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.

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.

uTransition

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

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:

Value Meaning
DLG_TRANSITION_SHOW_CONTEXTHELP [0x00000001] dialog should contain a context sensitive help icon.
DLG_TRANSITION_SHOW_PREVIEW [0x00000002] show a preview of the image in the dialog. The pBitmap member of this structure should contain a valid bitmap.
DLG_TRANSITION_AUTOPREVIEW [0x00000004] auto preview when options change
DLG_TRANSITION_FORECOLOR [0x00000008] fore color is an option
DLG_TRANSITION_BACKCOLOR [0x00000010] back color is an option
DLG_TRANSITION_DELAY [0x00000020] transition delay is an option
DLG_TRANSITION_GRAIN [0x00000040] transition grain is an option
DLG_TRANSITION_EFFECT [0x00000080] paint effect is an option
DLG_TRANSITION_PASSES [0x00000100] transition passes is an option
DLG_TRANSITION_WAND [0x00000200] wand is an option
DLG_TRANSITION_TRANSPARENT [0x00000400] transparency is an option
DLG_TRANSITION_GRADIENT [0x00000800] gradient is an option

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
