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.
