32bit Float Density Regression #3511

Description

@jonnyawsom3

Describe the bug

Nightly builds result in bpp higher than the uncompressed source. Using 0.10.2 correctly reduces file size.

cjxl metro_noord_2k.hdr.pfm metro.hdr.jxl -d 0
JPEG XL encoder v0.10.2 e148959 [AVX2,SSE2]
Encoding [Modular, lossless, effort: 7]
Compressed to 4144.0 kB (15.808 bpp).
2048 x 1024,  0.200 MP/s [0.20, 0.20], , 1 reps, 16 threads.

cjxl metro_noord_2k.hdr.pfm metro.hdr.jxl -d 0
JPEG XL encoder v0.10.2 60dfa1b [AVX2,SSE2]
Encoding [Modular, lossless, effort: 7]
Compressed to 15722.2 kB (59.976 bpp).

To Reproduce
metro hdr jxl
Run cjxl -d 0 metro.hdr.jxl Test.jxl on 0.10.2 and nightly

Environment

  • OS: Windows
  • CPU type: x86_64
