DESCRIPTIONThese programs read, display, and write image files in public formats. Jpg, gif, png, ppm, bmp, and yuv. read files in the corresponding formats and, by default, display them in the current window; options cause them instead to convert the images to Plan 9 image format and write them to standard output. Togif, Toppm, and topng read Plan 9 images files, convert them to GIF, PPM, or PNG, and write them to standard output.The default behavior of jpg, gif, and ppm is to display the file, or standard input if no file is named. Once a file is displayed, typing a character causes the program to display the next image. Typing a q, DEL, or control-D exits the program. For a more user-friendly interface, use which invokes these programs to convert the images to standard format, displays them, and offers scrolling, panning, and menu-driven navigation among the files. These programs share many options:
Jpg has two extra options used to process the output of the LML video card:
The togif and toppm programs go the other way: they convert from Plan 9 images to GIF and PPM, and have no display capability. Both accept an option -c to set the comment field of the resulting file. If there is only one input picture, togif converts the image to GIF format. If there are many files, though, it will assemble them into an animated GIF file. The options control this process:
Gif translates files that contain a `transparency' index by attaching an alpha channel to the converted image. Ico displays a Windows icon (.ico) file. If no file is specified, ico reads from standard input. Icon files contain sets of icons represeted by an image and a mask. Clicking the right button pops up a menu that lets you write any icon's image as a Plan 9 image (widthxheight.image), write any icon's mask as a Plan 9 image (widthxheight.mask), or exit. Selecting one of the write menu items yields a sight cursor. Move the sight over the icon and right click again to write. Toico takes a list of Plan 9 image files (or standard input) and creates a single icon file. The masks in the icon file will be the white space in the image. The icon file is written to standard output. SOURCE/src/cmd/jpgSEE ALSOBUGSWriting an animated GIF using togif is a clumsy undertaking. Visit the GSP FreeBSD Man Page Interface. |
