The [_RGBA](_RGBA) function returns the closest palette index (legacy SCREEN modes) OR the 32-bit [LONG](LONG) color value (32-bit screens). ## Syntax > colorIndex~& = [_RGBA](_RGBA)(red&, green&, blue&, alpha&[, imageHandle&]**)** * The value returned is either the closest color attribute number or a 32-bit [_UNSIGNED](_UNSIGNED) [LONG](LONG) color value. * **Return variable types must be [LONG](LONG) or the resulting color may lose the [_BLUE](_BLUE) value.** * red& specifies the red component intensity from 0 to 255. * green& specifies the green component intensity from 0 to 255. * blue& specifies the blue component intensity from 0 to 255. * The [_ALPHA](_ALPHA) value can be set to make the color transparent (0), opaque (255) or somewhere in between. * Parameter values outside of the 0 to 255 range are clipped. * Returns [LONG](LONG) 32-bit hexadecimal values from **&H00000000** to **&HFFFFFFFF** with varying [_ALPHA](_ALPHA) transparency. * When [LONG](LONG) values are [PUT](PUT) to file, the ARGB values become BGRA. Use [LEFT$](LEFT$)([MKL$](MKL$)(colorIndex~&), 3) to place 3 colors. * If imageHandle& is omitted, the image is assumed to be the current [_DEST](_DEST) or [SCREEN](SCREEN) page. * Allows the blending of pixel colors red, green and blue to create any of 16 million colors. * **NOTE: Default 32-bit backgrounds are clear black or [_RGBA](_RGBA)(0, 0, 0, 0). Use [CLS](CLS) to make the black opaque.** ## Example(s) Setting a font's background color alpha to clear to overlay a second text color. ```vb scrn& = _NEWIMAGE(400, 400, 32) SCREEN scrn& fnt& = _LOADFONT("C:\WINDOWS\FONTS\ARIAL.TTF", 26) _FONT fnt& X% = 20 Y% = 20 COLOR _RGB(255, 255, 255), _RGB(0, 0, 0) 'Foreground set to WHITE background to BLACK _PRINTSTRING (X%, Y%), "Hello World" COLOR _RGB(255, 0, 0), _RGBA(0, 0, 0, 0) 'Foreground set to RED background to TRANSPARENT BLACK _PRINTSTRING (X% + 2, Y% + 2), "Hello World" END ``` *Explanation:* [_PRINTSTRING](_PRINTSTRING) allows text or font colors to be alpha blended in 32 bit screens. ## See Also * [_RGB](_RGB), [_RGB32](_RGB32), [_RGBA32](_RGBA32) * [_RED](_RED), [_GREEN](_GREEN), [_BLUE](_BLUE) * [_LOADIMAGE](_LOADIMAGE) * [_PRINTSTRING](_PRINTSTRING) * [HEX$ 32 Bit Values](HEX$-32-Bit-Values), [POINT](POINT) * [SAVEIMAGE](SAVEIMAGE) * [Hexadecimal Color Values](http://www.w3schools.com/html/html_colornames.asp)
