INVERTEDTEXTDLGPARAMS

typedef struct _INVERTEDTEXTDLGPARAMS 
{ 
   L_UINT uStructSize;

The INVERTEDTEXTDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogDocument::DoModalInvertedText 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

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)".

InvertedText

INVERTEDTEXT structure that LEADTOOLS uses to find and correct inverted text. You should set the pBitmapRegion member of the INVERTEDTEXT structure to a valid address and fill the uBitmapStructSize member with the proper value.

✎ NOTE

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

crWhiteArea

Color used to fill the inverted white 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.

crBlackArea

Color used to fill the inverted black 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_INVERTEDTEXT_SHOW_CONTEXTHELP [0x00000002] dialog should contain a context sensitive help icon.

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
