typedef struct _SPHERIZEDLGPARAMS
} SPHERIZEDLGPARAMS, * LPSPHERIZEDLGPARAMS;
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.
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)".|
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.
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.
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 outside the sphere and inside the sphere. You can use a bitwise OR (|) to specify one flag from each group. This flag is ignored if the nValue is negative. Possible values are:
|How to handle exposed areas outside the sphere|
|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.|
|How to handle exposed areas inside the sphere|
|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.|
User interface flags for this dialog, which determines the layout and action of the dialog. Possible values are:
|DLG_SPHERIZE_AUTOPROCESS||[0x00000001] process the image on OK. The pBitmap member of this structure should contain a valid bitmap.|
|DLG_SPHERIZE_SHOW_CONTEXTHELP||[0x00000002] dialog should contain a context sensitive help icon.|
|DLG_SPHERIZE_SHOW_PREVIEW||[0x00000004] show a preview of the image in the dialog. The pBitmap member of this structure should contain a valid bitmap.|
|DLG_SPHERIZE_SHOW_TOOL_ZOOMLEVEL||[0x00000008] show the "Zoom to fit" and "Zoom Normal" toolbar buttons. The DLG_SPHERIZE_SHOW_PREVIEW flag must be set in order to show these buttons.|
|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.|
