With layered images, you can create your own visual product configurator. Instead of having one image for every configuration, you can combine multiple layers into one combined image. This approach allows you to create complex configurations that are easy to set up and load quickly.
Layered images are images that are stacked on top of each other. You can see every image as a layer. By controlling which layer is visible and which is not, you can build up a complete and unique image with layers, depending on which layers you show.
When uploading layered images, it's essential that they are uploaded in a PNG format with an opaque background because this way, when they overlap, their opaque parts are filled by the layers below.
Layering, or stacking, the images is a much more efficient way of displaying configurations than adding images for each configuration. Let's say we have a product configurator with 4 parameters, and each parameter has 4 options. These approaches make a huge difference:
- Layered = 4 + 4 + 4 + 4 = 16 images needed
- Individual = 4 * 4 * 4 * 4 = 256 images needed
See this tutorial on how to create a product configurator, which demonstrates how you can best apply layered images.
There are two ways to load image layers into your calculator. You either use the "Use Formula for Images" or not. If you don't, you can add images manually.
When you use a formula to generate images, you can use Datasheets or Tables to return a matrix (spreadsheets data structure). This matrix is used to render the images. Make sure you specify the Image and Formula column. When you've set up your Table, the formula is as simple as this:
