public final class ImageUtil
Helper and convenience methods for working with the image package.
Method Summary | |
---|---|
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. |
static void |
removeStreams(Source src)
Deprecated. use XmlSourceUtil.removeStreams(Source) instead |

public static Integer getPageIndexFromURI(String uri)
http://www.foo.bar/images/scan1.tif#page=4
(The method will return
3.)
If no page index information is found in the URI or if the URI cannot be parsed, the method returns null.

- the URI that should be inspected
public static int needPageIndexFromURI(String uri)
http://www.foo.bar/images/scan1.tif#page=4
(The method will return
3.)
If no page index information is found in the URI, the method just returns 0 which indicates the first page.
