Re: invoking ff from non-photoshop host

Hi Dave,

Here's my reverse-engineered version of the Filter Factory PARM
resource block.  Is this what you need?  It seems to be good for
most known (PC) versions of FF.  You can use the Win32 FindResource
API to locate the PARM resource.  E-mail me privately if you need
more details.

Cheers,

typedef struct {   //structure of FF PARM resource
     int cbSize;    //size of this structure
     int nVersion;  //0=original FF, 1=standalone filter
     int val[8];    //initial values of controls
     int popDialog; //true if need to pop a parameter dialog
     int unknown1;
     int unknown2;
     int unknown3;
     int map_used[4];   //true if map(n) is used
     int ctl_used[8];   //true if ctl(n) is used
     char category[252];    //Category name
     // Michael Johannhanwahr's protect flag...
     int iProtected;		// == 1 means protected
     char title[256];       //Filter title
     char copyright[256];   //Copyright info
     char author[256];      //Filter author(s)
