Rendering Actions

Using the Picturepark Rendering Chain you can generate a temporary still format for documents or videos and then modify the rasterized still images and use rendering actions, which may not be allowed on videos directly (e.g. Watermark).

Find details on the creation of output formats in the API documentation: https://demo.picturepark.com/Docs/Rest/index.html#operation/OutputFormat_Create

Alpha Handling Action

The alpha handling modification handles alpha channels (transparency) in images, so transparency in PNG is handled when converted into JPG (which has no transparency).

Color Conversion Action

The color conversion action is automatically applied in Picturepark when needed. This converts images from CMYK print usage to RGB web usage.

Crop Action

The crop modification crops your rectangle dimensions, starting at the x:y coordinates.

Resize Action

The resize modification resizes formats to a certain size. This is available for all file types (images, video, audio, document).

Rotate Action

You cannot select this rotate action or define properties, as it is automatically applied with predefined settings in Picturepark. Images are auto-rotated based on their Exif values.

Unsharp Mask Action

The unsharp mask action allows unsharp masking based on the specified amount, radius, and threshold. The following values need to be defined: Amount of 1 to 500 percent, Radius of 0.1 to 1000.0

Watermark Action

The watermark modification applies an image overlay. You need to store your watermark image (png, gif, tiff) on an absolute path on the server. Then you can define a distance from the four borders in pixels (margin left, margin top, margin right, margin bottom). You can leave the margins empty. You must set the opacity (0.1 to 1) used for transparency and an aspect ratio - the ratio of the width of a shape to its height (e.g., 8:5, 16:10, and 1.6:1 are the same aspect ratio).
