typedef struct _RADIALWAVEDLGPARAMS
} RADIALWAVEDLGPARAMS, * LPRADIALWAVEDLGPARAMS;
The RADIALWAVEDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImageEffect::DoModalRadialWave function. After the user closes the dialog box, this structure is updated with information about the user's selections.
Size of this structure, in bytes. Use the sizeof operator to calculate this value.
Pointer to the bitmap handle that references the bitmap used for preview or processing.
Flag that indicates the initial zoom level for previewing the image. Possible values are:
|TRUE||Set the initial zoom level to "Zoom to fit".|
|FALSE||Set the initial zoom level to "Normal (1:1)".|
Magnitude of the wave. Valid values range from 0 to 100.
Value that represents the wave length, if DIS_PER is set in the uRadialWaveFlags member. If DIS_FRQ is set in uRadialWaveFlags, this value is the number of repeated waves. Possible values range from 0 to 100.
Wave phase shift, in hundredths of degrees. The valid range is from −36000 to 36000 (The value in degrees is nPhase divided by 100).
POINT structure that contains the point from which the wave radiates. The center point must be defined inside the bitmap, or inside the region, if the bitmap has a region.
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.
Flags that indicate how to handle exposed areas and what type of information is in the uWaveLen parameter. You can use a bitwise OR (|) to specify one flag from each group. Possible values are:
|How to handle exposed areas|
|FILL_CLR||[0x0000] fill exposed areas with the color in crFill.|
|FILL_RPT||[0x0001] stretch the edges of the image to fill exposed areas.|
|FILL_NOCHG||[0x0002] do not change or process exposed areas.|
|Type of information in the uWaveLen member|
|DIS_PER||[0x0000] The value in uWaveLen is a wavelength given as a percent of the bitmap dimensions. If this value is set, 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.|
User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
|DLG_RADIALWAVE_AUTOPROCESS||[0x00000001] process the image on OK. The pBitmap member of this structure should contain a valid bitmap.|
|DLG_RADIALWAVE_SHOW_CONTEXTHELP||[0x00000002] dialog should contain a context sensitive help icon.|
|DLG_RADIALWAVE_SHOW_PREVIEW||[0x00000004] show a preview of the image in the dialog. The pBitmap member of this structure should contain a valid bitmap.|
|DLG_RADIALWAVE_SHOW_TOOL_ZOOMLEVEL||[0x00000008] show the "Zoom to fit" and "Zoom Normal" toolbar buttons. The DLG_RADIALWAVE_SHOW_PREVIEW flag must be set in order to show these buttons.|
|DLG_RADIALWAVE_SHOW_APPLY||[0x00000080] Show the Apply button in the dialog. The dialog will not apply any effect unless the user presses the Apply button.|
