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.
| Member | Description | |
| uStructSize | Size of this structure, in bytes. Use the sizeof operator to calculate this value. | |
| pBitmap | Ignored. | |
| uTransition | The transition to use. Possible values are | |
| Value | Meaning | |

| EFX_TRANS_UPWARD_DIAG | Upward diagonal lines | |
| EFX_TRANS_CROSS | Cross lines | |
| EFX_TRANS_DIAG_CROSS | Diagonal cross lines | |
| crBack | 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. | |
| crFore | 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. | |
| uSteps | Number of steps in the gradient. | |
| uEffect | The effect to use. For a list of possible values, refer to Effect Types. | |
| uGrain | The grain size, in pixels. | |
| uDelay | The delay, in milliseconds | |
| uMaxPass | The maximum number of passes. | |
| bTransparent | 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. | |
| crTransparent | 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. | |
| uWandWidth | The wand width, in pixels. | |
| crWand | 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. | |
| uDlgFlags | User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are: | |
