ClippedImagePrototype class

Implementation of {@link AbstractImagePrototype} for a clipped image. This class is used internally by the image bundle generator and is not intended for general use. It is subject to change without warning.

class ClippedImagePrototype extends AbstractImagePrototype {

 static final ClippedImageImpl _impl = new ClippedImageImpl(); //GWT.create(ClippedImageImpl.class);

 final int height;
 final int left;
 final int top;
 final SafeUri url;
 final int width;

 ClippedImagePrototype(this.url, this.left, this.top, this.width, this.height);


 void applyTo(Image image) {
   image.setSafeUrlAndVisibleRect(url, left, top, width, height);
 }


 void applyToImageElement(dart_html.ImageElement imageElement) {
   _impl.adjust(imageElement, url, left, top, width, height);
 }


 dart_html.ImageElement createElement() {
   return _impl.createStructure(url, left, top, width, height) as dart_html.ImageElement;
 }


 Image createImage() {
   return new Image.fromSafeUriAndMeasure(url, left, top, width, height);
 }


 SafeHtml getSafeHtml() {
   return _impl.getSafeHtml(url, left, top, width, height);
 }
}

Constructors

new ClippedImagePrototype(SafeUri url, int left, int top, int width, int height) #

Creates a new Object instance.

Object instances have no meaningful state, and are only useful through their identity. An Object instance is equal to itself only.

Methods

void applyTo(Image image) #

Transforms an existing {@link Image} into the image represented by this prototype.

@param image the instance to be transformed to match this prototype

docs inherited from AbstractImagePrototype

void applyTo(Image image) {
 image.setSafeUrlAndVisibleRect(url, left, top, width, height);
}

void applyToImageElement(ImageElement imageElement) #

Transforms an existing {@link ImagePrototypeElement} into the image represented by this prototype.

@param imageElement an <code>ImagePrototypeElement</code> created by

     {@link #createElement()}

docs inherited from AbstractImagePrototype

void applyToImageElement(dart_html.ImageElement imageElement) {
 _impl.adjust(imageElement, url, left, top, width, height);
}

ImageElement createElement() #

Creates a new {@link Element} based on the image represented by this prototype. The DOM structure may not necessarily a simple <code><img></code> element. It may be a more complex structure that should be treated opaquely.

@return the <code>ImagePrototypeElement</code> corresponding to the image

    represented by this prototype

docs inherited from AbstractImagePrototype

dart_html.ImageElement createElement() {
 return _impl.createStructure(url, left, top, width, height) as dart_html.ImageElement;
}

Image createImage() #

Creates a new {@link Image} instance based on the image represented by this prototype.

@return a new {@link Image} based on this prototype

docs inherited from AbstractImagePrototype

Image createImage() {
 return new Image.fromSafeUriAndMeasure(url, left, top, width, height);
}

String getHtml() #

inherited from AbstractImagePrototype

Gets an HTML fragment that displays the image represented by this prototype. The HTML returned is not necessarily a simple <code><img></code> element. It may be a more complex structure that should be treated opaquely. <p> The default implementation calls {@link #getSafeHtml()}.

@return the HTML representation of this prototype

String getHtml() {
 return getSafeHtml().asString();
}

SafeHtml getSafeHtml() #

@return the HTML representation of this prototype

docs inherited from AbstractImagePrototype

SafeHtml getSafeHtml() {
 return _impl.getSafeHtml(url, left, top, width, height);
}
