Blend Modes

In this example, we will show you how to use the CreativeEditor SDK’s CreativeEngine to modify a blocks appearance through the block API.

Common Properties

Common properties are properties that occur on multiple block types. For instance, fill color properties are available for all the shape blocks and the text block. That’s why we built convenient setter and getter functions for these properties. So you don’t have to use the generic setters and getters and don’t have to provide a specific property path. There are also has* functions to query if a block supports a set of common properties.

Opacity

Set the translucency of the entire block.

supportsOpacity(id: DesignBlockId): boolean

Query if the given block has an opacity.

  • id: The block to query.
  • Returns true, if the block has an opacity.
setOpacity(id: DesignBlockId, opacity: number): void

Set the opacity of the given design block. Required scope: ‘layer/opacity’

  • id: The block whose opacity should be set.
  • opacity: The opacity to be set. The valid range is 0 to 1.
getOpacity(id: DesignBlockId): number

Get the opacity of the given design block.

  • id: The block whose opacity should be queried.
  • Returns The opacity.

Blend Mode

Define the blending behavior of a block.

supportsBlendMode(id: DesignBlockId): boolean

Query if the given block has a blend mode.

  • id: The block to query.
  • Returns true, if the block has a blend mode.
setBlendMode(id: DesignBlockId, blendMode: BlendMode): void

Set the blend mode of the given design block. Required scope: ‘layer/blendMode’

  • id: The block whose blend mode should be set.
  • blendMode: The blend mode to be set.
  • Returns
getBlendMode(id: DesignBlockId): BlendMode

Get the blend mode of the given design block.

  • id: The block whose blend mode should be queried.
  • Returns The blend mode.

Full Code

Here’s the full code:

engine.block.supportsOpacity(image);
engine.block.setOpacity(image, 0.5);
engine.block.getOpacity(image);


engine.block.supportsBlendMode(image);
engine.block.setBlendMode(image, 'Multiply');
engine.block.getBlendMode(image);
