HDR to CUR conversion is the process of transforming a High Dynamic Range (HDR) image file into a Windows cursor (CUR) file format so the image can be used as a system cursor or icon. The conversion typically involves scaling, color and alpha-channel adjustments, and packaging one or more image sizes into the CUR container while preserving transparency where possible.

HDR files typically use the image/hdr MIME type and are associated with radiance or high dynamic range image formats. CUR files use the image/x-icon MIME type and are encoded with cursor-specific information including hotspot coordinates. HDR is commonly used in professional imaging software, whereas CUR files are primarily used in operating system interfaces.
The CUR (.CUR) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like HDR.
While specific technical details aren't available here, CUR files generally serve the purpose of storing image effectively within their domain.

HDR files store high dynamic range images with a wide range of luminance, ideal for photography and imaging applications. CUR files are specialized cursor icon files used primarily in Windows environments to customize mouse pointers. While HDR focuses on image quality and color depth, CUR emphasizes usability and interface customization.
Keep source HDR exposures moderate; tone-map HDR to a standard dynamic range image (8-bit or 32-bit RGBA) before creating CUR to avoid clipping or washed-out cursors.
Target cursor sizes: create and include multiple sizes (16x16, 24x24, 32x32, 48x48) to ensure crisp appearance at different display scales; avoid very large sizes since CUR is intended for small graphics.
Preserve transparency: export or convert to an alpha-enabled image (RGBA) so the CUR supports smooth edges and anti-aliased cursors; fully opaque conversions will look blocky.
Batch conversion: for many files, use a tool or script that batch tone-maps HDR to consistent exposure settings, then generates CUR files with standard sizes; this keeps results uniform.

Format limitation: CUR does not retain HDR floating-point data or extended dynamic range—all HDR content must be tone-mapped to standard display range before or during conversion.
