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.
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)". |
uFactor | 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 |
uDlgFlags | User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are: | |
Value | Meaning | |
DLG_MULTIPLY_SHOW_CONTEXTHELP | [0x00000002] dialog should contain a context sensitive help icon. | |
pfnHelpCallback | Ignored. | |
