Scale view. Scales the rendered image by the specified scale factor, relative to the full-resolution vignette.
scl= * invFactor *
Inverse scale factor (real, 1.0 or greater).
If scl= comes after wid= or hei= in the URL, it cancels those commands and scl= defines the size of the image returned by the server.
However, if wid= or hei= comes after scl= in the URL, they cancel scl= and wid= / hei= define the size of the image returned by the server.
An error is returned if the calculated or default reply image size is larger than attribute::MaxPix .


May occur anywhere within the request. Ignored if wid= or hei= occur after scl= in the command sequence.
Resizing the image with scl= does not change the print resolution value embedded in the response image.


If neither wid= , hei= nor scl= are specified, the reply image is scaled to fit within the size defined by attribute::DefaultPix . If attribute::DefaultPix is empty, the reply image has the same size as the vignette's view image.
