Wraps the bitmap onto a 3D plane shaped by pnCurve. This function is available in the Raster Pro and above toolkits.
Parameter |
Description |
|
pnCurve |
Array of integers that represent surface shape values. Valid values for each element in the pnCurve array range between –1000 and 1000. Positive values mean the curve is concave in and negative values mean the curve is concave out. The values in this array are divided internally by 1000. |
|
uCurveSize |
Size of the pnCurve array. |
|
uScale |
Factor used to multiply the various amplitude values in the pnCurve array. Each value in the pnCurve array is multiplied by this factor. For example, if you want to double the size of the amplitude values, use a uScale value of 2; to triple the amplitudes values, use a uScale value of 3, etc. The top practical limit for this parameter is the width and height of pBitmap. |
|
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 exposed areas and the plane along which to stretch the pixels. You can use a bit wise OR (|) to specify one flag from each group. |
|
|
The following are the flags that indicate how to handle 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 the plane in which the stretching is to occur: |
|
|
Value |
Meaning |
|
FPB_HORZ |
[0x0010] Stretch the pixels along the vertical plane. |
|
FPB_VERT |
[0x0020] Stretch the pixels along the horizontal plane. |
|
FPB_VRHZ |
[0x0030] Stretch the pixels along the horizontal and vertical plane. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
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.
To update a status bar or detect a user interrupt during execution of this function, refer to LBase::EnableStatusCallback.
For an example, the following figure shows a bitmap before the effect is applied.
The following figure shows the same bitmap after the effect has been applied.
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.
