Author: Jason_Williams (Xara Group Ltd) <camelotdev@xara.com> Date: 30/8/96 Parameters: -  [INPUTS] Returns: - The JCWPalette filter loads my own personal file format, which I invented to store PANTONE libraries in a reasonably sensible form. See also: PaletteFilter Definition at line 2328 of file coplfilr.cpp. { // Set up filter descriptions. FilterName.Load(_R(IDT_FILTERNAME_JCWPALETTE)); FilterInfo.Load(_R(IDT_FILTERINFO_JCWPALETTE)); FilterID = FILTERID_JCWPALETTE; #ifndef STANDALONE Flags.CanImport = TRUE; #else Flags.CanImport = FALSE; #endif // Never export, 'cos JCW is the only dude who knows the format! ;-) Flags.CanExport = FALSE; // And never show this filter in the UI Flags.ShowFilter = FALSE; m_ColoursAreSpots = FALSE; m_NumToImport = 0; }

INT32 JCWColourFilter::HowCompatible (  PathName &  Filename, ADDR  HeaderStart, UINT32  HeaderSize, UINT32  FileSize )  [virtual]

Examines a file to see how compatable it is with this filter. Author: Jason_Williams (Xara Group Ltd) <camelotdev@xara.com> Date: 30/8/96 Parameters: Filename  - the file being loads (allows checks on extensions). [INPUTS] HeaderStart - address of some bytes from the start of the file HeaderSize - the number of bytes at HeaderStart FileSize - the total length of the file Returns: Between 10 (Mine!) and 0 (Not Mine!) inclusive See also: Filter::HowCompatible Reimplemented from Filter.

BOOL JCWColourFilter::PostImport (  void   )  [virtual]

Called to allow post import cleanup (if required) for this filter. Author: Jason_Williams (Xara Group Ltd) <camelotdev@xara.com> Date: 30/8/96 Parameters: -  [INPUTS] -  [OUTPUTS] Returns: TRUE/FALSE for success/error Implements PaletteFilter. Definition at line 2517 of file coplfilr.cpp. { // Nothing to do, no cleanup required. return TRUE; }
