JPEG XL encoder v0.7.0 [AVX2,SSE4,SSSE3,Unknown]
Getting pixel data.



Reproducible: Always

Steps to Reproduce:
1. Install libjxl-tools.
2. Try to encode file.
3. No output file is produced.
Actual Results:  
Output file is not created by the encoder.

Expected Results:  
.jxl file output is expected.

After some testing, I found that it cannot encode and decode png files. It
works if I use ppm as source file.
