createGraphics(BufferedImage image,
Color color)
|
static Graphics |
drawImg(Graphics g,
Image img,
Point point)
绘制图片
|
static Graphics |
drawImg(Graphics g,
Image img,
Rectangle rectangle)
绘制图片
|
static Graphics |
drawString(Graphics g,
String str,
Font font,
Color color,
int width,
int height)
绘制字符串，默认抗锯齿
|

绘制字符串，默认抗锯齿
|
static Graphics |
drawString(Graphics g,
String str,
Font font,
Color color,
Point point)
绘制字符串，默认抗锯齿
|
static Graphics |
drawString(Graphics g,
String str,
Font font,
Color color,
Rectangle rectangle)
绘制字符串，默认抗锯齿。

static Graphics |
drawStringColourful(Graphics g,
String str,
Font font,
int width,
int height)
绘制字符串，使用随机颜色，默认抗锯齿
|
static Graphics |
drawStringColourful(Graphics g,
String str,
Font font,
int width,
int height,
Color backgroundColor)

|
static Graphics |
drawStringColourful(Graphics g,
String str,
Font font,
int width,
int height,
Color compareColor,
int minColorDistance)
绘制字符串，使用随机颜色，默认抗锯齿
|
static int |
getCenterY(Graphics g,

setAlpha(Graphics2D g,
float alpha)
设置画笔透明度
