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. | |
