Description Tatu Portin 2005-12-09 22:56:03 UTC
There should be option to show golden section and center-line guides while 
cropping. Especially golden section guides would be good, because it would be 
lot faster for computer to calculate correct golden section than by hand, 
which I'm doing by now.

This boils down to bug #156858, doesn't it?
Comment 2 Michael Schumacher 2005-12-12 11:53:26 UTC
IMO it doesn't - if I got the reporter's intention right, the guides discussed
here are supposed to appear inside the crop frame and are thus more like
crosshairs than a guide.
Comment 3 Tatu Portin 2005-12-12 17:01:22 UTC
Yes, the intent was like crosshairs. With those crosshairs you can adjust the 
size and position of the crop frame, so that the golden section fall to right 
place. 
Like, if there was a person in the picture, you would place his/her centerline 
on the golden section crosshair, if there was a portrait, you could place side 
of his/her face parallel with the golden section crosshair.  
Golden section has been used as a guide to arrange settings in various 
pictorial arts for centuries. 
Look at these Wikipedia articles, especially Rule of Thirds.

Comment 4 Michael Schumacher 2005-12-12 21:32:30 UTC
Confirming. This would be a nice addition for the rectangle tool, so that all
tools derived from it can get this (right now, the new rectangualr selection and
the crop tool).

Adds a guide option to the crop tool

Here is an implementation for this, adding visual guides inside the crop rectangle. Guides available : center lines, rule of thirds, golden sections.

I'm not sure whether it would be useful for the selection tools too.

Adds a guide option to the rectangle tool

Same as previous one, but now all rectangle tools get the option (crop + rect select + ellipse select).
