Method Image.Image()->bitscale()

class Image.Image

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
