2014年9月25日 · RGB888 is 24-bit, not 8-bit. It has Three channels with 8 bits per channel, ARGB8888 It has Four channels with 8 bits per channel. Alpha value is 0-255, where 0 being fully transparent and 255 being fully opaque. ARGB_8888 Documentation says: Each pixel is …

2015年11月27日 · So RGB24 is a tightly packed three byte format (RRGGBB), while RGB888 is a four byte format with the first byte going ignored (XXRRGGBB). So the format is just confusingly named and XRGB8888 would be a more appropriate name. Don't know why they called it RGB888 instead of XRGB8888, but they leave the leading X away on other formats as well.

2013年10月2日 · Yes, libjpeg and libpng can convert the image to RGB888. RGB888 is a simple format where the red, green and blue component of each pixel uses 1 byte (8 bit). In libpng, RGB888 is the format PNG_COLOR_TYPE_RGB with a bit depth 8. But it isn't a single function you can call. You will need to study the documentation of libpng. –

2019年7月9日 · My problem is that the Besler camera gives frames in RGB888 format. but eglCreateImageKHR is working only if I give RGBA8888 format . If I pass RGB888 to eglCreateImageKHR it gives black screen and also egl image returned is 0. If I convert RGB888 data to RGBA8888 it works . but I don't want to do extra conversions for better performance.

2013年9月11日 · First, we will look at converting RGB565 to RGB888. We assume there are eight 16-bit pixels in register q0, and we would like to separate reds, greens and blues into 8-bit elements across three registers d2 to d4. vshr.u8 q1, q0, #3 @ shift red elements right by three bits, @ discarding the green bits at the bottom of

Hi, While working with gnome-shell (X11, cogl & mutter doing window compositing) we see a strange issue when eglCreateImageKHR() is used to get an OpenGLESv2 texture

2010年3月14日 · You may notice that, if you use the code above to convert to RGB888 format, your whites aren't quite white. This is because, for each channel, the lowest two or three bits are zero, rather than one; a white represented in RGB565 as (0x1F, 0x3F, 0x1F) becomes (0xF8, 0xFC, 0xF8) in RGB888.
