PixelViewer is an image viewer designed for software developers, graphics engineers and users who need to inspect image data at a lower level than conventional image viewers allow. Alongside familiar picture formats, it can interpret raw pixel buffers that do not contain the headers or metadata required by ordinary viewing applications.
The program is particularly useful when debugging image processing pipelines, camera output, graphics rendering and colour conversion. Users can specify how pixel data is organised, including channel layouts, row strides, offsets and image dimensions.
PixelViewer also includes tools for examining colour spaces, HDR content, individual pixels and image histograms. Its support for multiple frames and alternative colour representations makes it suitable for inspecting technical image data as well as everyday graphics.
This is free and open source software.
