Image (MultimediaLib 2020.3.3 API)

All Known Implementing Classes:

AWTImage, GDXImage, TeaImage
```
public interface Image
```
Represents an image based on raster graphics. Images be loaded from PNG or JPEG files using a MediaLoader.
Instances of an Image may represent either the entire underlying image, or a rectangular region within the source image. That is, instances do not always map directly to an image file. This aligns with the common practice of including multiple images within a larger image, either as a sprite sheet (for 2D graphics) or a texture (for 3D graphics).

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`Image`	`extractRegion(Rect region)`	Returns a new `Image` instance that is based on the same source image, but only contains the specified rectangular region within the source image.
`int`	`getAlpha(int x, int y)`	Returns the alpha of a pixel within the image.
`ColorRGB`	`getColor(int x, int y)`	Returns the RGB color value of a pixel within the image.
`default int`	`getHeight()`
`Rect`	`getRegion()`
`default int`	`getWidth()`

- Method Detail
  - getRegion
```
Rect getRegion()
```
  - getWidth
```
default int getWidth()
```
  - getHeight
```
default int getHeight()
```
  - extractRegion
```
Image extractRegion(Rect region)
```
    Returns a new Image instance that is based on the same source image, but only contains the specified rectangular region within the source image.
  - getColor
```
ColorRGB getColor(int x,
                  int y)
```
    Returns the RGB color value of a pixel within the image. This does not include the pixel's alpha value even if the image does support transparency. The alpha value can be retrieved separately using getAlpha(int, int).
  - getAlpha
```
int getAlpha(int x,
             int y)
```
    Returns the alpha of a pixel within the image. The returned value is between 0 (fully transparent) and 100 (fully opaque).
