Types ¶
type Action ¶
type Action interface {
Call() string
ApplyTo(vg.Canvas)
// contains filtered or unexported methods
}
Action is a vector graphics action as defined by the vg.Canvas interface. Each method of Canvas has a corresponding Action type.
type Canvas ¶
type Canvas struct {
// Actions holds a log of all methods called on
// the canvas.
Actions []Action
// KeepCaller indicates whether the Canvas will
// retain runtime caller location for the actions.
// This includes source filename and line number.
KeepCaller bool
// contains filtered or unexported fields
}
Canvas implements vg.Canvas operation serialization.
func (*Canvas) FillString ¶
FillString implements the FillString method of the vg.Canvas interface.
func (*Canvas) Pop ¶
func (c *Canvas) Pop()
Pop implements the Pop method of the vg.Canvas interface.
func (*Canvas) Push ¶
func (c *Canvas) Push()
Push implements the Push method of the vg.Canvas interface.
func (*Canvas) ReplayOn ¶
ReplayOn applies the set of Actions recorded by the Canvas onto the destination Canvas.
func (*Canvas) SetLineDash ¶
SetLineDash implements the SetLineDash method of the vg.Canvas interface.
func (*Canvas) SetLineWidth ¶
SetLineWidth implements the SetLineWidth method of the vg.Canvas interface.
type Comment ¶
type Comment struct {
Text string
// contains filtered or unexported fields
}
Comment implements a comment mechanism.

Push corresponds to the vg.Canvas.Push method.
type Rotate ¶
type Rotate struct {
Angle float64
// contains filtered or unexported fields
}
Rotate corresponds to the vg.Canvas.Rotate method.
type Scale ¶
type Scale struct {
X, Y float64
// contains filtered or unexported fields
}
Scale corresponds to the vg.Canvas.Scale method.
type SetColor ¶
SetColor corresponds to the vg.Canvas.SetColor method.
type SetLineDash ¶
type SetLineDash struct {
Dashes []vg.Length
Offsets vg.Length
// contains filtered or unexported fields
}
SetLineDash corresponds to the vg.Canvas.SetLineDash method.
