Hi, @mesa in your previous code the colors displayed in the canvas window are 32 bit colors whereas in the demivec code the 24bit colors are respected as well as their values ​​ it is just that the display of the alpha value must be blocked at 255 because with "Color Picker" the colors wit...

Hello, Demivec, thank you for your code which I modified a little to compare it with ImageGadget using the IDE tool: Color Picker with alpha mode, we can clearly see the differences in the displays. so CanvasGadget() arrived at the beginning of 2012 we are in 2023 since we have processors which will...

hi, here is an alpha test in 24bit we obtain a color close truncated Best Regard If OpenWindow(0, 0, 0, 300,300, "Test Canvas RGBA (alpha in 24bit)", #PB_Window_SystemMenu | #PB_Window_ScreenCentered) c.i = 0 c1.i = 0 b1.i = RGBA(Random(255),Random(105), 0, 100) b2.i = RGBA(0, Random(255),...

hi, @Caronte3D
the usefulness of alpha when drawing with alpha objects overlaid
on the canvas you will have colors whose alpha value you cannot get with the point(xy) command
and that's annoying because any drawing software does this perfectly

hi, why so much discussion around a request as simple as this one.
To sum up,
Fred should give us the alpha channel for CanvasGadget()
all is said

hi, Demivec thank you, ok there is ImageGadget() to do that thank you. but like CanvasGadget()
is designed for drawing, I don't see why it should stay 24 bit
while we now have 64-bit processors and all images have
at least 32 bit why stay with canvasGadget in 24 bit
Best Regard

Hi, Stargate ok thank you,
but the canvas is a drawing surface where you can use transparency but you can't recover color from fades to transparency
so why stay in 24 bits i think it's time now that the machines are more advanced with giga of ram so why not CanvasGadget

hello Fred it seems to me that it would be time to have with CanvasGadget the Point(x,y) function
which could return us a color in RGBA
