NAME [Toc]

 imged - small image editor

SYNOPSIS [Toc]

 imged imgfile [ xsize ysize [ -rgb	]]

DESCRIPTION [Toc]

 imged is a	pixel-based editor for making changes to image files stored in
 the SGI imglib format. Images may be stored in colormap, RGB, or
 greyscale format.
 imged may also be used to create a	new colormap or	RGB image by
 specifying	an X and Y size	on the command line. If the -rgb flag is
 given, the	new image is created as	RGB, otherwise it is created as	a
 colormap image. New images are initialized with a	solid grey background.
 The imged window contains a scaled	representation of the image being
 edited. The scale of the image can	be changed by resizing the window. The
 pixels in the image will appear as	squares, optionally separated by black
 lines. The title of the imged window indicates the type of image that is
 being edited.
 The three mouse buttons all have a	function within	imged .	The left and
 middle buttons both act as	brushes. Each brush remembers a	"current
 color". While the brush buttons are pressed, drawing will take place in
 the color of that brush. If the Shift key is held down, pushing a brush
 button causes the brush to	change color to	the color of the pixel
 directly under the	cursor.	The Alt	key also modifies the operation	of the
 brush buttons for RGB images. While the Alt key is held down, drawing
 will be performed in "blending mode". The pixels being drawn on will be
 blended with the color of the brush.
 Pushing the right button causes a popup menu to appear, which can be used
 to	change the mode	of imged. Several options are available. The "no
 grid" option turns	off the	grid of	black lines separating the pixels.
 Similarly,	the "grid" option turns	the grid on.
DRAWING	MODES
 imged has four different drawing modes: sketch, rect, line, and smear.
 To	change the drawing mode, select	the appropriate	entry from the popup
 menu with the right mouse button.
 sketch mode lets	you change pixels directly under the cursor to the
		 brush color when a brush button is depressed. Holding a
		 brush button	down while moving the mouse results in a
		 sketch-like drawing.
 rect mode	 lets	you create rectangles by pressing a brush button at
		 one corner of the desired rectangle and holding the button
		 while moving	the cursor. When you release the button, the
		 rectangle is	drawn.

 line mode	 lets	you draw straight lines	by pressing a brush button at
		 one end of the desired line segment and holding the button
		 while moving	the cursor. When you release the button, the
		 line	segment	connecting the two points is drawn.
 smear mode	 is only available for use with RGB pictures.	 It lets you
		 smear an area with the brush. The pixels surrounding the
		 pixel the brush is on are used to determine the color used
		 for that pixel.

HALFTONE [Toc]

 Often when	editing	small images, you need the ability to draw
 checkerboard patterns of pixels. This can be done easily by selecting the
 "halftone"	option from the	popup menu. The	right and middle mouse buttons
 will draw on pixels of opposite parity. To	turn off the halftone mode,
 select the	"solid"	option from the	menu.
WRITING	CHANGES
 To	write out changes to an	image, select the "write" option from the
 popup menu. The current state of the image	will be	written	to the file be
 edited. Changes must be written to	a file to be saved.

DIAGNOSTICS [Toc]

 Exit status is 1 if an error is encountered.
