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.

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)".
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_SHOW_CONTEXTHELP [0x00000002] dialog should contain a context sensitive help icon.
pfnHelpCallback Ignored.
pHelpCallBackUserData Ignored.
