Geometry is essential for the paper publishing. In GN4 we define the term "geometry" as shapes, that you associate to content. Geometry rules the flow of text and appearance of images on pages.
The geometry is represented by set of text frames. An article element that appears on a page is linked to the frames and therefore contains a geometry. Such geometry can be also stored locally - an article element is not linked to any page, but still contains a geometry and can be used as a template.
You can display the geometry of text in the WYSIWYG pane of Ted4 and in the Preview pane of the Article editor in the browser.
When on a page you change the geometry of a linked text, the change is automatically displayed in Ted4.
Geometry is not required for Web publishing or any other channel, different than paper.
Image geometry: in a wider sense, a geometry is also assigned to images, as a crop and size box, with x, y, height and width. If the height and width are the same as for the original image, the image is neither cropped nor sized.
You can display the geometry of a image in the WYSIWYG pane of Ted4, if the image is part of an article.
