.TH FLICKFILE 9.5 .CT 1 comm_term .SH NAME movies \- graphics movie file formats .SH DESCRIPTION Movie files are generated by .I preflicks and used by .IR fflicks ; see .IR flicks (9.1). The format of a movie files is: .IP .EX struct Header { unsigned char version; short header_length; short nr_frames; unsigned char nr_tables; struct LOOKUP_TABLE { short number_of_entries; struct { short count; unsigned char value; } table[256]; } Table[nr_tables]; }; struct Frame { short width, height; short compacted_length; unsigned char which_table; unsigned char data[compacted_length]; } Frame[nr_frames]; .EE Each .B short in the above structure is present as a two-byte number in the file, most significant byte first. Each .B "unsigned char" is a single byte. .TP .B version software version number, to ensure compatibility between producer and consumer of the file. .PD0 .TP .B header_length total length in bytes of the lookup table(s) used to encode the file plus three bytes (the next three that follow). .TP .B nr_frames total number of movie frames in the file. .TP .B nr_tables number of lookup tables. .TP .B nr_entries number of entries in the lookup table (maximum 256). .TP .B count .B value pixel value and a count of how many times that value is to be repeated. .PD .PP Immediately following the lookup tables begin the frames encoded in an indirect run-length code. Each frame is described by .BR width , .BR height , and the .B compacted_length of the frame in bytes. The frame is coded in raster-scan order as a sequence of indexes into the table numbered .BR which_table (counting from 0). .SH FILES _movie .SH "SEE ALSO" .IR flicks (9.1), .IR pico (1), .IR rebecca (9.1)
