Method Detail

resize

public static void resize(File sourceFile,
                          File targetFile,
                          String format,
                          int newWidth,
                          int newHeight)
                   throws IOException

Resizes the specified image file to the new width and height and writes it to the targetFile (creating the targetFile if it does not already exist).

The format string is the output format of the file, like "jpg", "gif" etc. This can be different than the format of the source file. The understood formats are those understood javax.io.ImageWriter (the usual suspects like gif, jpg, png, etc, all seem to work).

Throws:

IOException

resize

public static void resize(File sourceFile,
                          File targetFile,
                          int newWidth,
                          int newHeight)
                   throws IOException

Resizes the specified image file to the new width and height and writes it to the targetFile (creating the targetFile if it does not already exist).

The output format is the same as the input format and is intuited from the file name extension of the specified source file (therefore, source files specified to this method, should be like foo.gif, foo.jpg, etc).

Throws:

IOException

resize

public static BufferedImage resize(File sourceFile,
                                   int newWidth,
                                   int newHeight)
                            throws IOException

Resizes the specified image file to the new width and height and returns the new image.

Throws:

IOException
