Display Image Settings

Display image settings enable you to set whether you want to automatically generate display-quality versions of images when full resolution images are imported. You can also determine the display image format, quality and compression settings. Display images optimize the end-user display, and you can use the Archival File Manager to handle the storage of full resolution versions of those images (i.e., to set up and manage archive volume locations).

You can edit display image settings if you have rights to configure settings and field properties. New collections are enabled by default to automatically generate display-quality versions of images when full resolution images are imported.

For detailed information on using display images and the Archival File Manager, see the help topic Archival File Manager.

Display image settings defined in Collection Configuration apply to all import methods, except for the Web-based Add and Connexion digital import. Project Client users can override these settings when working with full resolution files by editing project settings. For more information, see About Project Settings.

Setting Definition Options
Generate display images from full-resolution images Enables you to set whether you want to automatically generate display-quality versions of images when full resolution images are imported. No. Full resolution images will not have a display version automatically derived.

Yes. Full resolution images will have a display version automatically derived to optimize end-user display.
Format/file type Specifies the file format to use for display-quality versions. JPEG2000 (default)
JPEG
JPEG2000: Lossy compression Compresses display images in JPEG2000 format by a specified compression ratio or by a quality selection. By compression ratio: Compresses by a default 10:1 ratio (default) or by ratio you specify, up to 100:1.

By quality selection:
Minimum
Medium (default)
High
Maximum
JPEG2000: Tile dimensions Enables you to set the tile dimensions for the display images. If the tile dimensions are smaller than the image dimensions, some tiles may extend beyond the borders of the image. 512 x 512
1024 x 1024 (default)
2048 x 2048
JPEG2000: Quality layers Specifies how to build layers so the image quality increases with each layer, and the image distortion shrinks from layer to layer. 10 – 30
(20 default)
JPEG: Maximum display image size Enables you to specify the largest dimensions for generated display images. 640 x 480
800 x 600 (default)
1024 x 768
Other
JPEG: Quality Compresses display images in JPEG format by a quality selection. To further refine compression, you can specify a number within the quality range. Low (10-29)
Medium (30-59)
High (60-99)
Maximum (100 - default)
