Method Detail

initialize

void initialize(int maxWidth,
              int maxHeight,
              OrientationType orientation,
              PrintType printType,
              Integer fillColor)

Initializes the drawing surface

• if the specified maxWidth or maxHeight is 0 then the maximum values for the specified printer model will be used

Parameters:

maxWidth - the maximum width of the image (limited based on printer model).

maxHeight - the maximum height of the image (limited based on printer model).

orientation - the orientation of the image.

printType - the type of print to be performed.

fillColor - the RGB background fill color.

drawImage

void drawImage(byte[] imageData,
             int x,
             int y,
             int width,
             int height,
             RotationType rotation)
               throws IOException,
                      IllegalArgumentException

Draws the image into the specified rectangle

Parameters:

imageData - the bitmap image data

x - the x coordinate.

y - the y coordinate.

width - the width of the rectangle.

• if 0 then the width of the specified image will be used

height - the height of the rectangle.

• if 0 then the height of the specified image will be used

rotation - the rotation of the image.

Throws:

IOException - if an error occurs during reading/writing.

IllegalArgumentException - if an argument passed in is not valid.

createImage
