UnsupportedEncodingException
- on error
-
generate
public int generate(byte[] text, int textOffset, int textSize) Creates a barcode.- Parameters:
text
- the texttextOffset
- the offset to the start of the texttextSize
- the text size- Returns:
- the status of the generation. It can be one of this values:
DM_NO_ERROR
- no error.
DM_ERROR_TEXT_TOO_BIG

-
createImage
Gets anImage
with the barcode. A successful call to the methodgenerate()
before calling this method is required.- Returns:
- the barcode
Image
- Throws:
BadElementException
- on error
-
createAwtImage
Creates ajava.awt.Image
. A successful call to the methodgenerate()
before calling this method is required.- Parameters:
foreground
- the color of the barsbackground
- the color of the background- Returns:
- the image
-
getImage
public byte[] getImage()Gets the generated image. The image is represented as a stream of bytes, each byte representing 8 pixels, 0 for white and 1 for black, with the high-order bit of each byte first. Each row is aligned at byte boundaries. The dimensions of the image are defined by height and width plus 2 * ws.- Returns:

public int getWs()Gets the whitespace border around the barcode.- Returns:
- the whitespace border around the barcode
-
setWs
public void setWs(int ws) Sets the whitespace border around the barcode.- Parameters:
ws
- the whitespace border around the barcode
