PngVCGenerator

public PngVCGenerator()

PngVCGenerator

public PngVCGenerator(int width,
              int height)

PngVCGenerator

public PngVCGenerator(int width,
              int height,
              int len)

PngVCGenerator

public PngVCGenerator(int width,
              int height,
              int len,
              Font font)

PngVCGenerator

public PngVCGenerator(int width,
              int height,
              int len,
              Font font,
              float pbkAlpha,
              float pFontAlpha,
              float pOvalSize,

this constructor is different from others. parameters with prefix 'p' are static field. be care for the side effect to other beans

参数:

width - image width

height - image height

len - validation code length

font - font features

pbkAlpha - alpha channel for image background. default 7f

pFontAlpha - alpha channel for validation code font. default 7f

pOvalSize - the interference oval strike size. default 4

pOvalCount - the interference oval count. default 20
