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.

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. |
