overlay(3NCURSES) overlay(3NCURSES)
NAME
overlay, overwrite, copywin - overlay and manipulate overlapped curses windows
SYNOPSIS
#include <curses.h>
int overlay(const WINDOW *srcwin, WINDOW *dstwin);
int overwrite(const WINDOW *srcwin, WINDOW *dstwin);
int copywin(const WINDOW *srcwin, WINDOW *dstwin, int sminrow,
int smincol, int dminrow, int dmincol, int dmaxrow,
int dmaxcol, int overlay);
DESCRIPTION
The overlay and overwrite routines overlay srcwin on top of dstwin. scrwin and dstwin are
not required to be the same size; only text where the two windows overlap is copied. The
difference is that overlay is non-destructive (blanks are not copied) whereas overwrite is
destructive.
The copywin routine provides a finer granularity of control over the overlay and overwrite
routines. Like in the prefresh routine, a rectangle is specified in the destination win-
dow, (dminrow, dmincol) and (dmaxrow, dmaxcol), and the upper-left-corner coordinates of
the source window, (sminrow, smincol). If the argument overlay is true, then copying is
non-destructive, as in overlay.
RETURN VALUE
Routines that return an integer return ERR upon failure, and OK (SVr4 only specifies "an
integer value other than ERR") upon successful completion.
X/Open defines no error conditions. In this implementation, copywin, overlay and over-
write return an error if either of the window pointers are null, or if some part of the
window would be placed off-screen.
NOTES
Note that overlay and overwrite may be macros.
PORTABILITY
The XSI Curses standard, Issue 4 describes these functions (adding the const qualifiers).
It further specifies their behavior in the presence of characters with multibyte rendi-
tions (not yet supported in this implementation).

NAME
composite - overlaps one image over another.
SYNOPSIS
composite [ options ... ] change-file base-file [ mask-file ] output-image
OVERVIEW
The composite program is a member of the ImageMagick(1) suite of tools. Use it to overlap
one image over another.

By default, the image format of `file' is determined by its magic number. To specify a
particular image format, precede the filename with an image format name and a colon (i.e.
ps:image) or specify the image type as the filename suffix (i.e. image.ps). Specify
'file' as '-' for standard input or output.
