The REMAPINTENSITYDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogColor::DoModalRemapIntensity 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)".

uChannel

Value that represents the channel for which to change the intensity. Possible values are:

Value Meaning
CHANNEL_MASTER [0] All channels.
CHANNEL_RED [1] Red channel only.
CHANNEL_GREEN [2] Green channel only.
CHANNEL_BLUE [3] Blue channel only.

puRGBLookup

Pointer to a table of integers containing a lookup table for the RGB channel values. LEADTOOLS will allocate this during the call to LDialogColor::DoModalRemapIntensity unless you called the LDialogBase::EnableAutoProcess. You should free this pointer using the Windows API GlobalFree when it is no longer needed. The length of the table is in uLookupLen. You should use this structure member if the user sets uChannel to CHANNEL_MASTER.

puRedLookup

Pointer to a table of integers containing the Red channel values. LEADTOOLS will allocate this during the call to LDialogColor::DoModalRemapIntensity unless you called the LDialogBase::EnableAutoProcess. You should free this pointer using the Windows API GlobalFree when it is no longer needed. The length of the table is in uLookupLen. You should use this structure member if the user sets uChannel to CHANNEL_RED.

puGreenLookup

Pointer to a table of integers containing the Green channel values. LEADTOOLS will allocate this during the call to LDialogColor::DoModalRemapIntensity unless you called the LDialogBase::EnableAutoProcess. You should free this pointer using the Windows API GlobalFree when it is no longer needed. The length of the table is in uLookupLen. You should use this structure member if the user sets uChannel to CHANNEL_GREEN.

puBlueLookup

Pointer to a table of integers containing the Blue channel values. LEADTOOLS will allocate this during the call to LDialogColor::DoModalRemapIntensity unless you called the LDialogBase::EnableAutoProcess. You should free this pointer using the Windows API GlobalFree when it is no longer needed. The length of the table is in uLookupLen. You should use this structure member if the user sets uChannel to CHANNEL_BLUE.

uLookupLen

Length of the lookup table. Possible values are:

Value Meaning
65536 For 16-bit gray or 48-bit images.
4096 For 12-bit images.
256 For other-bits images.

uDlgFlags

User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:

Value Meaning
DLG_REMAPINTENSITY_AUTOPROCESS [0x00000001] process the image on OK. The pBitmap member of this structure should contain a valid bitmap.
DLG_REMAPINTENSITY_SHOW_CONTEXTHELP [0x00000002] dialog should contain a context sensitive help icon.
DLG_REMAPINTENSITY_SHOW_PREVIEW [0x00000004] show a preview of the image in the dialog. The pBitmap member of this structure should contain a valid bitmap.
DLG_REMAPINTENSITY_SHOW_TOOL_ZOOMLEVEL [0x00000008] show the "Zoom to fit" and "Zoom Normal" toolbar buttons. The DLG_REMAPINTENSITY_SHOW_PREVIEW flag must be set in order to show these buttons.

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
