Template:Superimpose
This template 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_caption = United States Locator Map
| float = Red Dot.svg
| float_width = 10px
| float_caption = Boulder, Colorado
| x = 83
| y = 53
}
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_caption =
| float =
| float_width =
| 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_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_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)
