Interface Pixmap<PX>

Type Parameters:
PX - The type of the pixel being managed by the Pixmap.
All Superinterfaces:
HeightAccessor, WidthAccessor
All Known Subinterfaces:
Pixmap.PixmapBuilder<PX,B>, Pixmap.PixmapProperty<PX>, RgbPixmap, RgbPixmap.RgbPixmapBuilder, RgbPixmap.RgbPixmapProperty
All Known Implementing Classes:
RgbPixmapBuilderImpl, RgbPixmapImpl
public interface Pixmap<PX> extends WidthAccessor, HeightAccessor
A pixmap represents the data of a two dimensional image. The pixels may be accessed by providing an x and a y position and, depending on the sub-types, a pixel my be represented by an RgbPixel (as of the Pixmap type).

  • Method Details

    • getPixels

      PX[][] getPixels()
      Returns the two dimensional pixels array representing the pixmap.
      Returns:
      The pixmap array.

    • getWidth

      int getWidth()
      Retrieves the width of the Pixmap.
      Specified by:
      getWidth in interface WidthAccessor
      Returns:
      The width of the Pixmap

    • getHeight

      int getHeight()
      Retrieves the height of the Pixmap.
      Specified by:
      getHeight in interface HeightAccessor
      Returns:
      The height of the Pixmap

    • getPixelAt

      PX getPixelAt(int aPosX, int aPosY)
      Retrieves a pixel at a given position.
      Parameters:
      aPosX - The x position for the pixel to be retrieved.
      aPosY - The y position for the pixel to be retrieved.
      Returns:
      The according pixel
      Throws:
      IndexOutOfBoundsException - in case the index is out of bounds.

    • hasPixelAt

      default boolean hasPixelAt(int aPosX, int aPosY)
      Tests whether there is a pixel at a given position.
      Parameters:
      aPosX - The x position for the pixel to be tested.
      aPosY - The y position for the pixel to be tested.
      Returns:
      True if we have a pixel at this position.
      Throws:
      IndexOutOfBoundsException - in case the index is out of bounds.
