6.0 Setup Functions

6.1 Memory Layout

Memory Plane Configuration:

The memory plane configuration is defined by width, height, and depth. The size of the memory or image plane determines the maximum size of an image that can be loaded into memory. The depth of the memory plane determines how many bands of an image and/or how many images can be loaded into memory at one time.

Width:

The memory plane width defines the number of samples that can be loaded into memory. Images larger than this size will be subsampled to fit within the defined width. The default width is 1024.

Height:

The memory plane height defines the number of lines that can be loaded into memory. Images larger than this size will be subsampled to fit within the defined height. The default height is 1024.

Depth:

The memory plane depth defines the number of image bands that can be loaded into memory at one time. The default depth is three.

Viewport Configuration:

The viewport configuration is defined by width and height. This size determines what portion of the loaded image is visible. If the loaded image is larger than the viewport size, scrollbars allow the user to view the remainder of the image.

Width:

The viewport width defines the number of samples that are visible at one time. The default width is 512.

Height:

The viewport height defines the number of lines that are visible at one time. The default height is 512.

Allocate:

Allocate the amount of memory required based on the memory plane width, height, and depth specified. If a sufficient amount of memory is available, the layout panel is closed. If a sufficient amount of memory is not available, an error message is displayed and the layout panel is left open so that the user may modify the layout parameters and try again.

Reset:

Set both the memory plane configuration parameters and the viewport configuration parameters back to their default values.

Cancel:

Close the layout panel without modifying the current layout.
