2014年8月24日 · To pack a colour in 2 bytes = 16 bits, you have 2 commons ways: encode the RGB components in 5 bits each. This is easiest to code/decode and provide a consistent gradation, at the expense of wasting 1 bit.
C#: How to load a RAW image (format: rgb565) into a Bitmap?
2019年4月20日 · Next, I insert the image data (raw format: rgb565) into the payload section of the empty Bitmap. Finally, I display the modified Bitmap within a PictureBox. My problem: Everything works fine, but the testimage is displayed with diagonal stripes instead of vertical stripes (see links below). Original rgb565 raw image: Original rgb565 raw image
Combining two 16 bits RGB colors with alpha blending
unsigned short calcColor_RGB565(unsigned short background_RGB565, unsigned short foreground_RGB565, unsigned char opacity) calcColor_RGB565(0x0000, 0xFFFF, 128) would result 0x8410 (or 0x1084, it isn't important because I send two separate bytes to the TFT so I would just invert the order if needed)
c - ASCII characters in RGB565 format - Stack Overflow
2015年8月17日 · One RGB565 value indeed is a 16-bit short, but are you aware that it will only draw one pixel as well? So you would need 8*16 shorts to draw a single character (and then only in a single, fixed color). Hence my suggestion of drawing the bitwise bitmap one bit at a time, in any color (= RGB565 value) you want. –

2012年7月25日 · I Created my own optimized ordered dithering from 24/32bit RGB color to 16bit RGB565 color, that seperate tresshold into subpixel (Used in my AROMA project). It was way faster then Floyd-Steinberg, because there is no expensive calculations (specially no multiplies and divs calculations ), and able to used on animations because it used fixed ...
