示例1: draw
# 需要导入模块: from SimpleCV.ImageClass import Image [as 别名]
# 或者: from SimpleCV.ImageClass.Image import set_colorkey [as 别名]
def draw(self, color = Color.GREEN, width = -1, alpha = -1, layer = None):
"""
**SUMMARY**
Draw the blob, in the given color, to the appropriate layer
By default, this draws the entire blob filled in, with holes. If you
provide a width, an outline of the exterior and interior contours is drawn.
**PARAMETERS**
* *color* -The color to render the blob as a color tuple.
* *alpha* - The alpha value of the rendered blob 0=transparent 255=opaque.
* *width* - The width of the drawn blob in pixels, if -1 then filled then the polygon is filled.
* *layer* - A source layer, if layer is not None, the blob is rendered to the layer versus the source image.
**RETURNS**
This method either works on the original source image, or on the drawing layer provided.
The method does not modify object itself.
**EXAMPLE**
>>> img = Image("lenna")
>>> blobs = img.findBlobs()
>>> blobs[-2].draw(color=Color.PUCE,width=-1,alpha=128)
>>> img.show()
