Parameter

Description

pBitmap

Pointer to the bitmap handle that references the bitmap on which to apply the effect.

nValue

Amount of stretching, where positive values stretch the pixels toward edges, and negative values stretch the pixels toward the center. Possible values are range in between -500 and 500.

CenterPt

A POINT structure that contains the center of the arc. This is ignored when either BND_HORZ or BND_VERT is set in the uFlags parameter.

crFill

The COLORREF value that specifies the fill color for any exposed areas. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.

uFlags

Flags that indicate how to handle peripherally exposed areas, how to handle centrally exposed areas and the type of bending. You can use a bitwise OR (|) to specify one flag from each group.

The following are the flags that indicate how to handle peripherally exposed areas:

Value

Meaning

FILL_CLR

[0x0000] Fill any exposed areas with crFill.

FILL_RPT

[0x0001] Stretch the image edges to fill the exposed area.

FILL_NOCHG

[0x0002] Leave the exposed area as is, without changing it.

The following are the flags that indicate how to handle an exposed center:

Value

Meaning

FILL_ROT

[0x0000] Rotate the image inside the arc pattern.

FILL_WOUTROT

[0x0010] Fill the exposed center as you would any other exposed area. This is determined by setting the FILL_CLR, FILL_RPT or FILL_NOCHG flags.

This flag is ignored if the nValue is negative.

The following are the flags that indicate how the bitmap is bent:

Value

Meaning

BND_NORM

[0x0000] Stretch the image along the vertical and horizontal planes.

BND_HORZ

[0x0100] Stretch the image along the horizontal plane.

BND_VERT

[0x0200] Stretch the image along the vertical plane.

SUCCESS

The function was successful.
