The [_RGB32](_RGB32) function returns the 32-bit *RGBA* color value with specified red, green and blue component intensities and optional alpha. ## Syntax *Original syntax*: > color32value~& = [_RGB32](_RGB32)(red&, green&, blue&) *Alternative Syntax 2*: > color32value~& = [_RGB32](_RGB32)(red&, green&, blue&, alpha&) *Alternative Syntax 3*: > color32value~& = [_RGB32](_RGB32)(intensity&, alpha&) *Alternative Syntax 4*: > color32value~& = [_RGB32](_RGB32)(intensity&) ## Parameter(s) * red& specifies the red [LONG](LONG) component intensity from 0 to 255. * green& specifies the green [LONG](LONG) component intensity from 0 to 255. * blue& specifies the blue [LONG](LONG) component intensity from 0 to 255. * alpha& specifies the alpha [LONG](LONG) component from 0 to 255. * intensity& specifies the red, green and blue [LONG](LONG) components intensity from 0 to 255 simultaneously, to generate a shade of gray. ## Description * The value returned is always a 32-bit [_UNSIGNED](_UNSIGNED) [LONG](LONG) color value, as is the [POINT](POINT) value. * **Return variable types must be [_UNSIGNED](_UNSIGNED) [LONG](LONG) or [LONG](LONG), otherwise resulting color may lose the [_BLUE](_BLUE) value.** * Parameter values outside of the 0 to 255 range are clipped. * Returns [LONG](LONG) 32 bit hexadecimal values from **&H00000000** to **&HFFFFFFFF**. * When [LONG](LONG) values are [PUT](PUT) to file, the ARGB values become BGRA. Use [LEFT$](LEFT$)([MKL$](MKL$)(color32value~&), 3) to place 3 colors. * **NOTE: Default 32-bit backgrounds are clear black or [_RGB32](_RGB32)(0, 0). Use [CLS](CLS) to make the black opaque.** ## Availability * Alternative syntax available with version 1.3 and up. ## Example(s) Converting the color port RGB intensity palette values 0 to 63 to 32 bit hexadecimal values. ```vb SCREEN 12 DIM hex32$(15) FOR attribute = 1 TO 15 OUT &H3C7, attribute 'set color attribute to read red = INP(&H3C9) * 4 'multiply by 4 to convert intensity to 0 to 255 RGB values grn = INP(&H3C9) * 4 blu = INP(&H3C9) * 4 hex32$(attribute) = "&H" + HEX$(_RGB32(red, grn, blu)) 'always returns the 32 bit value COLOR attribute PRINT "COLOR" + STR$(_RGB(red, grn, blu)) + " = " + hex32$(attribute) 'closest attribute NEXT ``` ```text COLOR 1 = &HFF0000A8 COLOR 2 = &HFF00A800 COLOR 3 = &HFF00A8A8 COLOR 4 = &HFFA80000 COLOR 5 = &HFFA800A8 COLOR 6 = &HFFA85400 COLOR 7 = &HFFA8A8A8 COLOR 8 = &HFF545454 COLOR 9 = &HFF5454FC COLOR 10 = &HFF54FC54 COLOR 11 = &HFF54FCFC COLOR 12 = &HFFFC5454 COLOR 13 = &HFFFC54FC COLOR 14 = &HFFFCFC54 COLOR 15 = &HFFFCFCFC ``` > *Note:* This procedure also shows how the returns from [_RGB](_RGB) and [_RGB32](_RGB32) differ in a non-32 bit screen mode. Working with 32 bit colors. ```vb SCREEN _NEWIMAGE(640, 480, 32) CLS , _RGB32(0, 0, 128) 'deep blue background LINE (100, 100)-(540, 380), _RGB(255, 0, 0), BF ' a red box LINE (200, 200)-(440, 280), _RGB(0, 255, 0), BF ' a green box SLEEP 'Just so we can see our pretty background before we print anything on it.
