An image based on two-dimensional pixel array.
This is the primary tool for creating in-code images. This class has number of constructors and companion utility methods to aid in creating in-code images in variety of ways. Here's a typical example of using this class to create an in-code image. Note the use of companion object function prepSeq():
object CPAlienImage extends CPArrayImage(
prepSeq("""
| . .
| \/
| (@@)
| g/\_)(_/\e
|g/\(=--=)/\e
| //\\
| _| |_
"""),
(ch, _, _) => ch&C_LIME
)
Value parameters
- data
-
Image data. Note that given data array should not have
nullvalues. - origin
-
The origin of the image like file path or URL.

Compares the receiver object (this) with the argument object (that) for equivalence.
Compares the receiver object (this) with the argument object (that) for equivalence.
Any implementation of this method should be an equivalence relation:
- It is reflexive: for any instance
xof typeAny,x.equals(x)should returntrue. - It is symmetric: for any instances
xandyof typeAny,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any instances
x,y, andzof typeAnyifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue.
If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is usually necessary to override hashCode to ensure that objects which are "equal" (o1.equals(o2) returns true) hash to the same scala.Int. (o1.hashCode.equals(o2.hashCode)).
Value parameters
- that
-
the object to compare against this object for equality.

Detects all background pixels and replaces them with a given pixel returning new image.
Detects all background pixels and replaces them with a given pixel returning new image.
A pixel is considered to be a background pixel when:
- It's satisfies given predicate
- It's not equal to given replacement pixel
- There's a path from it to the edge of the image through background pixels only
For example, a fully enclosed area of the image containing background pixels will NOT be considered a background as there's no path to the edge of the image without crossing a non-background pixels.
Value parameters
- isBgPx
