This structure is passed to some processing methods such as com.accusoft.imagegear.processing.ImGearRasterProcessing.adjustContrast.

ImGearColorProfileManager

This structure is used with most ImageGear supported formats.

This class does not have public constructors. Instances of ImGearDIB exist only as a member objects of ImGearPage or ImGearROIMask classes.

See PS 3.6 2008, Registry of DICOM data elements table. The names of properties are equivalents to corresponding columns of the table.

In addition to pages the object provides access to document level metadata.

In case of PDF or PS, ImGearDocument object may be associated with an external file.

On adding pages, checks that the new page is not attached to any other document. The remove(Object) method detaches a page from the document. If it is referenced from anywhere else, it remains a valid stand-alone page.

Well-formed page array may contain any number of null entries. An exception is made for the formats where pages are physically continuous (i.e., PDF). Note that setting a page to null is different from removing a page from the document - the former does not change page count, whereas the latter does.

This class must be initialized prior to using any other licensing call when the product is running in evaluation mode.

Contains detailed information about the error that occurred.

This class does not have any public constructors. All instances are created implicitly by overloads of throwError static method.

Each extra channel in image has ImGearExtraChannelInfo object associated with it.

Lookup table contains values for entire input range. Table of values can be accessed directly.

Such LUTs can be used for window levelling of 17-32 bit per channel images.

A LUT is characterized by input depth and output depth; both input and output of the LUT can be signed or unsigned.

Class uses regular color space like RGB, CMYK, etc.

ImGearMetadataHead is a special kind of metadata node with a null Parent field and not more than one child. It is present in every instance of ImGearPage class and ImGearDocument class as class member.

If the page or document has metadata, an instance of ImGearMetadataTree class is attached to the head as a child node. Otherwise, child is null.

ImGearMetadataHead may only be the root of metadata tree. Attempting to attach this class to any node causes ImageGear to throw an exception.

An ImGearMetadataNode can be referenced from one parent node or can be unreferenced. It cannot however be referenced from multiple parents. A node can never refer to itself either directly or indirectly.

Represents container (list) of ImGearMetadataNode instances and provides additional verifications for stored objects. For example, on adding, new MetadataNode is checked to be non-null, stand-alone ( ImGearMetadataNode.getParent == null) and not the same as the top node of the tree to which it is added.

Nodes with different Format values are allowed to be present in the same list. Multiple nodes with the same Tag value are also allowed. The list is not sorted automatically because the order of items may be significant for a particular format.

This class does not have any public constructor. Instances exist only as members of ImGearMetadataTree objects.

Represents metadata tree with structure of any complexity. Similar to ImGearMetadataHead, ImGearMetadataTree, this is a special case of metadata node when getParent() returns null.

An ImGearMultichannelLUT object contains an array of single-channel ImGearLUT class objects.

At the first use of ImGearLicense it automatically looks for a path containing ImageGear Java's igjcommonnative2 native library. It does this by first finding the operating system architecture and then looking for either the environment variable, IMAGE_GEAR_64BIT_PATH, for 64 bits, or IMAGE_GEAR_32BIT_PATH, for 32 bits. These are expected to contain paths to the appropriate folder of native libraries.

If the variable does not exist, it looks in the components of the java.library.path System property. You can set the path to the native libraries to appear in this property in two ways:

1. by adding the path to the operating system's path environment variable
2. by invoking the Java Virtual Machine with the argument -D java.library.path=<path to native binaries>

Setting the operating system's path in the first way will prevent you from using the 32 and 64 bit SDKs simultaneously, since it will always find the version that is first.

The last place it looks is in a bin peer folder of the one the SDK jars were loaded from.

You can specify the native library location programmatically by calling the method, setPath before calling any licensing code, like ImGearLicense.setSolutionName, or after, if the search above does not find a path.

This structure defines the orientation of an image. It works on the image representation and thus allows you to flip and rotate an image without modification of its data (pixels).

It is useful to manipulate the orientation of scanned black-and-white images. Since ImageGear for Java stores such images using lossless compression, this may avoid significant expansion of memory usage while operating on these images.

ImGearARTMark file formats support orientation natively and this allows you to save flipped or rotated images without loss of pixel data or file size enlargement when using compression.

Represents the image and consists of three main parts:

• Image data (pixels)
• Metadata (non-image data)
• Region of interest

The page can be either stand-alone (not referenced from any ImGearDocument classinstance) or attached to a document.

Region of interest ( ImGearROI class) represents free-shape image area (rectangular, non-rectangular or entire space) and specifies a meaningful part of an image. For example, it may be set up for some image processing functions to define the area to which the filter should be applied.

Metadata is non-image data. It is available for most image file formats. In some formats, such as TIFF or PNG, it can be very complex. It can include data of various types and can use a complex structure. ImageGear for Java offers a set of classes designed specifically to manipulate this data consisting of ImGearMetadataNode class, ImGearMetadataNodeList class, ImGearMetadataTree class and their descendants. The metadata for each instance of com.accusoft.imagegear.formats.xmp.pagedtext.ImGearPagedTextXMPMetadata may be accessed through its getMetadata method.

The Image data (or simply, image) is available through the getDIB method. Color Space, channels, width and height are among the major attributes that define the image structure.

This class encapsulates an image pixel and represents the color store for each channel value.

For simplicity, com.accusoft.imagegear.processing.ImGearPixelateFillMethod does not contain any information about channels depths and color space. Therefore pixels that are identical in structure ( ImGearPixel constructor parameters) may belong to images with significantly different channels, structure and color space.

ImGearPage

Specifies image resolution attributes.

The region of interest (ROI) represents freely shaped image area (rectangular, non-rectangular or entire space) that specifies the meaningful part of an image. For example - it may be used to define the area of an image to which an image processing method's filter should be applied.

You can create an ImGearROIMask class object from a binary raster image or from a shape. If the mask is created from a shape, it represents a rasterized version of the shape.

This class does not store a color name, but looks it up from the loaded color books when necessary.

The memory streams are always readable, until ImGearStream.close is called.

This interface specifies baseline features for DICOM display settings. This interface is declared in the Core package, allowing you to attach DICOM Display settings to ImGearPage class and com.accusoft.imagegear.display.ImGearPageDisplay class. However, DICOM Display Settings are only available when the DICOM component is attached. Cast IImGearDICOMDisplaySettings interface to com.accusoft.imagegear.formats.dicom.ImGearDICOMDisplaySettings class to access its features.

com.accusoft.imagegear.formats.dicom.ImGearDICOMDisplaySettings

Specifies color space IDs. All colorspaces listed in this enumeration are supported for internal image storage.

ImageGear also supports colorspaces corresponding to valid combinations of ImGearColorSpaceIDs identifiers. Valid values are composed of a color identifier, such as RGB, Gy, Lab, etc, an optional Alpha and premulultiplied Alpha channel identifiers, and an optional Extra channel identifier. If Premultiplied Alpha bit is set, Alpha bit shall also be set. Only RGB and Gy colorspaces are currently allowed to be combined with Alpha or Premultiplied Alpha.

Currently, only allowsWatermark.
