Uses of ImageReadParam in javax.imageio |
---|
Modifier and Type | Method and Description |
---|---|
ImageReadParam |
ImageReader.getDefaultReadParam()
Returns a default ImageReadParam object
appropriate for this format. |
Modifier and Type | Method and Description |
---|---|
protected static void |
ImageReader.checkReadParamBandSettings(ImageReadParam param,
int numSrcBands,
int numDstBands)
A utility method that may be used by readers to test the validity of the source and destination band settings of an ImageReadParam . |
protected static void |
ImageReader.computeRegions(ImageReadParam param,
int srcWidth,
int srcHeight,
BufferedImage image,
Rectangle srcRegion,
Rectangle destRegion)
Computes the source region of interest and the destination region of interest, taking the width and height of the source image, an optional destination image, and an optional ImageReadParam into account. |
protected static BufferedImage |
ImageReader.getDestination(ImageReadParam param,
Iterator<ImageTypeSpecifier> imageTypes,
int width,
int height)
Returns the BufferedImage to which decoded pixel
data should be written. |
protected static Rectangle |
ImageReader.getSourceRegion(ImageReadParam param,
int srcWidth,
int srcHeight)
A utility method that may be used by readers to compute the region of the source image that should be read, taking into account any source region and subsampling offset settings in the supplied ImageReadParam . |
abstract BufferedImage |
ImageReader.read(int imageIndex,
ImageReadParam param)
Reads the image indexed by imageIndex and returns
it as a complete BufferedImage , using a supplied
ImageReadParam . |
IIOImage |
ImageReader.readAll(int imageIndex,
ImageReadParam param)
Reads the image indexed by imageIndex and returns
an IIOImage containing the image, thumbnails, and
associated image metadata, using a supplied
ImageReadParam . |
RenderedImage |
ImageReader.readAsRenderedImage(int imageIndex,
ImageReadParam param)
Returns a RenderedImage object that contains the
contents of the image indexed by imageIndex . |
Raster |
ImageReader.readRaster(int imageIndex,
ImageReadParam param)
Returns a new Raster object containing the raw pixel data
from the image stream, without any color conversion applied. |
Modifier and Type | Method and Description |
---|---|
Iterator<IIOImage> |
ImageReader.readAll(Iterator<? extends ImageReadParam> params)
Returns an Iterator containing all the images,
thumbnails, and metadata, starting at the index given by
getMinIndex , from the input source in the form of
IIOImage objects. |
