way its anchor point remain fixed.
