alpha value

The colors supported by the Android system are made up of 4 values, the first 3 RGB, which is what we often call the three primary colors (red, green, blue), and the last value is a, which is alpha. These 4 values are between 0~255. A smaller color

Rawimage logo = MainLogo.transform.FindChild ("Back/headback/logo"). Getcomponent ();void Update (){var r = LOGO.COLOR.R;var g = logo.color.g;var B = logo.color.b;var alpha = Mathf.pingpong (time.time/5f, 1);Logo.color = new Color (r, G, B,

What is hybrid? Mixing is to mix the two colors together. Specifically, the original color at a certain pixel location and the color to be painted are mixed together in some way to achieve special effects. Suppose we need to draw a scenario: to look

Alpha blending is often useful. Wait for me to study hard.I. INTRODUCTIONFirst look at the alpha channel, the alpha channel is the computer to store the image transparency information channel, it is a 8-bit grayscale channel, with 256 levels of gray

Since cloud wind started using the Pentium 200mmx CPU in March this year, it has been considering how to use the MMX technology to accelerate the Alpha hybrid operation, especially for the currently commonly used high-color mode. previously, a

When we see the OpenGL hybrid chapter, it seems that glblendfunc function parameters are hard to understand: OpenGL extracts the source color and the target color respectively and times the coefficient (the source color multiplied by the coefficient

Different devices (monitors, printers, scanners, and cameras) process different colors. Each device has a range of supported color values. Colors supported by one device may not be supported by other devices.To effectively use the color and

Direct3d uses a texture coordinate system, which consists of a horizontal U axis and a vertical v axis. The elements in the texture are determined by the U and V coordinates. It is called Texel . Note that the V axis is down. In direct3d, you
