Compression

Compression reorganizes the way a picture or file is stored in computer memory and on disk so that the file uses less space.

The computer can work more efficiently with the compressed file, and display images faster on screen.


Uncompressed

The state of a picture when it is displayed (whether or not the picture has been previously compressed).

A picture's uncompressed size refers to the amount of memory it occupies.  It is not necessarily the same as the size of the original picture from which the picture was compressed.


Color

The level of color at which a picture is stored.  For example, millions of colors (24-bit), 256 colors (8-bit), or black and white (1-bit).

Every picture is stored at a specific color setting, determined when the picture was first created or compressed.


Compression ratio

The comparison of a pictures's compressed size on disk to its uncompressed size in memory.


JPEG

Joint Photographic Experts Group, an international standard-setting committee that developed a standard for image compression used by many computers and programs.

QuickTime for Windows' image display software supports the JPEG standard.


Quality

A setting that controls the degree of compression applied by a QuickTime compressor.

A higher quality setting causes less image compression to be applied.  This results in better image quality, but limits the saving in storage size.


About Picture Viewer

Picture Viewer allows you to view a picture file in a window.  You can zoom in and out, print the picture, copy the picture, and get information about the picture.  Picture Viewer automatically uncompresses the picture if it is compressed in the picture file.

Picture viewer can maintain excellent image quality and color while displaying an image that may have been compressed by 90% or more.

Glossary


Picture file

A DOS file containing a QuickTime for Windows picture.  These files are characterized by the DOS suffix .PIC.

For example: HOME.PIC might be the name of a file that contains a QuickTime picture of your house.

The picture in the .PIC file may be compressed in one of several different QuickTime compression formats, or the picture may be not compressed in the file.  The pictures are stored in the PICT format inside the picture files.


Printing a picture

To print an image, choose "Print" from the File menu.  The image prints at its actual size, if it fits on a single page.  If not, the image is reduced until it fits on the page.

To change the settings for page orientation, size, and printing options, choose "Print Setup" from the File menu.

Glossary


Image

The QuickTime picture displayed on the screen.


Getting information about a picture

To see information about a picture, choose "Get Image Info" from the Image menu.

"Get Image Info" provides information about the picture file, the size (in pixels) of the
image, the colors, the compression, the quality of the image, and the uncompressed size of the picture.

Glossary


Changing the display size of a picture
Changing the display size of the picture

You can change the display size of the image by changing its magnification percentage.  Changing the magnification doesn't affect the size of the original image, just the way you see it on the screen.

As you change the magnification, you see more or less of the picture, depending upon the capabilities of your video hardware and the resolution at which the picture is stored in the file .

To change the magnification, drag the slider in the bottom left section of the window. (You can also use the + and - keys on the numeric keypad to change the magnification.)

The slider

The slider lets you set magnification to 25%, 50%, 75%, 100%, 150%, 200%, or 400%:

•	100% magnification provides an optimum pixel-for-pixel display of the picture.

•	At less than 100%, the image has a lower resolution than the picture stored in the picture file.

•	At greater than 100%, one pixel from the picture takes multiple pixels on the screen.

Example: A picture is stored in the QuickTime for Windows file at 1024 x 768 pixels and 256 colors.  Your screen can only show 640 x 480 pixels at 256 colors.  When the image first appears the value will be 100% and you will only see a portion of the picture (the upper left part).  You can see the entire picture by setting the slider to a value less than 100% but you will see a loss of resolution in the image.

Using picture options
Setting QuickTime picture options

The picture options allow you to control how a picture looks when it is pasted into a document or embedded in an OLE destination document. You can reach the Options dialog box from either of two locations:

•	In Picture Viewer, select "Options" from the Edit menu.

•	In a destination document, select "QuickTime Picture Options" from the Edit menu.

You can set options to show the picture controls, put a frame around the picture, and use the picture pallette.

Use the Icon option to display the picture as an icon in the destination document.

•	To paste or embed the picture as an icon, check Icon.  When the icon is double-clicked, the image is displayed in a stand-alone window.  If Display Title Bar is checked, the image has a title bar and can be moved.  Otherwise, the image is displayed in the center of the destination document.

•	To paste or embed the picture at the selected size, leave Icon unchecked. When the picture is double-clicked, it is displayed in place.

Use the Save As default button to save a complete set of options as your defaults.

Use the Restore To Default button to restore your last set of defaults.

About Object Linking and Embedding (OLE)

OLE is a technology that allows you to place "objects" -- such as movies, pictures, or spreadsheets -- into other documents. For example, you can use OLE to embed a QuickTime picture into a word-processing document.

Readers of your document can double-click the picture to view it just as if they were using Picture Viewer. OLE also allows you to edit the embedded picture from the destination document.

Your Windows user's guide has more information on using OLE. See the chapter that covers integrating your Windows applications.

Glossary
