Adaptive Media Configuration Reference
Liferay 7.3 U28+/GA28+ and 7.4 U78+/GA78+
With Adaptive Media, you can configure supported media types, determine the resolutions used for previews and thumbnails in the document library, and more. To access these settings,
-
Open the Global Menu (
), go to the Control Panel tab, and click System Settings. -
Click Adaptive Media under Content and Data.
Configuration options appear in four tabs:
- System Images Resolutions: Configure resolutions used for document library thumbnails and previews.
- Images: Configure which media types are supported by Adaptive Media.
- ImageMagick: Configure which media types are generated using ImageMagick.
- Processes: Configure asynchronous processing.
Systems Images Resolutions
Override Adaptive Media’s default behavior for document library previews and thumbnails. By default, Adaptive Media chooses the best image resolution for previews and thumbnails based on the closest dimensions to the user’s screen type and resolution. But you can enter resolution IDs to override this process (e.g., Preview-1000x0).
| Field | Description |
|---|---|
| Preview Configuration | Enter a resolution ID to override the default adaptive media behavior for document library previews. |
| Thumbnail Configuration | Enter a resolution ID to override the default adaptive media behavior for document library thumbnails. |
| Custom Thumbnail Configuration 1 | Enter a resolution ID to override the default adaptive media behavior for document library custom thumbnail 1. |
| Custom Thumbnail Configuration 2 | Enter a resolution ID to override the default adaptive media behavior for document library custom thumbnail 2. |
Images
Determine the media types processed by Adaptive Media and enable or disable Gifsicle.
| Field | Description |
|---|---|
| Supported MIME Type | Determine the media types processed by Adaptive Media. If an image is uploaded and its media type is not listed, Adaptive Media ignores the image. By default, this list includes bmp, gif, jpeg, pjpeg, png, svg+xml, x-citrix-jpeg, x-citrix-png, x-ms-bmp, and x-png. |
| Field | Description |
|---|---|
| Gifsicle | You can enable Gifsicle to adapt gif files. See Enabling Optimization of Animated GIFs for more information. |
ImageMagick
Determine which media types are processed using ImageMagick. To use ImageMagick, you must first install it on your Liferay server. See Enabling ImageMagick and Ghostscript for more information.
| Field | Description |
|---|---|
| Supported MIME Type | Determine the media types processed by ImageMagick in Adaptive Media. If an image is uploaded and its media type isn’t in this list, Adaptive Media does not use ImageMagick for generating its preview. By default, this list contains avif, gif, heic, tiff, and webp, but you can add other media types. See ImageMagick documentation for a list of supported media types. |
Processes
Configure Adaptive Media’s asynchronous processing. Modify these values to improve performance.
| Field | Description |
|---|---|
| Max Processes | Set the maximum number of processes for generating adapted media. The default value is 5. |
| Core Processes | Set the number of processes always available for generating adapted media. The default value is 2. This value cannot exceed the maximum number of processes. |
Larger values for Max Processes and Core Processes can consume large amounts of memory and result in out of memory errors. Out of memory errors can also occur if source images are large. You should run performance tests to optimize these settings for the amount of memory available on your system.
