![]() ![]() It is listed in the PixelFormat enum (as Format16bppGrayScale ), but it is not actually supported. That said, GDI+ doesnt contain any support for 16-bit grayscale, no. Grayscale images just have values that give a brightness directly, without any palette involved. Often, you only need grayscale values of the color channel, so we also added the grayscale mode to all color systems that let you extract a channel using only gray tones. Indexed means the pixels refer to indices on a colour palette. You can also select multiple color channels in the options and draw and generate several PNGs of different color channels at once. This online program splits the PNG colors into individual channels and draws a PNG of a single color channel. To save ndarray as an image file, set the file path and ndarray object to cv2.imwrite (). My first try was using ffmpeg: ffmpeg -y -framerate 1 -i input.png -c:v libx265 -x265-params 'lossless1' output.mp4 Unfortunately the output is not reversible. At the moment I have the data as 16-bit PNG files. Lightness defines how much white light there is. PNG grayscale images support the widest range of pixel depths of any image type. Because I need to be able to reconstruct the original 12bit signal, the compression needs to be losslessly reversible. ![]() The tile option will also slice the original heighmap into sequential tiles of whatever resolution you set. The scale option will output an additional heightmap which has been scaled to your resolution of choice (square resolution). Saturation defines how much color there is. By default, the script will output a full-resolution 16-Bit PNG convereted from your input data. The HSL color system, which is the most modern color system and is often used in color picker tools, uses Hue, Saturation, and Lightness as channels. The CMY and CMYK color systems, which are most often used in color printing, use three or four channels: Cyan, Magenta, Yellow, and Key (black). The RGBA model also includes the "A" parameter that is the Alpha channel or transparency of the color. The reference Load Image node works very well to load PNG images in full 16 bit grayscale. For example, the RGB color system, which is the most widely used color scheme in computers and monitors, expresses each color in a picture using a combination of three colors: Red, Green, and Blue. As you may know, in computing and digital systems, images are represented using color systems consisting of several independent color components. This browser-based utility allows you to extract color channels from PNG (Portable Network Graphics) pictures. var height bitmap.PixelHeight var pixels new ushortwidth height bitmap.CopyPixels(pixels, 2 width, 0) Access an individual pixel value directly from that array: var x 100 var y 200 var pixel (int)pixelswidth y + x In order to convert the 16bpp pixel array into a 8bpp array, just divide each pixel value by 256. ![]()
