lFlags
Flags that indicate how to handle exposed areas, the type of information in the iWaveLength 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 iWaveLen parameter:
|
Value |
Meaning |
|
DIS_PER |
[0x0000] The value in iWaveLen is a wavelength given as a percent of the bitmap dimensions. If this value is used, the valid range of iWaveLen is from 0 to 100. |
|
DIS_FRQ |
[0x0010] The value in iWaveLen 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. |
