The 'Topaz: Illustration Upscale' workflow is designed to enhance and upscale illustrations using the Topaz model, a specialized tool for improving image resolution while maintaining color accuracy and stylistic elements. This workflow is particularly useful for artists and designers who need to upscale digital illustrations without losing the original artwork's integrity. The process begins with loading an image using the LoadImage node, which is then processed by the TopazImageEnhance node to apply upscale algorithms. The ImageScaleBy node is used to adjust the image size according to desired specifications, while the GetImageSize node ensures the dimensions meet the required output. Finally, the SaveImage node saves the enhanced illustration, ready for use in high-resolution projects.
