Class ImageModel

java.lang.Object

org.zimowski.bambi.editor.studio.image.ImageModel

All Implemented Interfaces:

ImageConduit

public class ImageModel
extends Object
implements ImageConduit

Represents the underlying image and manages all changes to it. Rotation and zooming are buit in, and all other transformations (filters) are applied from external classes. This model is driven internally by display image struct (displayImage), and two helper buffers (unscaledDisplayImage, unscaledReferenceImage). While not ideally memory efficient design, it is an optimized model given the tradeoff of memory usage vs. runtime performance.

Method Detail

onImageLoad

public void onImageLoad(ImageLoadEvent ev)
                 throws Exception

Throws:

Exception

scale

public void scale(double scalePct)
           throws ScaleViewException

Scales the image to desired percentage.

Parameters:

scalePct - The scale which should be applied to the image.

Throws:

ScaleViewException - This exception is thrown if the scale is out of bounds. Accepted value domain is between 0.1 to 1.0 inclusive.

rotate

public void rotate(ImageTransformListener.RotateDirection direction)

Rotates the image 90 degrees left or right. Preserves any zooming that may have been applied.

Parameters:

direction - - the direction in which the image is rotated.

getImage

public BufferedImage getImage()

Returns a BufferedImage with an applied affinetransform on it.

Returns:

resultImg A BufferedImage with applied affinetransform

twirl

onScale

public void onScale(ScaleEvent ev)

getModifiedImage

public BufferedImage getModifiedImage()

Specified by:

getModifiedImage in interface ImageConduit

Returns:

image on display, unscaled but with all filters applied
