Ik denk wel een antwoord heb voor je vraag, of je er blij van wordt is ten tweede:
"16-Bit RGB
If you program, you know 16 bits makes up two bytes. There are three major 16-bit formats used: R5G6B5, R5G5B5A1, and R5G5B5X1. Before you run away screaming, take a moment and look at the names. Figure them out? The channel is given a letter (R - Red, G - Green, B - Blue, and A - Alpha), and following the name is the number of bits that represent it. When R5G5B5A1 is used, the red, green, and blue channels are represented with five bits, and alpha is represented with one, meaning it has a maximum of two values (transparent or opaque). The last one, R5G5B5X1 is the same as the previous, but the X1 (which used to be A1) is disreguarded totally, meaning the value is irrelevent when drawing the color. The first one simply leaves out the last channel and gives an extra bit to green. Why? Who knows. ""
Bij sommige mappings, word A(lpha) niet gebruikt.. ik denk dat dit hier het geval is.
dus kan je geen Alpha gebruiken
Heb het zelf al eens eerder gehad, lijkt me niet op te lossen.

| Format16bppArgb1555: The pixel format is 16 bits per pixel. The color information specifies 32,768 shades of color, of which 5 bits are red, 5 bits are green, 5 bits are blue, and [b]1 bit is alpha[/b].
Format16bppGrayScale: The pixel format is 16 bits per pixel. The color information specifies 65536 shades of gray.
Format16bppRgb555:
Specifies that the format is 16 bits per pixel; 5 bits each are used for the red, green, and blue components. [b]The remaining bit is not used[/b].
Format16bppRgb565:
Specifies that the format is 16 bits per pixel; 5 bits are used for the red component, 6 bits are used for the green component, and 5 bits are used for the blue component. [b]no alpha[/b] |
