The transfer function or gamma curve determines how each component in the color space is encoded. The range of colors expressable by the primary colors is called the gamut, and a color space that can represent a wider range of colors is also known as a wide-gamut color space. ![]() The primaries are defined by three primary colors that represent exactly how red, green, and blue look in this particular color space, and a white color that represents where and how bright pure white is. The primaries defines the axes of the color space, and the transfer function how values are mapped on the axes. QColorSpace can also represent color spaces defined by ICC profiles or embedded in images, that do not otherwise fit the predefined color spaces.Ī color space can generally speaking be conceived as a combination of set of primary colors and a transfer function. QColorSpace provides access to creating several predefined color spaces and can generate QColorTransforms for converting colors from one color space to another. WithTransferFunction(QColorSpace::TransferFunction transferFunction, float gamma = 0.0f) constĬolor values can be interpreted in different ways, and based on the interpretation can live in different spaces.

I’m providing these backgrounds in UHD (3840 by 2160, the size of many new monitors these days), HD (1920 by 1200, which is what you need for Zoom), and in a vertical crop for phones (9:16 ratio, 1215 by 2160). I’ll probably add to this collection as time goes on. ![]() ![]() Have fun with them! Make your colleagues guess where you are! If you have requests for other backgrounds, ask me on Twitter. They’ll work as desktop and phone backgrounds as well. Here’s a collection of images sized and cropped specifically for use as backgrounds for video. Since some services like Zoom allow you to create virtual backgrounds, I thought I might offer you the opportunity to take your home office to Mars, or the Moon, or other fun places in space. With much of the world now stuck at home due to the COVID-19 pandemic, it seems like the whole world - adults, kids, babies, cats, and dogs - is now using video-conference software to stay connected.
