SPHERIZEDLGPARAMS

Summary

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.

Syntax

typedef struct _SPHERIZEDLGPARAMS 
{ 
   L_UINT uStructSize; 
   pBITMAPHANDLE pBitmap; 
   L_BOOL bZoomToFit; 
   L_INT nValue; 
   POINT ptCenter; 
   COLORREF crFill; 
   L_UINT uSpherizeFlags; 
   L_UINT32 uDlgFlags; 
   LTCOMMDLGHELPCB pfnHelpCallback; 
   L_VOID  *pHelpCallBackUserData; 
} SPHERIZEDLGPARAMS,  * LPSPHERIZEDLGPARAMS; 

Members

uStructSize

Size of this structure, in bytes. Use the sizeof operator to calculate this value.

pBitmap

Pointer to the bitmap handle that references the bitmap used for preview or processing.

bZoomToFit

Flag that indicates the initial zoom level for previewing the image. Possible values are:

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. This flag is ignored if the nValue is negative. Possible values are:

uDlgFlags

User interface flags for this dialog, which determines the layout and action of the dialog. Possible values are:

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
