Method Image.Image()->bitscale()

Method bitscale

object bitscale(float factor)
object bitscale(float xfactor, float yfactor)

Description

scales the image with a factor, without smoothing. This routine is faster than scale, but gives less correct results


original	bitscale(0.75)	scale(0.75)

Parameter factor

factor to use for both x and y

Parameter xfactor

Parameter yfactor

separate factors for x and y

Returns

the new image object

Method bitscale: object bitscale(int newxsize, int newysize)
object bitscale(0, int newysize)
object bitscale(int newxsize, 0)
Description: scales the image to a specified new size, if one of newxsize or newysize is 0, the image aspect ratio is preserved.
Parameter newxsize
Parameter newysize: new image size in pixels
Returns: the new image object
Note: resulting image will be 1x1 pixels, at least
