Objectives

Conditionals allow us to direct the use of transformations based on the results of logical expressions.

• Syntax of Conditionals for building logical expressions
• Identify Intrinsic Properties of Images and Video
• Logical Expressions use IF, IF/END and IF/ELSE/END
• Use Intrinsic properties of Assets to make to make decisions about how to apply transforms
  • Width
  • Aspect Ratio
  • Tags
  • Context
  • Image Layers

In this module we'll look at how conditionals can help with these use cases:

• “Debugging”: text overlay informs you of the result of your logical expression
• Responsive Images and Video: you need a portrait aspect ratio so test intrinsic width and aspect ratio
• Watermark: Apply video and text overlays to video base by testing a value in a tag
• Overlay Image based on context (metadata): value to apply overlay based on context value for asset license
• Overlay text and image based on PSD layer count
