Zoom level of current edit view?

SCarewe · May 25, 2023, 11:34am

Hello, I would like to be able to know the current zoom level of the edit view, so that I can scale drawn items accordingly:

How can I do this? I wasn’t able to find the approriate method, and ChatGPT is currently at maximum capacity.

In a reporter plugin you get an options dictionary argument with a scale value. Divide your size by that scale to draw in physical units:

size = 12 # = 12 font units
size = 12 / scale # = 12 display points

Yes, but how do I get the scale?

I should specify that I am writing a tool plugin, not a reporter specifically.

Tools are lower-level, there you need to get the scale from the edit view yourself:

github.com

mekkablue/ShowAngledHandles/blob/master/ShowAngledHandles/ShowAngledHandles/MKShowAngledHandles.m#L135


      
          
          
- (void)drawBackgroundForInactiveLayer:(GSLayer *)Layer {
          	// Whatever you draw here will be displayed behind the paths, but for inactive masters.
          }
          
          
- (float)getScale {
          	// [self getScale]; returns the current scale factor of the Edit View UI.
          	// Divide any scalable size by this value in order to keep the same apparent pixel size.
          
          
	if (_editViewController) {
          		return [[_editViewController graphicView] scale];
          	}
          	else {
          		return 1.0;
          	}
          }
          
          
- (void)setController:(NSViewController<GSGlyphEditViewControllerProtocol> *)Controller {
          	// Use [self controller]; as object for the current view controller.
          	_editViewController = Controller;
          }

In Python this should be:

scale = self.editViewController().graphicView().scale()
# or
scale = self.controller.graphicView().scale()

I’m a total idiot. It’s as simple as Font.currentTab.scale. Thanks!
