Zooming
Here is how zooming is implemented in different opensource applications.
Table 1-1. Zooming - Incremental from keyboard
| Application | Behaviour
|
| Cinepaint | + to zoom in, - to zoom out, whole number multiples / divisors: 3:1 2:1 1:1 1:2 1:3 1:4, 1 for 1:1
|
| GIMP | + to zoom in, - to zoom out (numpad +/- does not work). 0-2-4-6-9-13-18-25-33-50-67-100%, then by 50% each step, 1 for 1:1 zoom ratio
|
| Inkscape | + - zoom in, - - zoom out (numpad +/- works) - by 50% each
|
| Karbon14 | Ctrl++ - zoom in (factor 1.5), Ctrl+- - zoom out (factor 0.75)
|
| Krita | ???
|
| Scribus | Ctrl++ - zoom in (factor 100%), Ctrl+- - zoom out (factor 100%)
|
| sK1 | F2 and select zoom area for zoom in. F3 - zoom out
|
| Skencil | < - zoom out (factor 0.5), > - zoom in (factor 2)
|
| Blender | ???
|
| Audacity | Ctrl+1 - zoom in, Ctrl+2 - zoom normal, Ctrl+3 - zoom out
|
Table 1-2. Zooming - Incremental with mouse
| Application | Behaviour
|
| Cinepaint | currently none
|

|
| Inkscape | Ctrl + mouse wheel, by 50% each rotation step
|
| Karbon14 | ???
|
| Krita | ???
|
| Scribus | Ctrl + mouse wheel, by 100% each rotation step
|
| sK1 | Shift + mouse wheel
|

|
Table 1-3. Zooming - By presets
| Application | Behaviour
|
| Cinepaint | <image menu> -> View -> Pan Zoom Window, 5 free selectable presets, remember with ctrl + #
|
| GIMP | in menu View - Scale: incremental zoom out (-), incremental zoom in (+), fit image to window (Shift+Ctrl+E), Fit window to image (Ctrl+E), 16:1, 8:1, 4:1 (Alt+4), 2:1 (Alt+2), 1:1 (1), 1:2, 1:4, 1:8, 1:16, Other... . Presets are configurable
|
| Inkscape | 1 - 1:1, 2 - 1:2, 3 - zoom to selection, 4 - zoom to drawing, 5 - zoom to page, 6 - zoom to page width, ` - previous zoom, Shift + ` - next zoom
|
| Karbon14 | zoom to page width, zoom fit whole page, 25%, 50%, 100%, 200%, 300%, 400%, 800%
|
| Krita | ???
|
| Scribus | Ctrl + 0 - fit page in window, Ctrl + 1 - zoom to 100%, rest of possible presets are configurable
|
| sK1 | ???
|
| Skencil | Menu View: 100%, zoom out (<), zoom in (>), submenu Zoom with some predefined zoom factors, fit drawing to window (Shift + F4), fit selection to window (Ctrl + F4), fit page to window (F4), restore previous view (F3)
|
| Blender | ???

Table 1-4. Zooming - From menu/toolbar
| Application | Behaviour
|
| Cinepaint | <image menu> -> View -> Zoom -> [16:1,8:1,4:1,2:1,1:1,1:2,4:1,8:1,16:1]
|
| GIMP | in menu View - Scale: incremental zoom out (-), incremental zoom in (+), fit image to window (Shift+Ctrl+E), Fit window to image (Ctrl+E), 16:1, 8:1, 4:1 (Alt+4), 2:1 (Alt+2), 1:1 (1), 1:2, 1:4, 1:8, 1:16, Other... . Presets are configurable
|
| Inkscape | Presets are present in View menu, Commands toolbar contains zoom to selection/drawing/page buttons only, both incremental zoom in/out and presets buttons are available in context sensitive toolbar for Zoom tool
|
| Karbon14 | presets are present in View menu and View toolbar
|
| Krita | ???
|
| Scribus | Navigation toolbar in the bottom has percentage spinbox, 1:1 button and -/+ buttons - incremental by 100%
|
| sK1 | ???
|
| Skencil | Presets in menu View, Zoom tool available in toolbar or via the View menu as Zoom area
|
| Blender | ???
|
| Audacity | ???
|
Table 1-5. Zooming - by a zoom tool
| Application | Behaviour
|
| Cinepaint | from Toolbox, LMB to zoom in, Shift + LMB to zoom out
|
| GIMP | Available from toolbox and Tools menu, no hotkey by default, zoom in by default, LMB to zoom in, Ctrl+LMB to zoom out, Drag LMB to zoom to selection
|
| Inkscape | Available from toolbox or Z hotkey, zoom in by default, LMB to zoom in, Shift+LMB to zoom out, Drag LMB to zoom to selection
|
| Karbon14 | available from toolbox, LMB to zoom in, RMB to zoom out, Drag LMB to zoom to selection
|
| Krita | ???
|
| Scribus | Available from toolbox or Z hotkey, LMB to zoom in, Shift+LMB to zoom out— +/- 25% each step, Drag LMB to zoom to selection
|
| sK1 | ???
|
| Skencil | Zoom tool in the toolbar or from menu: LMB to zoom in, Ctrl+LMB to zoom out— factor of 2 each step, Drag LMB to zoom to selection

Panning
Here is how panning is implemented in different opensource applications.
Table 2-1. Panning - from keyboard
| Application | Behaviour
|
| Cinepaint | none
|
| GIMP | in Zoom tool mode arrow keys scroll view in respective directions, Shift+arrow keys scroll with a larger step, Ctrl+arrow keys scroll to borders of an image
|
| Inkscape | in any mode Ctrl+arrow keys scroll view in respective directions
|
| Karbon14 | ???
|
| Krita | ???
|
| Scribus | Page Up/Down scroll up or down respectively
|
| sK1 | ???
|
| Skencil | Scroll up/down with PageUp/PageDown or mouse wheel. Otherwise use scrollbars
|
| Blender | ???
|
| Audacity | ???
|
Table 2-2. Panning - with a mouse
| Application | Behaviour
|
| Cinepaint | Drag MMB to pan around
|
| GIMP | Either press Spacebar and pan with a mouse, or Drag MMB to pan around. This is a configurable behaviour.
|
| Inkscape | Drag MMB to pan around
|
| Karbon14 | ???
|
| Krita | ???
|
| Scribus | Push Space down, hold it and pan around with LMB
|

Resizing
Here is how resizing is implemented in different opensource applications.
Table 3-1. Resizing - with mouse
| Application | Behaviour
|
| Cinepaint | ???
|
| GIMP | Ctrl keeps ratio (interactive Resize Tool)
|
| Inkscape/SVN | Draging the scale handles with Alt now scales selection by an integer factor, i.e. up to 2, 3, 4, etc. times the original size or
down to 1/2. 1/3, 1/4, etc. of the original size. Shift transforms selection around the center, Ctrl keeps ratio.
|
| Karbon14 | Alt and Ctrl aren't used, Shift keeps ratio.
|
| Krita | ???
|
| Scribus | Alt isn't used, Shift transforms the object to a square, Ctrl keeps ratio.
|
| sK1 | As of SVN trunk, ratio is always kept, when you drag corner handles
