Frankly, I don't quite understand your problem. Querying the online help for "line style", I getemri hat geschrieben:… but here I am completely stuck trying to figure out something that simple: the manual refers to a Line Style Field without telling you where or how to find it, the "help" that comes with the program gives information that is simply wrong.
3.3.4 The Line Style Field
4.2.1 The Text Style Dialog
4.13 The Style List
4.5.4.2 Line Style
3.7 The Line Editor
3.3.4 explains what a line style field is, and 4.5.4.2 tells you where to find it for vector layers (admittedly, you'll have to consult 4.5.4 to find out what the vector toolbox is). 4.2.1 and 4.13 are additional places where you'll find a line style field (for other purposes), and 3.7 tells you how to edit line styles and how to save presets.
Searching the pdf manual for "Line Style Field" in Acrobat Reader gives similar hits (the contents of the PhotoLine help are the same as the pdf manual).
If there are wrong statements in the manual, I'm sure the developers would be happy to know about them (they usually follow the discussions here, so you may as well post them here in the forum).
Don't get me wrong – the manual certainly is far from perfect. It's a typical example of a manual written by the developers themselves, and as such, it is more of a technical reference than a guide to the program.
