PICT Resource

(Mac OS) A PICT resource is a PICT file but takes a name and resource ID number. The PICT Resource format
supports RGB images with a single alpha channel, and Indexed Color, Grayscale, and Bitmap mode images without
alpha channels.
You can use the Import command or the Open command to open a PICT resource. When saving a file as a PICT
resource, you can specify the resource ID and resource name. As with other PICT files, you also specify bit depth and
compression options.

Pixar format

The Pixar format is designed specifically for high-end graphics applications, such as those used for rendering three­
dimensional images and animation. Pixar format supports RGB and grayscale images with a single alpha channel.
PNG format
Developed as a patent-free alternative to GIF, Portable Network Graphics (PNG) format is used for lossless
compression and for display of images on the web. Unlike GIF, PNG supports 24-bit images and produces
background transparency without jagged edges; however, some web browsers do not support PNG images. PNG
format supports RGB, Indexed Color, Grayscale, and Bitmap mode images without alpha channels. PNG preserves
transparency in grayscale and RGB images.

Portable Bit Map format

The Portable Bit Map (PBM) file format, also known as Portable Bitmap Library and Portable Binary Map, supports
monochrome bitmaps (1 bit per pixel). The format can be used for lossless data transfer because many applications
support this format. You can even edit or create such files within a simple text editor.
The Portable Bit Map format serves as the common language of a large family of bitmap conversion filters including
Portable FloatMap (PFM), Portable Graymap (PGM), Portable Pixmap (PPM), and Portable Anymap (PNM). While
the PBM file format stores monochrome bitmaps, PGM additionally stores grayscale bitmaps, and PPM can also
store color bitmaps. PNM is not a different file format in itself, but a PNM file can hold PBM, PGM, or PPN files.
PFM is a floating-point image format that can be used for 32-bits-per-channel HDR files.

QuickTime Movie format (ImageReady)

QuickTime Movie format is a cross-platform format used for time-based data, such as video and audio. In
ImageReady, you can save animations as QuickTime movies and open existing QuickTime movies as animations in
order to optimize them for the web.
Note: (Windows) QuickTime must be installed on your computer for the QuickTime Movie format to appear in the Files
Of Type menu. When working in Photoshop, you must jump to ImageReady before saving a document (such as an
animation) in QuickTime format.
Photoshop Raw format
The Photoshop Raw format is a flexible file format for transferring images between applications and computer
platforms. This format supports CMYK, RGB, and grayscale images with alpha channels, and multichannel and Lab
images without alpha channels. Documents saved in the Photoshop Raw format can be of any pixel or file size, but
they cannot contain layers.
