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 |
Zoom wave magnitude. The value must be greater than zero. |
|
uFrequency |
The number of repeated waves along the radial line.The value must be greater than zero. |
|
nPhase |
Wave phase shift. The valid range is from –36000 to 36000. |
|
uZoomFactor |
The percentage the wave grows as it moves from the image center. The valid range is from 0 to 100. |
|
ptCenter |
POINT structure that contains the center point from which the wave is zoomed. 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 of undefined area. 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. |
|
uZoomWaveFlags |
Flags that indicate how exposed areas will be handled. Possible values are: |
|
|
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_NOCHANGE |
[0x0002] do not change exposed areas. |
uDlgFlags |
User interface flags for this dialog, which determines the layout and action of the dialog. Possible values are: |
|
|
Value |
Meaning |
|
DLG_ZOOMWAVE_SHOW_CONTEXTHELP |
[0x00000002] dialog should contain a context sensitive help icon. |
|
DLG_ZOOMWAVE_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. |
