ImageWriteParam param) |
IIOMetadata |
ImageTranscoder.convertStreamMetadata(IIOMetadata inData,
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.convertStreamMetadata(IIOMetadata inData,
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. |
abstract IIOMetadata |
ImageWriter.getDefaultStreamMetadata(ImageWriteParam param)
Returns an
IIOMetadata object containing default
values for encoding a stream of images. |
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)
Returns an array of
Dimensions indicating the
legal size ranges for thumbnail images as they will be encoded
in the output file or stream. |
void |
ImageWriter.prepareInsertEmpty(int imageIndex,
ImageTypeSpecifier imageType,
int width,
int height,
IIOMetadata imageMetadata,
List<? extends BufferedImage> thumbnails,
ImageWriteParam param)
Begins the insertion of a new image with undefined pixel values
into an existing image stream.
|
void |
ImageWriter.prepareWriteEmpty(IIOMetadata streamMetadata,
ImageTypeSpecifier imageType,
int width,
int height,
IIOMetadata imageMetadata,
List<? extends BufferedImage> thumbnails,
ImageWriteParam param)
Begins the writing of a complete image stream, consisting of a
single image with undefined pixel values and associated
metadata and thumbnails, to the output.
|
void |
ImageWriter.replacePixels(Raster raster,
ImageWriteParam param)
Replaces a portion of an image already present in the output
with a portion of the given
Raster. |
void |
ImageWriter.replacePixels(RenderedImage image,
ImageWriteParam param)
Replaces a portion of an image already present in the output
with a portion of the given image.
|
abstract void |
ImageWriter.write(IIOMetadata streamMetadata,
IIOImage image,
ImageWriteParam param)
Appends a complete image stream containing a single image and
associated stream and image metadata and thumbnails to the
output.
|
void |
ImageWriter.writeInsert(int imageIndex,
IIOImage image,
ImageWriteParam param)
Inserts a new image into an existing image stream.
|
void |
ImageWriter.writeToSequence(IIOImage image,
ImageWriteParam param)
Appends a single image and possibly associated metadata and
thumbnails, to the output.
|
| Modifier and Type | Class and Description |
|---|---|
class |
BMPImageWriteParam
A subclass of
ImageWriteParam for encoding images in
the BMP format. |
| Modifier and Type | Class and Description |
|---|---|
class |
JPEGImageWriteParam
This class adds the ability to set JPEG quantization and Huffman
tables when using the built-in JPEG writer plug-in, and to request that
optimized Huffman tables be computed for an image.
