Parameter

Description

uAmplitude

Wave’s magnitude. The values range from 1 to the length of the image's diagonal.

uWaveLen

Value that represents the wave length, if DIS_PER is set in the uFlags parameter. Possible values range from 1 – 100 and give the wavelength as a percentage of the bitmap dimensions. If DIS_FRQ is set in uFlags, this value is the number of repeated waves.

nAngle

Wave’s rotation angle in hundredths of degrees. The valid range is from –18000 to 18000 (The value in degrees is nAngle divided by 100).

uHorzFact

Size of the horizontal wave, given as a percentage. The valid range is from 0 to 100.

uVertFact

Size of the vertical wave, given as a percentage. The valid range is from 0 to 100.

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, the type of information in the uWaveLength parameter and the wave type. 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:

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 type of information in the uWaveLen parameter:

Value

Meaning

DIS_PER

[0x0000] The value in uWaveLen is a wavelength given as a percent of the bitmap dimensions. If this value is used, the valid range of uWaveLen is from 0 to 100.

DIS_FRQ

[0x0010] The value in uWaveLen is the frequency, or the number of times the wave repeats.

The following are the flags that indicate the wave type:

Value

Meaning

WV_SIN

[0x0000] The wave is a sinusoidal wave.

WV_COS

[0x0100] The wave is a sinusoidal wave shifted by 90 degrees.

WV_SQUARE

[0x0200] The wave is a square wave.

WV_TRIANG

[0x0300] The wave is a triangular wave.

SUCCESS

The function was successful.
