L_UINT uFlags;

flags

Warps the image around a 3D spherical shape.

Parameter Description
nValue Amount of stretching where :
  Positive values: stretch the central pixels toward the edges.
  Negative values: stretch the pixels toward the Center.
  Valid values range is 500 to 500.
CenterPt POINT structure that contains the center of the sphere.
crFill The COLORREF value that specifies the fill color for any exposed areas.
uFlags Flags that indicate how to handle exposed areas outside the sphere and inside the sphere. You can use a bitwise OR (|) to specify one flag from each group.
  The following are the flags that indicate how to handle exposed areas outside the sphere:
  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 exposed areas inside the sphere:
  Value Meaning
  FILL_ROT [0x0000] Rotate the image inside the sphere pattern.
  FILL_WOUTROT [0x0010] Fill exposed sphere pattern center as selected from exposed area process type flag.
  This flag is ignored if the nValue is negative.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

This function will warp the image as a 3D spherical shape around the specified CenterPt. The center point must be defined inside the bitmap or inside the region, if the bitmap has a region.

If the bitmap has a region, the effect will be applied on the region only.

This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.

This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.

This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
