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

puMaskLookup

Lookup table that identifies which values in the Hue, Saturation, and Value Lookup tables are valid. For example, if puMaskLookup[i] is non-zero, then puHueLookup[i], puSaturationLookup[i], and puValueLookup[i] are valid for i pixel remapping. LEADTOOLS will allocate this during the call to LDialogColor::DoModalRemapHue 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.

puHueLookup

Hue lookup table. If the puMaskLookup table value for a particular pixel hue is non-zero, then the hue is changed to the corresponding entry in puHueLookup. LEADTOOLS will allocate this during the call to LDialogColor::DoModalRemapHue 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.

puSaturationLookup

Saturation lookup table. If the puMaskLookup table value for a particular pixel saturation is non-zero, then the saturation is changed to the corresponding entry in puSaturationLookup. LEADTOOLS will allocate this during the call to LDialogColor::DoModalRemapHue 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.

puValueLookup

Value lookup table. If the puMaskLookup table value for a particular pixel value is non-zero, then the value is changed to the corresponding entry in puValueLookup. LEADTOOLS will allocate this during the call to LDialogColor::DoModalRemapHue 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.

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 determines the layout and action of the dialog. Possible values are:

 

Value

Meaning

 

DLG_REMAPHUE_SHOW_CONTEXTHELP

[0x00000002] dialog should contain a context sensitive help icon.

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
