Reply image width. Specifies scaling of the rendered image so that the reply image is no taller than the specified value, while maintaining the image's aspect ratio.
wid= * val *
Image width in pixels (int greater than 0).
The image is not padded if both wid= and hei= is specified and wid / hei is different than the aspect ratio of the image.
wid= and hei= work together to define the size of the image that is returned by the server. 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. Resizing the image with wid= , hei= , or scl= does not change the print resolution value embedded in the response image. Ignored if scl= occurs after wid= or hei= in the command sequence.
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 will have the same size as the vignette's view image.
