Re: [Gimp-developer] Smooth Zoom

[Bot Obi <botobi gmail com>]

Hi Jason,

 

that's exactly the point! The zoom steps should be proportional to the current zoom level. And IMHO they could easily be as small as one hundredth of the current zoom level (e.g. 1%-steps at 100%).

For me the super-duper solution was to have two configurable zoom steps in the presets: 1) a "fine zoom" step and 2) a "standard zoom" step. The zoom-step-values would represent a fraction of the current zoom level (e.g. "100" for "fine zoom" and "10"  for standard zoom). The existing functions/macros "view-zoom-in" and "view-zoom-out" would use the zoom step defined for "standard zoom" and a new pair of functions/macros e.g. "view-zoom-in-accurate" and "view-zoom-out-accurate" would use the zoom step defined for "fine zoom".

By assigning the macros to the appropriate keys or mouse actions everybody could adapt the zoom behaviour exactly to his/her needs. E.g. by using the currently defined key shortcut presets "+" for "view-zoom-in" and "-" for "view-zoom-out" and adding the new shortcuts "shift +" for "view-zoom-in-accurate" and "shift -" for "view-zoom-out-accurate" would allow to quickly change the zoom level by a large amount using +/- keys and then allowing to adjust it very accurately by using "shift" together with the +/- keys.

Very simple, very comfortable, very accommodative!

Why is there no possibility to zoom in and out just the same way like
panning? Why are the zoom steps for "view-zoom-in" and "view-zoom-out"
so big?

I think Bot Obi is specifically referring to the preset "zoom steps". They seem to be fixed at: 12.5%, 25%, 50%, 66.7%, 100%, 150%, 200%, 300%, etc. regardless of the method used to zoom in and out (zoom tool, keyboard + arrows, keyboard + scrollwheel)

I have Photoshop 7 running in Wine. It has the same or very similar preset steps using the Zoom tool. However, using the keyboard shortcut Ctrl + Alt + scroll (or Ctrl + Alt + Shift + scroll) you get a sort of proportional step. When you are zoomed out below 50% the steps go from 5% down to 3% and 2%. Above 100% the steps go from 10% to 14%. Beyond 300% the steps are a little over 30%.

So the steps are something like 10% of the current zoom state rather than the fixed steps. It makes for a very “smooth” zooming sensation.

Granted, Photoshop 7 was released in 2002. At work I have CS3 and will have to experiment with that when I get to the office.

It certainly would be cool to have this proportional step zoom instead of the preset steps. Or possibly as an option. Or maybe just available via the keyboard shortcut. I wouldn't be surprised if some workflows relied on the fixed steps... for pixel-perfect icon designing maybe?

Hope this info is helpful.
