The MULTIPLYDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImageEffect::DoModalMultiply function. After the user closes the dialog box, this structure is updated with information about the user's selections.
typedef struct _MULTIPLYDLGPARAMS{L_UINT uStructSize;pBITMAPHANDLE pBitmap;L_BOOL bZoomToFit;L_UINT uFactor;L_UINT32 uDlgFlags;LTCOMMDLGHELPCB pfnHelpCallback;L_VOID *pHelpCallBackUserData;} MULTIPLYDLGPARAMS, * LPMULTIPLYDLGPARAMS;
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.
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)". |
The multiplication factor by which to multiply the bitmap. The factor used is equal to uFactor / 100. Possible values are:
| If you are working with: | possible values are: |
|---|---|
| 16-bit grayscale images. | 0 - 6553500 |
| 12-bit images. | 0 - 409500 |
| images of other bits per pixel | 0 - 25500 |
User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
| Value | Meaning |
|---|---|
| DLG_MULTIPLY_AUTOPROCESS | [0x00000001] process the image on OK. The pBitmap member of this structure should contain a valid bitmap. |
| DLG_MULTIPLY_SHOW_CONTEXTHELP | [0x00000002] dialog should contain a context sensitive help icon. |
| DLG_MULTIPLY_SHOW_PREVIEW | [0x00000004] show a preview of the image in the dialog. The pBitmap member of this structure should contain a valid bitmap. |
| DLG_MULTIPLY_SHOW_TOOL_ZOOMLEVEL | [0x00000008] show the "Zoom to fit" and "Zoom Normal" toolbar buttons. The DLG_MULTIPLY_SHOW_PREVIEW flag must be set in order to show these buttons. |
