{{Superimpose}} is a utility template which superimposes one image on top another. The position of the superimposed image is relative to the top left corner of the underlying image. It is often used to display a location mark on a map image, but it can be used with any two images.

Usage

Example

{{Superimpose
  | base = US_Locator_Blank.svg
  | base_width = 288px
  | base_alt = Located in north central Colorado, which is just west of the center of the U.S.
  | base_caption = United States Locator Map
  | float = Red pog.svg
  | float_width = 10px
  | 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 = 
  | x = 
  | y = 
}}

The following blank definition includes all the parameters, including those less-commonly used.

{{Superimpose
  | base = 
  | base_width = 
  | base_alt = 
  | base_caption = 
  | base_link = 
  | float = 
  | float_alt = 
  | float_width = 
  | float_caption = 
  | float_link = 
  | x = 
  | y = 
}}

Parameter Definitions

base: File name of the base (underlying) image.
base_width: Width to display the base image, in pixels.
base_alt: Alt text for the image, for visually users; see WP:ALT. This should describe the composite image.
base_caption: Text to show when the mouse courser hovers over the base image; ignored if base_link is specified to be empty.
base_link: Name of page that the user will be sent to if they click on the base image. The special value "file:", stands for the file page for the base image. If empty, nothing happens if the user clicks on the base image. The default is "file:".
float: File name of the superimposed image.
float_width: Width to display the superimposed image, in pixels.
float_alt: Alt text for the superimposed image. This is needed only if float_link is nonempty. Normally the alt text for the base image describes the combination of the two images, and this parameter is not needed.
float_caption: Text to show when the mouse courser hovers over the superimposed image; ignored if float_link is missing or empty
float_link: Name of page that the user will be sent to if they click on the superimposed image. This acts like base_link, except it is for the top image, and it defaults to empty.
x: distance to offset the left edge of the superimposed image from the left edge of the base image, in pixels or any other CSS units.
y: distance to offset the top edge of the superimposed image from the top edge of the base image, in pixels or any other CSS units.

-{{tl|{{PAGENAME}}}} is a utility which superimposes one image over another, and positions it relative to the top left corner of the bottom image. Although [[w:Template:GBthumb|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.

-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.
