ImageTypeSpecifier.createInterleaved(ColorSpace colorSpace,
int[] bandOffsets,
int dataType,
boolean hasAlpha,
boolean isAlphaPremultiplied)
Returns a specifier for an interleaved image format that will
use a

ImageTypeSpecifier.createPacked(ColorSpace colorSpace,
int redMask,
int greenMask,
int blueMask,
int alphaMask,
int transferType,
boolean isAlphaPremultiplied)

SampleModel to store each pixel packed into in a
single byte, short, or int. |
ImageTypeSpecifier |
IIOParam.getDestinationType()
Returns the type of image to be returned by the read, if one
was set by a call to
setDestination(ImageTypeSpecifier), as an
ImageTypeSpecifier. |
ImageTypeSpecifier |
ImageReader.getRawImageType(int imageIndex)
Returns an
ImageTypeSpecifier indicating the
SampleModel and ColorModel which most
closely represents the "raw" internal format of the image. |
| Modifier and Type | Method and Description |
|---|---|
abstract Iterator<ImageTypeSpecifier> |
ImageReader.getImageTypes(int imageIndex)

Iterator containing possible image
types to which the given image may be decoded, in the form of
ImageTypeSpecifierss. |
| Modifier and Type | Method and Description |
|---|---|
IIOMetadata |
ImageTranscoder.convertImageMetadata(IIOMetadata inData,
ImageTypeSpecifier imageType,
ImageWriteParam param)
Returns an
IIOMetadata object that may be used for
encoding and optionally modified using its document interfaces
or other interfaces specific to the writer plug-in that will be
used for encoding. |
abstract IIOMetadata |
ImageWriter.convertImageMetadata(IIOMetadata inData,
ImageTypeSpecifier imageType,
ImageWriteParam param) |
abstract IIOMetadata |
ImageWriter.getDefaultImageMetadata(ImageTypeSpecifier imageType,
ImageWriteParam param)
Returns an
IIOMetadata object containing default
values for encoding an image of the given type. |
static Iterator<ImageWriter> |
ImageIO.getImageWriters(ImageTypeSpecifier type,
String formatName)
Returns an
Iterator containing all currently
registered ImageWriters that claim to be able to
encode images of the given layout (specified using an
ImageTypeSpecifier) in the given format. |
int |
ImageWriter.getNumThumbnailsSupported(ImageTypeSpecifier imageType,
ImageWriteParam param,
IIOMetadata streamMetadata,
IIOMetadata imageMetadata)
Returns the number of thumbnails supported by the format being
written, given the image type and any additional write
parameters and metadata objects that will be used during
encoding.
|
Dimension[] |
ImageWriter.getPreferredThumbnailSizes(ImageTypeSpecifier imageType,
ImageWriteParam param,
IIOMetadata streamMetadata,
IIOMetadata imageMetadata)
