The TRANSITIONDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogEffect::DoModalGetTransition function. After the user closes the dialog box, this structure is updated with information about the user's selections.
typedef struct _TRANSITIONDLGPARAMS{L_UINT uStructSize;pBITMAPHANDLE pBitmap;L_UINT uTransition;COLORREF crBack;COLORREF crFore;L_UINT uSteps;L_UINT uEffect;L_UINT uGrain;L_UINT uDelay;L_UINT uMaxPass;L_BOOL bTransparent;COLORREF crTransparent;L_UINT uWandWidth;COLORREF crWand;L_UINT32 uDlgFlags;LTCOMMDLGHELPCB pfnHelpCallback;L_VOID *pHelpCallBackUserData;} TRANSITIONDLGPARAMS, * LPTRANSITIONDLGPARAMS;
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.
The transition to use. Possible values are
| Value | Meaning |
|---|---|
| EFX_TRANS_SOLID | Solid filling |
| EFX_TRANS_HORZ_LINE | Horizontal lines |
| EFX_TRANS_VERT_LINE | Vertical lines |
| EFX_TRANS_DOWNWARD_DIAG | Downward diagonal lines |
| EFX_TRANS_UPWARD_DIAG | Upward diagonal lines |
| EFX_TRANS_CROSS | Cross lines |
| EFX_TRANS_DIAG_CROSS | Diagonal cross lines |
The background color or the starting gradient color, if a gradient transition is used. 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.
The foreground color or the ending gradient color, if a gradient transition is used. 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.
Number of steps in the gradient.
The effect to use. For a list of possible values, refer to Effect Types.
The grain size, in pixels.
The delay, in milliseconds
The maximum number of passes.
Flag that indicates whether to use a transparent color. Possible values are:
| Value | Meaning |
|---|---|
| TRUE | Use the transparent color specified in crTransparent. |
| FALSE | Do not use a transparent color. |
The transparent color. 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.
The wand width, in pixels.
The wand color. 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.
