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)". |
nValue |
Amount of stretching where positive values stretch the central pixels toward the edges and negative values stretch the pixels toward the center. Valid range is from –500 to 500. |
|
ptCenter |
POINT structure that contains the center of the sphere. 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. |
|
uSpherizeFlags |
Flags that indicate how to handle exposed areas outside the sphere and inside the sphere. 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 outside the sphere: |
|
|
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 how to handle exposed areas inside the sphere: |
|
|
Value |
Meaning |
|
FILL_ROT |
[0x0000] Rotate the image inside the sphere pattern. |
|
FILL_WOUTROT |
[0x0010] Fill the exposed center of the sphere in the same manner as exposed areas outside the sphere. |
|
This flag is ignored if the nValue is negative. |
uDlgFlags |
User interface flags for this dialog, which determines the layout and action of the dialog. Possible values are: |
|
|
Value |
Meaning |
|
DLG_SPHERIZE_SHOW_CONTEXTHELP |
[0x00000002] dialog should contain a context sensitive help icon. |
|
DLG_SPHERIZE_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. |
