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.

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. |

pfnHelpCallback |
Ignored. |
|
|
pHelpCallBackUserData |
Ignored. |
