QuickTime Player does not cache the decompressed images or movie frames for PhotoJazz or any format. Instead, QuickTime Player relies on the PhotoJazz QT to decompress the images and movie frames again whenever any part needs to be redisplayed. This lets QuickTime Player operate on PhotoJazz images and movie frames of any size with very little memory. PhotoJazz QT is smart enough to decompress only those tiles which are visible. This selective decompression feature is especially useful when zooming in on huge images.

To view a still image without the big brushed-metal QuickTime Controller, select Movie > Get Info to open the Info window, select Movie in the Track pop-up menu, select Controller in the Category pop-up menu, and select None Movie Controller in the Movie Controller list.

Because PhotoJazz QT has built-in support for basic spatial transformations, you see a progressive display of the visible tiles of a PhotoJazz image for all the basic transformations QuickTime Player supports, including scaling, quarter-cycle rotation, reflection, and translation.

Scaling

Scaling: QuickTime Player offers three ways to scale a movie or video track: a set of menu items for common window scale factors, a new grow icon for arbitrary window resizing, and object handles for arbitrary video track resizing.

To resize a movie while maintaining the original aspect ratio:

1. Select Movie > Half Size to display the movie at half the original width and height.

or

1. Select Movie > Normal Size to display the movie at the original width and height.

or

1. Select Movie > Double Size to display the movie at double the original width and height.

or

1. Select Movie > Fill Screen to grow the movie to fill the screen, preserving its aspect ratio.

or

1. Press on the ridged triangle in the lower right corner and drag to the desired size.

Note that QuickTime Player's nonstandard grow icon can reduce the image to smaller than the window. Note also that QuickTime Player's windows have no zoom box in the title bar.

To resize a movie independently in width and height, without maintaining the aspect ratio:

1. Press on the ridged triangle and Shift-drag to the desired size.

To resize a video track while maintaining the same aspect ratio:

1. Select Movie > Get Info to open the Info window.
2. Select the appropriate Video Track in the Track pop-up menu.
3. Select Size in the Category pop-up menu.
4. Click Adjust to activate handles on the track image.
5. Press on one of the corner handles and Option-drag to the desired size (half or double).
6. Click Done to deactivate the track handles.

To resize a video track in only one dimension (width or height):

1. Select Movie > Get Info to open the Info window.
2. Select the appropriate Video Track in the Track pop-up menu.
3. Select Size in the Category pop-up menu.
4. Click Adjust to activate handles on the track image.
5. Press on one of the corner handles and Shift-drag to the desired size.
6. Click Done to deactivate the track handles.

To resize a video track independently in width and height, without maintaining the aspect ratio:

1. Select Movie > Get Info to open the Info window.
2. Select the appropriate Video Track in the Track pop-up menu.
3. Select Size in the Category pop-up menu.
4. Click Adjust to activate handles on the track image.
5. Press on one of the corner handles and drag to the desired size.
6. Click Done to deactivate the track handles.

Rotation

QuickTime Player offers two ways to rotate a video track: buttons for quarter-cycle rotation, and a rotation handle for arbitrary rotation.

To rotate a video track in quarter-cycle steps:

1. Select Movie > Get Info to open the Info window.
2. Select the appropriate Video Track in the Track pop-up menu.
3. Select Size in the Category pop-up menu.
4. Click to rotate the image one quarter turn clockwise.

or

1. Select Movie > Get Info to open the Info window.
2. Select the appropriate Video Track in the Track pop-up menu.
3. Select Size in the Category pop-up menu.
4. Click to rotate the image one quarter turn counterclockwise.

To rotate a video track by an arbitrary angle:

1. Select Movie > Get Info to open the Info window.
2. Select the appropriate Video Track in the Track pop-up menu.
3. Select Size in the Category pop-up menu.
4. Click Adjust to activate handles on the track image.
5. Press on the circle handle in the center and drag around to the desired angle.
6. Click Done to deactivate the track handles.

PhotoJazz QT does not support arbitrary rotation, so rotation by cumulative angles other than quarter-turns is handled by QuickTime, and progressive tile display is turned off.

Reflection

To reflect a video track about the vertical or horizontal axis:

1. Select Movie > Get Info to open the Info window.
2. Select the appropriate Video Track in the Track pop-up menu.
3. Select Size in the Category pop-up menu.
4. Click to display the image backwards.

or

1. Select Movie > Get Info to open the Info window.
2. Select the appropriate Video Track in the Track pop-up menu.
3. Select Size in the Category pop-up menu.
4. Click to display the image upside-down.

Translation

Although QuickTime Player's windows don't have scroll bars, if the window is too large to fit on your display you can still grab any edge of the window and move it around, even up under the menu bar. However, QuickTime Player does offer a way to move video tracks.

To move a video track in just one dimension (horizontal or vertical):

1. Select Movie > Get Info to open the Info window.
2. Select the appropriate Video Track in the Track pop-up menu.
3. Select Size in the Category pop-up menu.
4. Click Adjust to activate handles on the track image.
5. Press on the track image away from all handles and Shift-drag the track to the desired position.
6. Click Done to deactivate the track handles.

To move a video track arbitrarily:

1. Select Movie > Get Info to open the Info window.
2. Select the appropriate Video Track in the Track pop-up menu.
3. Select Size in the Category pop-up menu.
4. Click Adjust to activate handles on the track image.
5. Press on the track image away from all handles and drag the track to the desired position.
6. Click Done to deactivate the track handles.

For viewing convenience, PhotoJazz QT converts the pixels in the PhotoJazz source image to the pixel format of your display on the fly, so you don't have to wait for the whole windowful or the whole image to get decompressed before you see anything. See the Color Conversion feature for a table of pixel-format conversions built into PhotoJazz QT.

PhotoJazz QT also does its own masking, and only converts the visible pixels of the visible tiles, for even quicker results.

1. Select Movie > Get Info to open the Info window.
2. Select the appropriate Video Track in the Track pop-up menu.
3. Select Size in the Category pop-up menu.

PhotoJazz QT does not support shearing or arbitrary rotation, so these transformations are handled by QuickTime.
