সাঁচ:Location mark/doc

This template places a mark on an image, with an optional label. I is a simplified version of {{Location mark+}}.

Other templates are more capable of superimposing one image on another. This template centers a mark over a location on any image using coordinate values that are relative. The size of the composite image can changed without changing the relative positions of the markers. The composite image can be displayed as a simple image, a bordered image or a thumbnail image.

If the geographic coordinates of the location are known and a location map template exists then one of the templates in the Location map family should be used. The See also section below lists alternative templates.

Usage

Four Corners

A location in the U.S.

{{Location mark | image = | overlay = | width = | caption = | alt = | float = | type = | label = | position = | font_size = | background = | mark = | mark_width = | mark_alt = | mark_link = | x = | y = }}

Parameters

Parameters for Location map+

Parameter	Description
image	Required. The name of an image file.
overlay	The name of an image file to superimpose on the image. It should be the same size and have a transparent background.
width	Determines the width of the image in pixels. The default is 220px. For example width=240 and not width=240px.
caption	The caption text displays below the image if the thumbnail option is used. See the examples.
alt	Alt text for the map. See WP:ALT. If no alt text is provided the caption text will be used.
type	Determines the display format. Valid values are thumb, and border. The thumb option generates output similar to [[File:|name|thumb]], while the border option generates output similar to [[File:|name|border]]. If no valid value is assigned, the output will not be framed or bordered. See below and this page.
float	Determines the position of the image on the page. Valid values are left, right, center and none. The default is right.
label	Optional. The text of the label to display next to the mark. The text can be wiki linked.
position	The position of the label relative to the mark. Valid values are left, right, top and bottom. The default is right. If none is assigned then the template will place the label either to the right or the left depending on the location of the mark.
font_size	The font size to use for the label as a percentage. The default is 90%. For example font_size=80.
background	The background color to use for the label text. See Web colors. By default the background color is inherited from the image behind the label.
mark	The name of an image to display as the mark. The default is Red pog.svg. Go here and here for some examples.
mark_width	The width of the mark in pixels. The default is 8px. For example mark_width=7 and not mark_width=7px. Labels do not work well with large mark images. This template is not intended to generate overlays. See {{Superimpose}}.
mark_link	Specifies a wiki link which will be followed if the reader clicks on the mark. The name of the linked article will be displayed as a tool tip when the mouse pointer hovers over the mark.
mark_alt	Alt text for the mark image. See WP:ALT. If no mark_alt text is provided the label text will be used.
x	Determines the location of the mark in the horizontal axis. See below.
y	Determines the location of the mark in the vertical axis. See below.

The x and y parameters

The values for the x and y parameters are the pixel coordinates of the location mark when the image is scaled to a width of 1000 pixels.

x is the pixel offset for the mark from the left edge of an image 1000px wide.

y is the pixel offset for the mark from the top edge of an image 1000px wide.

There are at least two ways of obtaining these values:

1. Download the image from the image's file page to your computer. Open the image in a graphics editor, such as GIMP or XnView. Scale (resize) the image to a width of 1000px and then note the x, y coordinates when the mouse cursor points to to the desired location. Use these values directly.
2. Download the image from the image's file page to your computer. Open the image in any image viewer that displays the coordinates of the cursor position, such as Paint from Microsoft. Note the X, Y coordinates when the mouse cursor points to the location. Then:

1000 · x'/w = x  and  1000 · y'/w = y

where x' and y' are the mouse cursor coordinates, w is the width of the image displayed on your computer and x and y are the values to assign to the x and y parameters.

These computed coordinates are relative and will work even if the width of the image displayed in an article is changed by another user. Using simple pixel coordinate values would not have this advantage. Note that Wikipedia does not allow the aspect ratio of an image to be altered.

The type parameter

type=	type=border	type=thumb
Rattray Head	Rattray Head	Rattray Head Rattray Head in Scotland

Examples

The first two examples could be duplicated using {{Location map+}}.

Using mostly default values

Cape Wrath

{{Location mark
| width = 
| image = Scotland relief location map.jpg
| caption = Scotland
| float = 
| type = 
| width = 
| label = '''Cape Wrath'''
| position = 
| x = 452 | y = 480
}}

Using background color for labels

Düsseldorf

Location of Düsseldorf in North Rhine-Westphalia

{{Location mark
| image = North Rhine-Westphalia location map 05.svg
| width = 300
| caption = Location of Düsseldorf in [[North Rhine-Westphalia]]
| type = thumb
| width = 300
| label = Düsseldorf
| position = left
| background = #a7cb9d
| x = 267 | y = 574
}}

Using an invisible mark

Rachel

A cute chick

{{Location mark
| image = Take five.jpg
| caption = A cute chick
| type = thumb
| label = Rachel
| position = top
| background = #ae9074
| mark = Blanksvg.svg
| x = 433 | y = 295
}}
