Will this support gain map inspection?
Yes. Gain map parsing and preview are part of the planned core feature set.
UltraHDR JPEG Workbench (Preview Build)
Examples
UltraHDR JPEG Tool
Read and write UltraHDR JPEG with SDR/HDR preview modes and tone mapping transformations.
What This UltraHDR JPEG Tool Covers
This page is the dedicated entry for UltraHDR JPEG workflows, including gain-map aware decode/encode and mapped preview output.
Supported UltraHDR workflow scope
- Input focus: UltraHDR JPEG and gain-map based JPEG assets used for modern HDR image delivery.
- Output scope: browser-side UltraHDR exports plus preview validation across SDR and HDR modes.
- Best fit: JPEG gain-map inspection, mobile-oriented HDR delivery checks, and export preset validation.
When to use this tool
- Inspect gain-map based JPEG assets before shipping them to modern HDR-capable viewers and mobile devices.
- Compare SDR and HDR preview behavior when tone mapping and export settings still need tuning.
- Export UltraHDR JPEG outputs while keeping preview and delivery settings aligned.
