{{Superimpose/doc}} is a utility which superimposes one image over another, and positions it relative to the top left corner of the bottom image. Although the original idea was to place a dot on a locator map based on editable coordinates, it can be used to precisely overlay any two images for any reason.
Usage
Example
The wikicode below will create the image at right:
{{Superimpose | base = US_Locator_Blank.svg | base_width = 288px | base_alt = U.S. map with state boundaries | base_caption = United States Locator Map | float = Red Dot.svg | float_width = 10px | float_alt = Boulder is in north central Colorado. | float_caption = Boulder, Colorado | x = 95 | y = 80 }}
Using the Template
To get started, you can simply copy this blank definition into your page, and fill in the data.
{{Superimpose| base = | base_width = | base_alt = | base_caption = | float = | float_width = | float_alt = | float_caption = | x = | y = }}
Parameter Definitions
- base: File name of the base (bottom) image
- base_width: Width to display the base image, in pixels
- base_alt: Alt text for the image, for visually impaired readers; see WP:ALT
- base_caption: Text to show when a user's mouse hovers over the base image
- float: File name of the top image
- float_width: Width to display the top image, in pixels
- float_alt: Alt text for the top image
- float_caption: Text to show when a user's mouse hovers over the top image
- x: distance to offset the top image from the left edge of the base image, in pixels or any other CSS-standard units
- y: distance to offset the top image from the top edge of the base image, in pixels or any other CSS-standard units
A Note about the Locator Dot
I originally built this template thinking I could use an SVG file with transparency (mostly for the dot in locator maps). However, it seems Internet Explorer users can't handle transparent PNGs without a fix that Wikimedia's not yet delivering, so for now I recommend using the GIF version in the example above. When IE better supports PNGs, we can swap the better format back in. —Papayoung ☯ 02:06, 26 October 2005 (UTC)
