The LINEREMOVEDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogDocument::DoModalLineRemove 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 1-bit 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)".

LineRemove

LINEREMOVE structure that LEADTOOLS uses to perform the line removal operation.You should pass valid pBitmapRegion address and fill the uBitmapStructSize with the proper value.

✅ IMPORTANT

It's the user's responsibility to free the region in pBitmapRegion, if there is one, using LBitmapRgn::Free.

crModification

Color used to fill the modified areas. This is used only for dialog previewing purposes. 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_LINEREMOVE_AUTOPROCESS [0x00000001] process the image on OK. The pBitmap member of this structure should contain a valid 1-bit bitmap.
DLG_LINEREMOVE_SHOW_CONTEXTHELP [0x00000002] dialog should contain a context sensitive help icon.
DLG_LINEREMOVE_SHOW_PREVIEW [0x00000004] show a preview of the image in the dialog. The pBitmap member of this structure should contain a valid 1-bit bitmap.
DLG_LINEREMOVE_SHOW_TOOL_ZOOMLEVEL [0x00000008] show the "Zoom to fit" and "Zoom Normal" toolbar buttons. The DLG_LINEREMOVE_SHOW_PREVIEW flag must be set in order to show these buttons.

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
