Bounds value problem

Scripting
1

The layer has two nodes independently.
and I want to calculate the bounds size and position through the following script.
But it feedback the wrong values, which can’t calculate the values including the two independent nodes.

layer =  Glyphs.font.glyphs['space'].layers[0]
print(layer.bounds.size.width, layer.bounds.size.height)
print(layer.bounds.origin.x, layer.bounds.origin.y)

The layer bounds do not include single nodes, since they are removed on export. If you want the bounds of all selected nodes, use the selectionBounds.

3

so, what is the ‘select all’ of layers function?

I am not sure what you mean. Do you want to select all nodes on the current layer with a script?

5

yes, thanks.

You can use this:

for path in Layer.paths:
	path.selected = True

If you also want to select anchors:

for anchor in Layer.anchors:
	anchor.selected = True

And to selecting all components:

for component in Layer.components:
	component.selected = True

got it, thanks a lot:)

Adding the section one by one can be VERY slow. So this is much faster:

newSelection = []
for path in Layer.paths:
	newSelection.extend(path.nodes)
newSelection.extend(Layer.anchors)
for component in Layer.components:
	newSelection.append(component)
Layer.selection = newSelection

But what are you trying to do? What do you need the bounds for?

You could write a function that gets the bound from all nodes:

from Foundation import NSMinX, NSMinY, NSMaxX, NSMaxY

minX = 30000
minY = 30000
maxX = -30000
maxY = -30000

layerBounds = Layer.bounds
minX = min(minX, NSMinX(layerBounds))
minY = min(minY, NSMinY(layerBounds))
maxX = max(maxX, NSMaxX(layerBounds))
maxY = max(maxY, NSMaxY(layerBounds))

for path in Layer.paths:
	pathBounds = path.fastBounds()
	minX = min(minX, NSMinX(pathBounds))
	minY = min(minY, NSMinY(pathBounds))
	maxX = max(maxX, NSMaxX(pathBounds))
	maxY = max(maxY, NSMaxY(pathBounds))
print(minX, minY, maxX, maxY)

The first is what I need.
Thanks:)

Depending what you are trying to do, I would try to not change the state of the layers when running the script.
