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

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

Alpha Handling Action — The alpha handling modification takes care of the handling of alpha channels (transparency) in images, so how is transparency in png handled when converted into jpg (which has no transparency).

Crop Action — The crop modification crops your rectangle dimensions starting at the x:y coordinates.

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 Pixel and Threshold of 1 to 255 levels.

Watermark Action — The watermark modification applies and 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 pixel (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).

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

Color Conversion Action — The color conversion modification is automatically applied in Picturepark, which can convert images from CMYK print usage to RGB web usage.
