```go-html-template ```go-html-template
{{ $font := "" }} {{ $font := "" }}
{{ $path := "https://github.com/google/fonts/raw/main/ofl/lato/Lato-Regular.ttf" }} {{ with try (resources.GetRemote $fontPath) }}
{{ with try (resources.GetRemote $path) }}
{{ with .Err }} {{ with .Err }}
{{ errorf "%s" . }} {{ errorf "%s" . }}
{{ else with .Value }} {{ else with .Value }}
{{ $font = . }} {{ $font = . }}
{{ else }} {{ else }}
{{ errorf "Unable to get resource %q" $path }} {{ errorf "Unable to get resource %s" $fontPath }}
{{ end }} {{ end }}
{{ end }} {{ end }}
``` ```
Create the options map: Create the filter, centering the text horizontally and vertically:
```go-html-template ```go-html-template
{{ $opts := dict {{ $r := "" }}
{{ $filter := "" }}
{{ with $r = resources.Get $imagePath }}
{{ $opts := dict
"alignx" "center"
"color" "#fbfaf5" "color" "#fbfaf5"
"font" $font "font" $font
"linespacing" 8 "linespacing" 8
"size" 40 "size" 60
"x" 25 "x" (mul .Width 0.5 | int)
"y" 190 "y" (mul .Height 0.5 | int)
}} }}
{{ $filter = images.Text $text $opts }}
{{ else }}
{{ errorf "Unable to get resource %s" $imagePath }}
{{ end }}
``` ```
Set the text: Apply the filter using the [`images.Filter`] function:
```go-html-template ```go-html-template
{{ $text := "Zion National Park" }} {{ with $r }}
{{ with . | images.Filter $filter }}
<img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
{{ end }}
{{ end }}
``` ```
Create the filter: You can also apply the filter using the [`Filter`] method on a `Resource` object:
```go-html-template ```go-html-template
{{ $filter := images.Text $text $opts }} {{ with $r }}
{{ with .Filter $filter }}
<img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
{{ end }}
{{ end }}
``` ```
