| FileImageReader | | abstract public class FileImageReader extends StreamImageReader (Code) | | Base class for image readers that require
File input source. If the input source
is of other kind, then the content will be copied to a temporary file. This class is used
for image formats backed by some external API (typically C/C++ libraries) working only with
files.

| FileImageReader | | public FileImageReader(ImageReaderSpi spi)(Code) | | Constructs a new image reader.
Parameters:
provider - The ImageReaderSpi that is invoking this constructor,or null if none. |
| close | | protected void close() throws IOException(Code) | | Deletes the temporary file, if any.
|
| getInputFile | | protected File getInputFile() throws IOException(Code) | | Returns the
as a file. If the input is not a file,
then its content is copied to a temporary file and the temporary file is returned.
The as a file.
throws:
FileNotFoundException - if the file is not found or can not be read.
throws:
IOException - if a copy was necessary but failed. |
| getURLEncoding | | public String getURLEncoding()(Code) | | Returns the encoding used for
.
The default implementation returns
"UTF-8" in all cases. Subclasses
should override this method if
FileImageReader.getInputFile should converts
URL to
File objects using a different encoding.
|
| isRandomAccessEasy | | public boolean isRandomAccessEasy(int imageIndex) throws IOException(Code) | | Returns
true since image readers backed by
File object usually supports random access efficiently.
