Predefinição:Superimpose

Documentação da predefinição[ver] [editar] [histórico] [purgar]

{{Superimpose}} 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.

Example

editar

{{Superimpose
  | base = US_Locator_Blank.svg
  | base_width = 288px
  | base_alt = Located in north central Colorado, which in turn 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

editar

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

editar

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 Wikipedia:Alternative text for images. This normally describes the combination of the two images.
base_caption: Text to show when a user's mouse hovers over the base image; ignored if base_link is specified to be empty
base_link: Name of page that the user should 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 top image
float_width: Width to display the top image, in pixels
float_alt: Alt text for the top 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 a user's mouse hovers over the top image; ignored if float_link is missing or empty
float_link: Name of page that the user should be sent to if they click on the top image. This acts like base_link, except it is for the top image, and it defaults to empty.
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

editar

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)
