Description
Implements a 'CAPTCHA' image.
Constructors
public
JOTCaptchaImage
(int width, int height)
public
JOTCaptchaImage
(int width, int height, int ALPHA_TYPE)
Methods
public void
drawFilledRectangle
(int x, int y, int x2, int y2, JOTAbstractPixel pixel)
[Inherited From JOTAbstractImage]
protected void
drawHorizontalLine
(int lineThickness, int x, int x2, int y, JOTAbstractPixel pixel)
[Inherited From JOTAbstractImage]
public void
drawLine
(int lineThickness, int x, int y, int x2, int y2, JOTAbstractPixel pixel)
[Inherited From JOTAbstractImage]
public void
drawRectangle
(int lineThickness, int x, int y, int x2, int y2, JOTAbstractPixel pixel)
[Inherited From JOTAbstractImage]
protected void
drawVerticalLine
(int lineThickness, int x, int y, int y2, JOTAbstractPixel pixel)
[Inherited From JOTAbstractImage]
protected void
drawWavyHorizontalLine
(int lineThickness, int x, int x2, int y, JOTAbstractPixel pixel, int wavyness, boolean holes)
public void
drawWavyLine
(int lineThickness, int x, int y, int x2, int y2, JOTAbstractPixel pixel, boolean holes)
Draw a wavy line with given thickness (uses wavyness)
If holes is enabled, some blank pixel with be mixed, leaving holes
public void
drawWavyLine
(int x, int y, int x2, int y2, JOTAbstractPixel pixel, boolean holes)
Draw a wavy line with a thickness of 1 pixel (uses wavyness)
protected void
drawWavyVerticalLine
(int lineThickness, int x, int y, int y2, JOTAbstractPixel pixel, int wavyness, boolean holes)
public void
fillImage
(JOTAbstractPixel pixel)
[Inherited From JOTAbstractImage]
fill the whole image with the same pixel
ie: set a background
public int
getColorDepth
(long maxColors)
throws
Exception
[Inherited From JOTAbstractImage]
return the color depth in bits (ie: how big the palette needs to be)
ie:
1: 2 colors or less
4: 16 colors or less
8: 256 colors or less
16: 65536 colors or less
24: 16 777 216 colors or less
32: > 16 777 216 colors
resource intensive
Note: maxColors, is the maximum you want to look for, if more that "maxColor" colors are found, an exception will be thrown.
public int
getWaviness
()
public void
setWaviness
(int waviness)
public int
writeToStream

Fields
publicfinalstatic
int ALPHA_SUPPORT_NONE
= "1"
[Inherited From JOTAbstractImage]

int ALPHA_SUPPORT_SIMPLE_BLEND
= "2"
[Inherited From JOTAbstractImage]
If a pixel is set a new color, we will mix the new color with the old one.
