MULTIPLYDLGPARAMS

typedef struct _MULTIPLYDLGPARAMS

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.

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.

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_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.

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
