OpenEXR, or EXR for short, is a deep raster format developed by ILM and broadly used in the computer-graphics industry, both visual effects and animation. OpenEXR's multi-resolution and arbitrary channel format makes it appealing for compositing, as it alleviates several painful elements of the process.

Multi-view OpenEXR images with a number of formatting variations (scan lines vs. tiles, image channels, etc.). All images contain at least a left-eye and a right-eye view suitable for presentation on a stereo display.

OpenEXR provides the specification and reference implementation of the EXR file format, the professional-grade image storage format of the motion picture industry. The purpose of EXR format is to accurately and efficiently represent high-dynamic-range scene-linear image data.

2023年4月20日 · An EXR file is a raster image stored in the OpenEXR format, a high dynamic-range (HDR) image format developed by Academy Software Foundation (ASWF). The EXR format supports multi-layer images, lossy and lossless compression, and 16-bit and 32-bit pixels.

2017年9月27日 · The OpenEXR python module provides full support for reading and writing all types of .exr image files, including scanline, tiled, deep, mult-part, multi-view, and multi-resolution images with pixel types of unsigned 32-bit integers and 16- and 32-bit floats.

The OpenHDR Viewer allows you to view high dynamic range images in your browser. Preview images, explore different looks, and upload it when you wish to share your creation with others.

2023年6月12日 · An EXR file is an OpenEXR bitmap file, an open-source HDR image file format. Here's how to open one or convert one to a different image format.

OpenEXR provides the specification and reference implementation of the EXR file format, the professional-grade image storage format of the motion picture industry. The purpose of EXR format is to accurately and efficiently represent high-dynamic-range scene-linear image data and associated metadata, with strong support for multi-part, multi ...

The OpenEXR python module provides basic access to data in EXR image files. The read and write methods use python dictionaries for header metadata and numpy arrays for pixel data. To install the OpenEXR module:

OpenEXR ，或简称为exr格式，是一种 开放标准 的 高动态范围 图像格式 ，在计算机图形学里被广泛用于存储图像数据，但也可以存储一些后期合成处理所需的数据。
