IPASTE(1G)							    IPASTE(1G)

NAME    [Toc]    [Back]

     ipaste - display an image

SYNOPSIS    [Toc]    [Back]

     ipaste [-f] [-n] [-sx] [-o	xorg yorg] imgfile

DESCRIPTION    [Toc]    [Back]

     ipaste is a utility that displays images stored using the image library
     "libimage.a".  ipaste reads pixel values, image dimensions	and other
     relevant data from	the file imgfile via calls to the image	library.
     ipaste then displays the image in a window.  On machines with few bit
     planes, ipaste dithers the	image.

     The -f option causes ipaste to run	in the foreground.  Normally, ipaste
     forks off a background process to display the image while the foreground
     process exits back	to the command line.  With this	option the image is
     displayed by the foreground process.

     The -n option pastes the image without any	window manager border.	When
     the image is viewed in this way, access to	the window frame and its
     buttons is	disabled as the	frame itself is	not visible.  However the X
     window menu can still be popped up	under 4Dwm by pressing the left	CtrlShift
 keys	simultaneously and then	RIGHTMOUSE when	the cursor is on top
     of	the image.  The	Minimize/Stow and Quit menu items give the same
     results as	the control buttons on the visible window frame.  Moving the
     image around can still be accomplished via	the Move menu item, or by
     pressing down the left Ctrl-Shift keys simultaneously, then pressing
     MIDDLEMOUSE, and then moving the mouse.

     The -sx option pastes the image with a white border or frame surrounding
     it	in the style of	a Polaroid SX (TM) photograph.	This option, like -n,
     disables the window manager border.

     The -o xorg yorg option automatically pastes the image at a position on
     the screen	(absolute screen coordinates) that has as its origin (xorg,

     Pressing the Esc key on the keyboard will automatically quit out of
     ipaste now.  This is a nice short-cut when	the image you are viewing is
     borderless	(i.e. has been pasted up using the -n option).	However, due
     the way the Xserver works with auto-repeat	keys on	the keyboard (like
     Esc), if you hold down the	Escape key too long, and your current ipaste
     window has	another	ipaste window underneath it, you will now find the
     second ipaste window will also exit.  Be careful when you use the "Esc"
     key shortcut.

     In	the world of X,	the easiest way	to get access to the 4Dwm window
     manager menu while	over an	ipaste window (or any GL client)--so you can
     quit out of ipaste	in this	fashion--is to press either "Alt" key and then
     press RIGHTMOUSE.	This is	the easiest way	to stow, or iconize the	image
     and the safest way	to quite out of	a ipaste'd borderless window.

     UPARROWKEY) can now be used to scoot the ipaste window to the left, down,
     right, or up as long as the cursor	is on top of the ipaste	window when
     you press one of these keys.

     Caution:  ipaste will NOT work with image files made using	the old	gl
     program dither.  For these	dithered types of images (8 bits deep) you
     will need to first	use fromdi to convert them from	dithered into RGB
     format, and then can use ipaste to	display	them.  fromdi.c	lives in
     /usr/people/4Dgifts/iristools/imgtools, and the executable	is in the
     moregltools subsystem on the EOE2 software	product.

NOTES    [Toc]    [Back]

     On	machines having	less than 24 bits available for	RGB display, the
     displayed image may appeared to have lost some quality. This occurs when
     the image that was	saved was in colormap mode. The	pixel color index is
     expanded into the full RGB	information. When redisplayed, the RGB
     information is dithered on	these machines to approximate the original

     Under 4Dwm	there is a constraint on the minimum width a window can	have.
     This affects users	of ipaste(1G) who try to view image files which	have
     an	xsize of less than 75 pixels.  Quoting from the	"OSF/Motif
     Programmer's Guide", Version 1.1, Section, The Title Bar:

     The title bar, which may include a	title area, window menu	button,	and
     minimize and maximize buttons, is constrained so that all components in
     the title bar are always visible.	This necessitates a minimum frame size
     and, by extension,	a minimum size for your	application's window.  The
     size of the components in the title bar depends upon the size of the font
     you choose	for the	title area text.

     As	a user shrinks your client window horizontally,	space is removed from
     the title area first.  As the window is resized smaller, title text is
     clipped from the right.  The absolute minimum size	of the title bar is
     equal to the size of the buttons in the title bar,	plus a title area
     equivalent	to the width of	one title bar button.

     The standard minimum-width	window size in 4Dwm is 100 pixels.  This is
     based on the fact that SGI's buttons (which live in the area of the title
     bar) are 25 pixels	wide.  The min size is calculated to be	"buttonSize *
     4"	(assuming the buttons are of uniform size). Since ipaste has no
     "maximize"	button,	the min	size is	"buttonSize * 3".
