oh shit. |

That's just awesome! Pd badly needs a proper zoom function... |
most canvas and item commands are covered. "itemconfigure -font" still to be processed.

done. Now the depth is expressed in steps, and the actual depth is |
- the "Zoom New Windows" setting is now saved to {pd_guiprefs}/default_zoom.conf
- the old .pdsettings::zoom is ignored
- LATER: allow other default_zoom values than 0(100%) or 100(200%)
better keeping immobile the content under the mouse
(and give up trying to do it on scrolling, no working solution was found)

This PR has been brought up to date. I would appreciate it being tested in a variety of circumstances, so that we can insist to have it included. |
|
This PR has been updated to latest master, and debugged for MacOS and Windows. |

I already gave many thumbs up, but I haven't come around to actually test it yet. I will put this on my list and then lobby relentlessly to have this included in Pd 0.55 :) |
Zoom and scroll with the mouse wheel, like most modern software.
The code is adapted from https://wiki.tcl-lang.org/page/Canvas+zooming+using+mousewheel.
It will also allow to clean up the GUI C code from every
IEMGUI_ZOOM()occurrences and logic ;-)Note: the current zoom factor could be reported to the Pd-core side, in order to be saved to file.
