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.

Member Description
uStructSize Size of this structure, in bytes. Use the sizeof operator to calculate this value.
pBitmap Ignored.
bZoomToFit Flag that indicates the initial zoom level for previewing the image. Possible values are:
  Value Meaning
  TRUE Set the initial zoom level to "Zoom to fit".
  FALSE Set the initial zoom level to "Normal (1:1)".
uAmplitude Magnitude of the wave. Valid values range from 0 to 100.
uWaveLen 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.
nPhase Wave phase shift, in hundredths of degrees. The valid range is from −36000 to 36000 (The value in degrees is nPhase divided by 100).
ptCenter 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.
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.
uRadialWaveFlags 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. The following are the flags that indicate how to handle exposed areas:
  Value Meaning
  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.
  The following are the flags that indicate the type of information in the uWaveLen member:
  Value Meaning
  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.
uDlgFlags User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
  Value Meaning
  DLG_RADIALWAVE_SHOW_CONTEXTHELP [0x00000002] dialog should contain a context sensitive help icon.
  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.
pfnHelpCallback Ignored.
pHelpCallBackUserData Ignored.
