The BENDINGDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImageEffect::DoModalBending 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. |
|
bZoomToFit |
Flag that indicates the initial zoom level for previewing the image. Possible values are: |
|
|
Value |
Meaning |
|
TRUE |
Set the initial zoom level to "Zoom to fit". |
|
FALSE |
Set the initial zoom level to "Normal (1:1)". |
nValue |
Amount of stretching, where positive values stretch the pixels toward edges, and negative values stretch the pixels toward the center. Possible values range from ©500 to 500. |
|
ptCenter |
A POINT structure that contains the center of the arc. This is ignored when either BND_HORZ or BND_VERT is set in the uBendingFlags member. 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. |
|
uBendingFlags |
Flags that indicate how to handle peripherally exposed areas, how to handle centrally exposed areas and the type of bending. You can use a bitwise OR (|) to specify one flag from each group. |
|
|
The following are the flags that indicate how to handle peripherally exposed areas: |
|
|
Value |
Meaning |
|
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. |
|
The following are the flags that indicate how to handle an exposed center: |
|
|
Value |
Meaning |
|
FILL_ROT |
[0x0000] Rotate the image inside the arc pattern. |
|
FILL_WOUTROT |
[0x0010] Fill the exposed center as you would any other exposed area. This is determined by setting the FILL_CLR, FILL_RPT or FILL_NOCHG flags. This flag is ignored if the nValue is negative. |
|
The following are the flags that indicate how the bitmap is bent: |
|
|
Value |
Meaning |
|
BND_NORM |
[0x0000] Stretch the image along the vertical and horizontal planes. |
|
BND_HORZ |
[0x0100] Stretch the image along the horizontal plane. |
|
BND_VERT |
[0x0200] Stretch the image along the vertical plane. |
uDlgFlags |
User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are: |
|
|
Value |
Meaning |
|
DLG_BENDING_SHOW_CONTEXTHELP |
[0x00000002] dialog should contain a context sensitive help icon. |
|
DLG_BENDING_SHOW_APPLY |
[0x00000080] Show the Apply button in the dialog. The dialog will not apply any effect unless the user presses the Apply button. |
pfnHelpCallback |
Ignored. |
|
pHelpCallBackUserData |
Ignored. |
