Method Details

getSaveableImageFileFormats

public static String[] getSaveableImageFileFormats()

Returns:

ImageIO.getWriterFileSuffixes()

Since:

1.0

isFormatRGBOnly

public static boolean isFormatRGBOnly(String imgFormat)

returns if specified image format supports rgb values only. This means argb values probably need conversion beforehand.

Parameters:

imgFormat - the file format e.g. jpg or png

Returns:

true if format only supports rgb values

Since:

1.0

isFormatBWOnly

public static boolean isFormatBWOnly(String imgFormat)

saveImage

public static void saveImage(Image image,
 OutputStream os,
 String imgFileFormat)

Saves specified Image to file of specified img file format.

Some image file formats may require image type conversion before saving. This method converts to type INT_RGB for jpg, jpeg and bmp, and to type BYTE_BINARY for wbmp.

The provided OutputStream will not be closed, this is the responsibility of the caller.

Parameters:

image - to be saved

os - OutputStream to write image to.

imgFileFormat - image file format. Consult getSaveableImageFileFormats() to get the supported img file formats of your system.

Throws:

ContourPlot.ImageSaver.ImageSaverException - if an IOException occurred during the process or no appropriate writer could be found for specified format.

Since:

1.1

isBufferedImageOfType

private static final boolean isBufferedImageOfType(Image image,
 int type)

saveImage

public static void saveImage(Image image,
 String filename,
 String imgFileFormat)

Saves image using saveImage(Image, File, String).

Parameters:

image - to be saved

filename - path to file

imgFileFormat - image file format. Consult getSaveableImageFileFormats()

Throws:

ContourPlot.ImageSaver.ImageSaverException - if an IOException occurred during the process, the provided filename path does refer to a directory or no appropriate writer could be found for specified format.

Since:

1.0

saveImage

public static void saveImage(Image image,
 File file,
 String imgFileFormat)

Saves image using saveImage(Image, OutputStream, String).

Parameters:

image - to be saved

file - to save image to

imgFileFormat - image file format. Consult getSaveableImageFileFormats()

Throws:

ContourPlot.ImageSaver.ImageSaverException - if an IOException occurred during the process, no OutputStream could be created due to a FileNotFoundException or no appropriate writer could be found for specified format.

Since:
