## Usage
Set the text and paths:
```go-html-template
{{ $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:
```go-html-template
{{ $font := "" }}
{{ $path := "https://github.com/google/fonts/raw/main/ofl/lato/Lato-Regular.ttf" }}
{{ with try (resources.GetRemote $path) }}
{{ with try (resources.GetRemote $fontPath) }}
{{ with .Err }}
{{ errorf "%s" . }}
{{ else with .Value }}
{{ $font = . }}
{{ else }}
{{ errorf "Unable to get resource %q" $path }}
{{ errorf "Unable to get resource %s" $fontPath }}
{{ end }}
{{ end }}
```
Create the options map:
Create the filter, centering the text horizontally and vertically:
```go-html-template
{{ $opts := dict
"color" "#fbfaf5"
"font" $font
"linespacing" 8
"size" 40
"x" 25
"y" 190
}}
{{ $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 }}
```
Set the text:
Apply the filter using the [`images.Filter`] function:
```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
{{ $filter := images.Text $text $opts }}
{{ with $r }}
{{ with .Filter $filter }}
<img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
{{ end }}
{{ end }}
```
