A test platform to rapidly generate snapshots of render data for font validation
Security Warning: Render Lizard has known security limitations. The save.php and save-metadata.php scripts could be
misused to put arbitrary files into the data folder on your web server. Any site visitor could create or delete
results. Consider yourself warned.
New 2020-08-19: See Lindenberg Software's ImageCollector for a more polished solution inspired by Render Lizard.
Data files must at present be put into the filesystem; they cannot be uploaded by the site. Data files are a simple text file format. See the sample data file
in the folder data/1/.
- The file must be called
tests.txt. - Lines beginning with hash (
#) are ignored. - Blank lines are ignored (including whitespace)
- All other lines are tests.
#on a test line marks the start of a "note" that will be displayed in the notes column- Any one-word notes will be applied as a class to the test row.
- The note
validhas a CSS rule to make the row green.
Font suggestions can be specified for a test in the fonts.txt file. Each font
name should be on a separate line with filename.ttf,facename, one on each line.
The fonts should be included in the same folder as fonts.txt.
Each test should be a in a folder in the data folder. Folders names must be integer values at present.
You can run the site in Docker.
-
Install docker (on Linux, Windows, and Mac) - https://docker.com/
-
To Start: in terminal, run
./build.sh build start -
To Use: in browser, go to http://localhost:8060/index.php?id=1
-
To Stop: in terminal, run
./build.sh stop
Load index.php?id=<integer-test-id> in your browser, e.g. index.php?id=1
Select the font, font size and line spacing (necessary for many Indic languages). Then click Render. A new column will be added with a .png file for each test word. The results are stored on the server, so reloading the page will keep the results. This makes testing against multiple operating systems and devices straightforward.
