If a property is not defined for a particular image, this method returns the UndefinedProperty object. If the properties for this image are not yet known, this method returns nulland the ImageObserver object is notified later. The property name "comment" should be used to store an optional comment which can be presented to the application as a description of the image, its source, or its author.
Parameters: name - a property name. Returns: the value of the named property. Throws: NullPointerException - if the property name is null.
A new Image object is returned which will render the image at the specified width and height by default. The new Image object may be loaded asynchronously even if the original source image has already been loaded completely.
If either width or height is a negative number then a value is substituted to maintain the aspect ratio of the original image dimensions. If both width and height are negative, then the original image dimensions are used. Parameters: width - the width to which to scale the image. Returns: a scaled version of the image. Throws: IllegalArgumentException - if width or height is zero. Since: JDK1. This includes any pixel data that is being cached for rendering to the screen as well as any system resources that are being used to store data or pixels for the image if they can be recreated.
The image is reset to a state similar to when it was first created so that if it is again rendered, the image data will have to be recreated or fetched again from its source. Examples of how this method affects specific types of Image object: BufferedImage objects leave the primary Raster which stores their pixels untouched, but flush any information cached about those pixels such as copies uploaded to the display hardware for accelerated blits.
Image objects created by the Component methods which take a width and height leave their primary buffer of pixels untouched, but have all cached information released much like is done for BufferedImage objects. VolatileImage objects release all of their pixel resources including their primary copy which is typically stored on the display hardware where resources are scarce. These objects can later be restored using their validate method.
Image objects created by the Toolkit and Component classes which are loaded from files, URLs or produced by an ImageProducer are unloaded and all local resources are released. These objects can later be reloaded from their original source as needed when they are rendered, just as when they were first created.
This allows programmers to find out more runtime information on the specific Image object that they have created. For example, the user might create a BufferedImage but the system may have no video memory left for creating an image of that size on the given GraphicsConfiguration, so although the object may be acceleratable in general, it does not have that capability on this GraphicsConfiguration.
Parameters: gc - a GraphicsConfiguration object. A value of null for this parameter will result in getting the image capabilities for the default GraphicsConfiguration. Returns: an ImageCapabilities object that contains the capabilities of this Image on the specified GraphicsConfiguration.
Since: 1. This priority hint is used to compare to the priorities of other Image objects when determining how to use scarce acceleration resources such as video memory.
When and if it is possible to accelerate this Image, if there are not enough resources available to provide that acceleration but enough can be freed up by de-accelerating some other image of lower priority, then that other Image may be de-accelerated in deference to this one. Images that have the same priority take up resources on a first-come, first-served basis. Parameters: priority - a value between 0 and 1, inclusive, where higher values indicate more importance for acceleration.
A value of 0 means that this Image should never be accelerated. Other values are used simply to determine acceleration priority relative to other Images.All implementations of javax. These are the "standard" GIF plug-ins, meaning those that are included in the JRE, as distinct from those included in standard extensions, or 3rd party plug-ins.
The following notes and metadata specification apply to the standard plug-ins. Writing GIF images The GIF image writer plug-in guarantees lossless writing for images which meet the following requirements: the number of bands is 1; the number of bits per sample is not greater than 8; the size of a color component is not greater than 8.
By default the GIF writer plug-in creates version "89a" images. A global color table is written to the output stream if one of the following conditions is met: stream metadata containing a GlobalColorTable element is supplied; a sequence is being written and image metadata containing a LocalColorTable element is supplied for the first image in the sequence; image metadata is not supplied or does not contain a LocalColorTable element.
In the first case the global color table in the stream metadata is used, in the second the local color table in the image metadata is used, and in the third a global color table is created from the ColorModel or SampleModel of the first image.
A local color table is written to the output stream only if image metadata containing a LocalColorTable element is supplied to the writer, or no image metadata is supplied to the writer and the local color table which would be generated from the image itself is not equal to the global color table. A Graphic Control Extension block is written to the output stream only if image metadata containing a GraphicControlExtension element is supplied to the writer, or no image metadata is supplied and the local color table generated from the image requires a transparent index.
Application, Plain Text, and Comment Extension blocks are written only if they are supplied to the writer via image metadata. The writing of interlaced images can be controlled by the progressive mode of the provided ImageWriteParam instance. The mapping of standard metadata format to the GIF native stream and image metadata formats is given in the tables here. That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples.

A simple container class to aggregate an image, a set of thumbnail preview images, and an object representing metadata associated with the image. A superclass of all classes describing how streams should be decoded or encoded. A class containing static convenience methods for locating ImageReader s and ImageWriter s, and performing simple encoding and decoding. A class that allows the format of an image in particular, its SampleModel and ColorModel to be specified in a convenient manner.
An exception class used for signaling run-time failure of reading and writing operations. An interface to be implemented by objects that can determine the settings of an IIOParam object, either by putting up a GUI to obtain values from a user, or by other means.
An interface providing metadata transcoding capability. An abstract superclass for parsing and decoding of images. An abstract superclass for encoding and writing images.Images can be resized as they are loaded for example to reduce the amount of memory consumed by the image.
The application can specify the quality of filtering used when scaling, and whether or not to preserve the original image's aspect ratio.
If the passed string is not a valid URL, but a path instead, the Image is searched on the classpath in that case. Use ImageView for displaying images loaded with this class. The same Image instance can be displayed by multiple ImageView s. If not initialized or set to true a better quality filtering will be used, otherwise a faster but lesser quality filtering will be used.

Gets the height of the bounding box within which the source image is resized as necessary to fit. Gets the width of the bounding box within which the source image is resized as necessary to fit.
Indicates whether to preserve the aspect ratio of the original image when scaling to fit the image within the bounding box provided by width and height. Indicates whether to use a better quality filtering algorithm or a faster one when scaling this image to fit within the bounding box provided by width and height. The image width or 0 if the image loading fails.
While the image is being loaded it is set to 0. The image height or 0 if the image loading fails. The exception which caused image loading to fail. Contains a non-null value only if the error property is set to true. Construct a new Image with the specified parameters.
The url without scheme is threated as relative to classpath, url with scheme is treated accordingly to the scheme using URL. The approximate percentage of image's loading that has been completed. See preserveRatio for information on interaction between image's requestedWidthrequestedHeight and preserveRatio attributes. If set to trueit affects the dimensions of this Image in the following way: If only width is set, height is scaled to preserve ratio If only height is set, width is scaled to preserve ratio If both are set, they both may be scaled to get the best fit in a width by height rectangle while preserving the original aspect ratio The reported width and height may be different from the initially set values if they needed to be adjusted to preserve aspect ratio.
If unset or set to falseit affects the dimensions of this ImageView in the following way: If only width is set, the image's width is scaled to match and height is unchanged; If only height is set, the image's height is scaled to match and height is unchanged; If both are set, the image is scaled to match both.
Cancels the background loading of this image. Has no effect if this image isn't loaded in background or if loading has already completed. If this method returns null then this image does not support reading at this time.This class relies on the data fetching and setting methods of Rasterand on the color characterization methods of ColorModel.
Raster getData Returns the image as one large tile. Graphics getGraphics This method returns a Graphics2Dbut is here for backwards compatibility. String  getPropertyNames Returns an array of names recognized by getProperty String or nullif no property names are recognized. ImageProducer getSource Returns the object that produces the pixels for the image.
Point  getWritableTileIndices Returns an array of Point objects indicating which tiles are checked out for writing. This type is only used as a return value for the getType method. The image has a DirectColorModel without alpha. When data with non-opaque alpha is stored in an image of this type, the color data must be adjusted to a non-premultiplied form and the alpha discarded, as described in the AlphaComposite documentation.
The image has a DirectColorModel with alpha. The color data in this image is considered not to be premultiplied with alpha.How to Run Spring Boot Application in Docker
When this type is used as the imageType argument to a BufferedImage constructor, the created image is consistent with images created in the JDK1. The color data in this image is considered to be premultiplied with alpha. There is no alpha. The image has a DirectColorModel.
The image has a ComponentColorModel. The image has a ComponentColorModel with alpha. The byte data is interleaved in a single byte array in the order A, B, G, R from lower to higher byte addresses within each pixel. This image has a DirectColorModel. The image has an IndexColorModel without alpha. Images with 2 or 4 bits per pixel may be constructed via the BufferedImage constructor that takes a ColorModel argument by supplying a ColorModel with an appropriate map size.
When color data is stored in an image of this type, the closest color in the colormap is determined by the IndexColorModel and the resulting index is stored. Approximation and loss of alpha or color components can result, depending on the colors in the IndexColorModel colormap.
If the color model has 1 or 2 entries, the image will have 1 bit per pixel. If it has 3 or 4 entries, the image with have 2 bits per pixel. If it has between 5 and 16 entries, the image will have 4 bits per pixel.
Otherwise, an IllegalArgumentException will be thrown. If the number and types of bands in the SampleModel of the Raster do not match the number and types required by the ColorModel to represent its color and alpha components, a RasterFormatException is thrown.
How to use Java 8 Encode (Decode) an Image to Base64
This method can multiply or divide the color Raster data by alpha to match the alphaPremultiplied state in the ColorModel. Parameters: cm - ColorModel for the new image raster - Raster for the image data isRasterPremultiplied - if truethe data in the raster has been premultiplied with alpha.
Throws: RasterFormatException - if the number and types of bands in the SampleModel of the Raster do not match the number and types required by the ColorModel to represent its color and alpha components. Returns: the image type of this BufferedImage. Returns: the WriteableRaster of this BufferedImage.
Returns null if there is no alpha channel associated with the ColorModel in this image. This method assumes that for all ColorModel objects other than IndexColorModelif the ColorModel supports alpha, there is a separate alpha channel which is stored as the last band of image data.
If the image uses an IndexColorModel that has alpha in the lookup table, this method returns null since there is no spatially discrete alpha channel.
This method creates a new WritableRasterbut shares the data array. Color conversion takes place if this default model does not match the image ColorModel. There are only 8-bits of precision for each color component in the returned data when using this method.He looked like a man who had lately had a preview of Hell's inverted pleasures. She recalled all that now as she sat in the little theatre waiting for the preview of her picture to begin.
Because of such a plan the matters of review and preview take on vital significance. Complexity Complexity sorts synonyms based on their difficulty. Adjust it higher to choose from words that are more complex. Length Length ranks your synonyms based on character count.
Informal Informal words should be reserved for casual, colloquial communication. What does Tis the Season mean. Important as is the review, the preview or assignment is equally vital.
