The SPHERIZEDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImageEffect::DoModalSpherize 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)". | |
| 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. | |
