示例1: image
# 需要导入模块: from java.awt.image import BufferedImage [as 别名]
# 或者: from java.awt.image.BufferedImage import getRaster [as 别名]
def image(self):
w = self.getWidth();
h = self.getHeight();
non_black_withe_image = BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB)
self.paint(non_black_withe_image.getGraphics())
raster=non_black_withe_image.getRaster()
bi = BufferedImage(w, h, BufferedImage.TYPE_BYTE_BINARY)
write_raster = bi.getRaster()
c = array.zeros('i', 4)
on=wc = array.zeros('i', 1)
off=array.zeros('i', 1)
off[0]=1
for x in range(w):
for y in range(h):
c = raster.getPixel(x,y,c)
if sum(c)!=1020:
write_raster.setPixel(x,y, on)
else:
write_raster.setPixel(x,y, off)
