About the HDR format
HDR — Radiance RGBE High Dynamic Range
HDR (Radiance .hdr) is a high dynamic range image format developed for the Radiance rendering system. It stores luminance information far beyond standard 8-bit images using a shared-exponent encoding, making it the standard for HDR environment maps in 3D rendering.
Common uses
- 3D rendering environment maps (IBL)
- HDR panorama photography storage
- VFX and CGI lighting reference images
- Tone mapping source images
About the XC format
XC — Constant Color Canvas
XC is an ImageMagick canvas generator that creates a solid-color image of any specified color and dimensions. Like PLASMA, it is not a stored file format but a built-in generator used to create blank colored canvases as starting points for image composition operations.
Common uses
- Creating solid-color background images
- Initializing canvas for ImageMagick compositing
- Generating color swatches and test images
- Blank canvas base for layered image operations
