Though this tool is named for its primary purpose (to generate images) it can also be used to generate PDFs.
In the page layout section, add the blocks. The blocks will be used to combine multiple components into group. Each block will be its own pdf page if the components combined height is within the page height.
Click a component and choose the block that the components belong to. Once that’s done, you can check the actual output by clicking the open PDF button.
Any component that doesn’t belong to a block will not be included in the PDF.
