Print Plug-In provides a basic printing capability for The GIMP.
The current release supports PostScript, PCL (HP LaserJet and DeskJet), and ESC/P2 (EPSON Stylus Color) printers. The PostScript printer drivers handle PPD (PostScript Printer Description) files if you have them.
Using the Print Plug-In:
The Printer option provides selections for many common printers. Currently the print plug-in supports the following printers:
- PostScript printers
- HP DeskJet 500, 500C, 520, 540C, 600C, 660C, 68xC, 69xC, 850C, 855C, 855Cse, 855Cxi, 870Cse, 870Cxi, 1100C, 1120C, 1200C, and 1600C printers
- HP LaserJet II, III, IIIp, IIIsi, 4, 4L, 4P, 4V, 4Si, 5, 5FS, 5L, 5P, 5SE, 5Si, 6L, 6P printers
- EPSON Stylus Color, Color Pro, Color Pro XL, Color 400, Color 500, Color 600, Color 800, Color 1500, Color 1520, and Color 3000.
The Output Type option controls whether the printed output is in color or B&W (grayscale). This option is silently forced to B&W for grayscale images and B&W-only printers.
The Media Size option controls the size of the output. By default images are printed to fit the page and are automatically rotated to fill the largest area possible.
The Media Type option tells the printer what type of media is being used (Plain, Coated, etc). Not all printers support the media type option.
The Media Source option tells the printer which paper tray to print from. Not all printers support the media source option.
The Resolution option controls the resolution of the output. Not all printers support the resolution option.
The Orientation option controls whether the output is automatically rotated for maximum page coverage (Auto) or set to a specific orientation (Portrait or Landscape).
The Scaling option controls how large the printed image is. The default is to scale to a percentage of the printable area of the page. You can also specify an image resolution in pixels-per-inch (PPI) by clicking on the PPI radio button. The image is centered by default, however you can adjust the position of the image on the page by dragging the preview image.
The Brightness option controls the overall printed image brightness. A brightness of 100 is usually good for most B&W and PostScript printers, while most inkjet printers need a brightness between 100 and 120 for acceptable results.
Printing to a File
If you want to print to a file, select File from the Printer list. A file chooser dialog is displayed when you press the Print button. Warning, when you print to a file any existing file will be silently overwritten by this release of the plug-in!
Layered Images
Like most plug-ins, the print plug-in only reads the image from the active layer. If you want to print a composite of all visible layers you need to merge the layers (CTRL-M) and then print.
Supported Printers/Features
Most of the printer drivers in the print plug-in use the highest supported resolution for a printer, with the following exceptions:
- EPSON Stylus Color 600, 800, 1520, and 3000 - Currently the driver only supports 720 DPI printing in "compatibility" mode. This makes the drivers extremely slow compared to the Windows and Mac drivers. Unfortunately, I cannot provide optimized drivers (nor drivers for 1440x720) because of our NDA with EPSON.
- EPSON Stylus Photo, Photo Ex, Photo 700 - Currently the driver only supports 720 DPI printing in "compatibility" mode. This makes the drivers extremely slow compared to the Windows and Mac drivers, and you dont get the use of the light cyan and magenta inks (again, because of NDA restrictions.)

PNG plug-in provides Portable Network Graphics (PNG) file load & save modules for The GIMP. The plug-in supports all color modes and supports saving of interlaced images and setting the level of compression.

Using the PNG Plug-In:
Figure 1 shows the PNG save options window.
The Interlace toggle button selects interlaced output.
The Compression Level slider controls how much compression is applied to the image (0 = none, 9 = maximum).

Sharpen plug-in provides a sharpening filter to enhance the edges in a blurry image.

Using the Sharpen Plug-In
Figure 1 shows the sharpen plug-in window. The scrollbars allow you to pan within the image (in this case to the back of the duck in the foreground). The preview window shows the filter output using the current settings.

The Sharpness control selects the amount of sharpening to apply, from 1 to 99 percent. Higher values make the edges in the image increasing distinct.

UnPlug is a its a video download tool for Firefox.

UnPlug is an extension which lets you save video and audio which is embedded on a webpage.

UnPlug scans web pages and tells you where media players are getting their data from, and displays it as a simple hyperlink: in most cases, you can then follow the simple download link to save the media file.

UnPlug works for lots of sites including youtube.com, iflim.com, current.tv, myspace.com (video), revver.com, mobuzz.tv and lots more.

Unlike many other extensions, UnPlug scans the page, and if it doesnt know there the data comes from it can guess - correctly most of the time.

UnPlug your Plug-Ins and view media however you want!

GStreamer Base Plug-ins is a well-groomed and well-maintained collection of GStreamer plug-ins and elements, spanning the range of possible types of elements one would want to write for GStreamer.

GStreamer Base Plug-ins also contains helper libraries and base classes useful for writing elements. A wide range of video and audio decoders, encoders, and filters are included.

GStreamer is a library that allows the construction of graphs of media-handling components, ranging from simple Vorbis and Ogg playback to complex audio (mixing) and video (non-linear editing) processing.
Applications can take advantage of advances in codec and filter technology transparently. Developers can add new codecs and filters by writing a simple plugin with a clean, generic interface.
The GStreamer team is proud to announce a new release in the 0.10.x stable series of the GStreamer Base Plug-ins.
The 0.10.x series is a stable series targeted at end users. It is not API or ABI compatible with the stable 0.8.x series. It is, however, parallel installable with the 0.8.x series.
This module contains a set of reference plugins, base classes for other plugins, and helper libraries. This module is kept up-to-date together with the core developments. Element writers should look at the elements in this module as a reference for their development. This module contains elements for, among others:
device plugins: x(v)imagesink, alsa, v4lsrc, cdparanoia
- containers: ogg
- codecs: vorbis, theora
- text: textoverlay, subparse
- sources: audiotestsrc, videotestsrc, gnomevfssrc
- network: tcp
- typefind
- audio processing: audioconvert, adder, audiorate, audioscale, volume
- visualisation: libvisual

Enhancements:
- The Solaris-x86 plugin was ported to openQRM 3.1.4 and the Solaris-x86 assignment function was fixed.

SGI plug-in provides SGI image file load & save modules for The GIMP. The plug-in supports GRAY, GRAYA, RGB, and RGBA color modes.

Using the SGI Plug-In:
The Parameter Settings buttons control how much compression is applied to the image:
No Compression stores the image raw or verbatim.

RLE Compression stores the image as a sequence of repeated or non-repeated pixels.
Advanced RLE checks for duplicate lines and channels in the image and sometimes produces dramatically smaller images but also takes longer to save.
