### Harfbuzz hb-view and hb-shape
|
||
|
|
These are part of the HarfBuzz distribution and can help isolate if an issue is in the app/OS, shaping engine, or font.
|
||
|
|
* hb-view renders the text with the exact font (for example, to see how ligatured characters shape) using your installed version of HarfBuzz.
|
||
|
|
|
||
|
|
For example:
|
||
|
|
```
|
||
|
|
hb-view --font-file {path to font} --text-file {path to text file} --output-file '{sample}.png'
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
* hb-shape shows glyph selection and positioning
|
||
|
|
|
||
|
|
### Fontview
|
||
|
|
* Fontview displays the text.
|
||
|
|
|
||
|
|
### Fontdiff
|
||
|
|
* Fontdiff displays the text using two versions of the font side by side.
