public final class ImageUtil extends Object
Modifier and Type | Method and Description |
---|---|
static InputStream |
autoDecorateInputStream(InputStream in)
Automatically decorates an InputStream so it is buffered.
|
static void |
closeQuietly(Source src)
Deprecated.
use
XmlSourceUtil.closeQuietly(Source) instead |
static InputStream |
decorateMarkSupported(InputStream in)
Decorates an InputStream with a BufferedInputStream if it doesn't support mark()/reset().
|
static Map |
getDefaultHints(ImageSessionContext session)
Creates a new hint Map with values from the FOUserAgent.
|
static ImageInputStream |
getImageInputStream(Source src)
Returns the ImageInputStream of a Source object.
|
static InputStream |
getInputStream(Source src)
Deprecated.
Please use
XmlSourceUtil.getInputStream(Source) instead. |
static Integer |
getPageIndexFromURI(String uri)
Extracts page index information from a URI.
|
static boolean |
hasImageInputStream(Source src)
Indicates whether the Source object has an ImageInputStream instance.
|
static boolean |
hasInputStream(Source src)
Indicates whether the Source object has an InputStream instance.
|
static boolean |
hasReader(Source src)
Deprecated.
use
XmlSourceUtil.hasReader(Source) instead |
static ImageInputStream |
ignoreFlushing(ImageInputStream in)
Decorates an ImageInputStream so the flush*() methods are ignored and have no effect.
|
static boolean |
isGZIPCompressed(InputStream in)
Indicates whether an InputStream is GZIP compressed.
|
static ImageInputStream |
needImageInputStream(Source src)
Returns the ImageInputStream of a Source object.
|
static InputStream |
needInputStream(Source src)
Deprecated.
use
XmlSourceUtil.needInputStream(Source) instead |
static int |
needPageIndexFromURI(String uri)
Extracts page index information from a URI.
|

3.)
If no page index information is found in the URI or if the URI cannot be parsed, the method returns null.
