<cimg-url/>

Provided by module: Image converter

This tag generates an URI to the manipulated picture. <cimg-url> takes the same attributes as <cimg>, including the image cache attributes. The use for the tag is to insert image-URI's into various places, e.g. a submit-box.

Attributes

Default for gif is 32(+1 transparent), for most other formats (except black and white) is it unlimited.

<cimg-url src='/internal-roxen-testimage' quant='2'/> /_internal/cimg!0/31e.png

dither="{none, random, floyd-steinberg}" (none)

Choose the dithering method.

Method	Meaning
none	No dithering is performed at all.
random	Random scatter dither. Not visually pleasing, but it is useful for very high resolution printing.
floyd-steinberg	Error diffusion dithering. Usually the best dithering method.

<cimg-url src='/internal-roxen-testimage' dither='random' quant='10'/> /_internal/cimg!0/eef.png

true-alpha

If present, render a real alpha channel instead of on/off alpha. If the file format only supports on/off alpha, the alpha channel is dithered using a floyd-steinberg dither.
