Template:Superimpose/doc

{{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
{{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 Dot.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 impaired readers; see WP:ALT. This should describe the combination of the two images.
- base_caption: Text to show when the mouse courser user 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 image to be superimposed.
- 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 user 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-standard 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-standard units
