NAME

fdgt− get an image from a fast-disk picture file

SYNOPSIS

fdgt file ... [ options ]

DESCRIPTION

fdgt brings picture(s) from “tile-based” picture file(s) into a frame buffer.  The picture file must conform to Pixar’s standards for Fast-Disk tile-based picture files (see “The Format of Stored Pictures”, in the Advanced Topics section of the ChapLibraries User’s Guide).  The PIXPATH environment variable is used to find the picture(s).  Each picture header is read to determine the picture size, tile size, and component information. 

When using the fdgt and fdsv utilities, the CHAPLIBPATH environment variable must reference the library /usr/pixar/hsi/chap/lib/libfdpicio.a.

All Fast-Disk pathnames not beginning with a slash (/) are interpreted to be relative to the current Fast-Disk working directory specified by the FDCWD environment variable (see fdcwd(7)).

Options:

−fb fbname
frame buffer; see intro(1).

−o x y
causes the picture to be offset as it is read. x and y must be multiples of 32. 

−w xmin xmax ymin ymax
denotes a subwindow of the frame buffer into which the picture will be read; see intro(1). xmin and ymin must be multiples of 32, and xmax and ymax must be multiples of 32 plus 31 (i.e., xmax and ymax must be congruent to 31 mod 32). 

−t n specifies that only tile number n be read into the frame buffer. 

−l print the label stored with the picture. 

−v (verbose) elicits typeout of the frame buffer and recovered file name.
