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.

Concrete methods
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).
Takes an image file path or URL as a string, loads image data from that location, and constructs
a Pic from that data. Anchors the Pic at its center. Throws an error if the file
doesn’t exist or could not be accessed (cf. asTry, asOption).
Takes an image file path or URL as a string and attempts to load image data from that location and construct a BufferedImage from that data. Note that this method does not construct a Pic at all.

Creates a new Pic by setting colors of each individual pixel according to the colors list.
Creates a new Pic by setting colors of each individual pixel according to the colors list.
- Value parameters:
- colors
a sequence of colors, one per pixel, starting from the upper-left corner and continuing to the right and line-by-line towards the bottom
- height
the height, in pixels, of the new
Pic- width
the width, in pixels, of the new
Pic
- Returns:
the new Pic (a bitmap)
Creates a new Pic by applying the given pixel-generating function to each pair coordinates within the new image.
Creates a new Pic by applying the given pixel-generating function to each pair coordinates within the new image.
- Value parameters:
- height
the height, in pixels, of the new
Pic- makeColor
a function that
generatecalls on every pixel location of the newPicto produce the color at that location- width
the width, in pixels, of the new
Pic
- Returns:
the generated Pic (a bitmap)
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).

- Value parameters:
- Returns:
a Pic of the circle (a vector graphic)
- Inherited from:
- ShapeAPI (hidden)
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.
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.
- Value parameters:
- color
the color of the line
- from
the line’s “starting point”; the Pic will anchor at the corresponding corner
- to
the line’s “end point”
- Returns:
a Pic of the line (a vector graphic)
