With the LineArt module, you can work on vector objects in a similar manner to the vector graphic module. In addition to the so-called paths that you know, vector graphic frames in Calamus can, in principle, contain other objects. Another object can be, for example, a raster diagram or the like, built into the vector graphic frame.
At the same time however, LineArt has the new function of being able to merge all objects that exist in Calamus into a vector graphic frame. Additionally, text/line/vector graphic and raster area frames can be used within the vector graphic frame. The objects can be inserted into the frame via the Calamus clipboard, or be inserted into LineArt directly from the page. Since these objects do not necessarily have to be vector objects, those that are not can be worked on in LineArt only in a limited way. The editing is therefore limited to increasing or reducing the size these objects, as well as mirror imaging.
LineArt additionally puts a path editor at your disposal. Paths consist of lines and Bézier curves, and can be created and changed at will. With these basic functions, you can actually provide every kind of vector object. The paths, which are provided in the path editor, are built up into an object. A line type and a filling can be assigned to this object. Therefore all paths of an object possess the same line type and the same filling.
As already described, a path consists of several points which are
connected by lines or Bézier curves. Details on the use of lines and
Bézier curves can be found in the Calamus manual chapter
LineArt examines the structure of the vector graphic to decide
if it is to be cached or not. It is useful to switch the cache
function off if individual objects within complex graphics are to be
shifted or changed in size. Thus only the changed areas are redrawn.
If you work alot in the path editor, then it is useful to start the
cache function. You can switch the cache function on and off for
vector graphic frames at any time in the
Options menu under
Screen output settings. Ultimately, you need to rely on your
own experience with the structure of the graphic.
