object Pic extends ShapeAPI
The primary purpose of this companion object of class Pic is to provide methods for
creating new Pic instances: (apply, generate, circle, etc.
There is also a small selection of related utility methods.
This object has an alias in the top-level package o1, so it’s accessible to students simply
via import o1._. The shape-creating methods of this object (such as circle) are also available
as functions in package o1.

- def apply(pathOrURL: String, anchor: Anchor): Pic
Takes an image file path or URL as a string, loads image data from that location, and constructs an anchored Pic from that data.
Takes an image file path or URL as a string, loads image data from that location, and constructs an anchored Pic from that data. Throws an error if the file doesn’t exist or could not be accessed (cf. asTry, asOption).
- pathOrURL
a classpath-relative path or a URL string that starts with "http://" or "https://". Note that the O1Library project exports its
picsfolder, so the example images in that folder can be loaded using just the file name.- anchor
an anchor for the new
Pic- returns
the loaded image (a bitmap)

- def line(from: Pos, to: Pos, color: Color): Pic
Creates a new Pic that portrays a thin line.
Creates a new Pic that portrays a thin line. The line is specified in terms of two Pos objects: imagine drawing a line between the two points on a plane and then cropping the plane to just the part that contains the line.
The line always runs from one corner of the resulting Pic to another. The Anchor of the Pic is at one of the four corners: the one that’s closest to
from.The background is fully transparent.
- from
the “starting point” of the line; the Pic will anchor at the corresponding corner
- to
the “end point” of the line
- color
the color of the line
- returns
a Pic of the line (a vector graphic)

- def show(pic: Pic, background: Color, border: Int): Unit
Displays the given Pic in a minimalistic GUI window.
Displays the given Pic in a minimalistic GUI window. Calling this method repeatedly on the same Pic doesn’t display multiple windows but reuses the existing one. This method is meant only for experimentation and debugging; not for GUI construction (cf. views).
- pic
the image to display; should have a height and width of at least one pixel
- background
the color to appear behind the
Picin the frame (where thePicis transparent)- border
the width of the simple black window frame, in pixels

Creates a new Pic that portrays an isosceles triangle. The triangle’s base is at the bottom of the image and the apex is at the top center. The background is fully transparent.
- width
the width of the triangle’s base, which determines the width of the Pic, too
- height
the height of the triangle, which determines the height of the Pic, too
- color
the color of the triangle
