View width. Specifies the width of the response image (view image) when fit= is not present in the request.
wid= *
val*
val | Image width in pixels (int greater than 0). |
If both hei=
and scl=
are specified, the composite image may be cropped according to the align=
attribute. When fit=
is present, wid=
specifies the exact, the minimum, or the maximum response image width; refer to the description of fit=
for details.
If scl=
is not specified, the composite image is scaled to fit. If both wid=
and hei=
are specified, and scl=
is not specified, then the image is scaled to fit entirely within the wid/hei rectangle, leaving as little background area exposed as possible. In this case, the image is positioned within the view rectangle according to the align=
attribute.
attribute::MaxPix
.Default
If neither wid=
, hei=
, nor scl=
are specified, the reply image either has the size of the composite image or attribute::DefaultPix
, whichever is smaller.
Properties
View attribute. It applies regardless of the current layer setting.
Example
Request an image so it can fit into a 200x200 rectangle; top-right align the image if it is not square. Any background area is filled with attribute::BkgColor
.
http:// *
Server*/myRootId/myImageId?wid=200&hei=200&align=1,-1
The same image, delivered at a fixed width of 200 pixels, but with a variable height to maintain the aspect ratio of the image. In this case, the returned image never has any background fill areas. In this case, align=
would have no effect at all.
