About Apply Image

Apply Image lets you blend a layer from a source image into a target image's layer. The images are composited into a single layer. Channel expressions and blend modes are available to composite the layers.

The source image can be scaled automatically to the target image horizontally, vertically or both, avoiding having to size the images equally first.

To blend two images:
  1. Open your target image.
  2. From the Layers Studio, select the layer that you want to blend the source image with.
  3. From the Filters Studio, select Apply Image.
  4. Tap Image and navigate to, then select the source image to import.
  5. Select a Blend Mode to alter how the source image's colours blends with the target image.
  6. (Optional) Set the Opacity level to control how transparent the imported image appears.
  7. (Optional) Tap Scale Horizontal To Fit to disable scaling to fit, i.e. the imported image's native width is used. When enabled, the image is stretched/shrunk to the main image. The Scale Vertical To Fit operates the same but in relation to height.
  8. Tap the check mark to apply.
To use channel expressions:
  1. With the Apply Image context toolbar open, either load an image or change Mode to Current Layer to blend the image with itself.
  2. Navigate to further options on the context toolbar and enable Equations in order to enable channel blending.
  3. Choose a Colour Space to blend.
  4. Now use the available expressions to blend channel information. Some expressions include:
    • Use D+Channel to specify a destination image channel (the original layer), e.g., DB for Destination Blue channel.
    • Use S+Channel to specify a source image channel (the image you have loaded in), e.g., SR for Source Red channel.
    • Use +, -, *, / to add, subtract, multiply or divide respectively, e.g., SR/SG*SB to divide Source Red by Source Green and then multiply by Source Blue.
