Constructor Details

Picture

public Picture(InputStream is)
        throws IOException

Creates a new Picture object, reading the InputStream passed as parameter to obtain a BufferedImage

Parameters:

is - The InputStream to read

Throws:

IOException - If an error occur during reading an exception is raised

Picture

public Picture(byte[] bb)
        throws IOException

Creates a new Picture object starting from the byte array passed as parameter to obtain a BufferedImage

Parameters:

bb - The byte array to read

Throws:

IOException - If an error occur during reading, an exception is raised

Picture

public Picture(BufferedImage bi)

Creates a new Picture object starting from the BufferedImage passed as parameter

Parameters:

bi - The BufferedImage used to create the object

Method Details

setFormat

public void setFormat(String format,
 float quality)

Sets the format of the Picture object

Parameters:

format - Can be "png" that is the default value, or "jpg"

quality - The compression quality, a float value between 0 and 1; if the format is "png" the quality is lossless

getFormat

public String getFormat()

Returns the format of the Picture object (see setFormat(java.lang.String, float))

Returns:

The string that defines the format of the Picture object

getBufferedImage

public BufferedImage getBufferedImage()

Returns the BufferedImage created constructing the Picture object

Returns:

The BufferedImage

getWidth

public int getWidth()

Returns the width of the BufferedImage created constructing the Picture object

Returns:

The int value that defines the width of the Picture

getHeight

public int getHeight()

Returns the height of the BufferedImage created constructing the Picture object

Returns:

The int value that defines the height of the Picture

cropAndScale

public void cropAndScale(Color bkg,
 int x1,
 int y1,
 int x2,
 int y2,
 int w,
 int h)
                  throws IOException

Makes the crop and scale transformations on the image

Parameters:

bkg - The background color to use in the tool

x1 - The first x coordinate for the crop

y1 - The second x coordinate for the crop

x2 - The first y coordinate for the crop

y2 - The second y coordinate for the crop

w - The width for the scaling

h - The height for the scaling

Throws:

IOException - If an error occur during the transformations, an exception is raised
