images.Text TEXT [OPTIONS]

Options

Although none of the options are required, at a minimum you will want to set the size to be some reasonable percentage of the image height.

alignx
{{< new-in 0.141.0 />}}
(string) The horizontal alignment of the text relative to the horizontal offset, one of left, center, or right. Default is left.
color
(string) The font color, either a 3-digit or 6-digit hexadecimal color code. Default is #ffffff (white).
font
(resource.Resource) The font can be a global resource, a page resource, or a remote resource. Default is Go Regular, a proportional sans-serif TrueType font.
linespacing
(int) The number of pixels between each line. For a line height of 1.4, set the linespacing to 0.4 multiplied by the size. Default is 2.
size
(int) The font size in pixels. Default is 20.
x
(int) The horizontal offset, in pixels, relative to the left of the image. Default is 10.
y
(int) The vertical offset, in pixels, relative to the top of the image. Default is 10.

Usage

Set the text and paths:

{{ $text := "Zion National Park" }}
{{ $fontPath := "https://github.com/google/fonts/raw/main/ofl/lato/Lato-Regular.ttf" }}
{{ $imagePath := "images/original.jpg" }}

Capture the font as a resource:

{{ $font := "" }}
{{ with try (resources.GetRemote $fontPath) }}
  {{ with .Err }}
    {{ errorf "%s" . }}
  {{ else with .Value }}
    {{ $font = . }}
  {{ else }}
    {{ errorf "Unable to get resource %s" $fontPath }}
  {{ end }}
{{ end }}

Create the filter, centering the text horizontally and vertically:

{{ $r := "" }}
{{ $filter := "" }}
{{ with $r = resources.Get $imagePath }}
  {{ $opts := dict
    "alignx" "center"
    "color" "#fbfaf5"
    "font" $font
    "linespacing" 8
    "size" 60
    "x" (mul .Width 0.5 | int)
    "y" (mul .Height 0.5 | int)
  }}
  {{ $filter = images.Text $text $opts }}
{{ else }}
  {{ errorf "Unable to get resource %s" $imagePath }}
{{ end }}

Apply the filter using the images.Filter function:

{{ with $r }}
  {{ with . | images.Filter $filter }}
    <img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
  {{ end }}
{{ end }}

You can also apply the filter using the Filter method on a Resource object:

{{ with $r }}
  {{ with .Filter $filter }}
    <img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
  {{ end }}
{{ end }}

Example

{{< img src="images/examples/zion-national-park.jpg" alt="Zion National Park" filter="Text" filterArgs="Zion National Park,25,190,40,1.2,#fbfaf5" example=true

}}
