Canvas

Please add possibility to read red, green and blue values (or RGB code) at given point by Canvas object.

It'd be very slow, what precise use are you thinking of?

You could transfer it to the Image Manipulator plugin and read values using that.

I need visual map that is also an array of 3 low precision integers. Canvas with reading RGB would be best. In Multimedia Fusion there is Overlay object which does that, but I wanted to port my app to Construct. What about second plugin, identical to Canvas but with reading possibility?

Well, I was hoping that I might use Canvas, as it's faster.

Reading pixels directly from a Direct-X texture is far slower than the method I suggested, using the 'copy from sprite' action of Image Manipulator, and then using the Get R/G/B expressions of it.

Oh, well, then it's great I just didn't know it. Thanks!

It should probably be renamed 'copy from sprite/canvas', but it's very handy as it is .

Well, that doesn't work for me.

Ah it was fixed for the next build so I didn't notice it.

Was setting R, G or B in Image Manipulator fixed too? Because now it's default to use color selector for it, which crashes application (because most colors don't fit in 0-255). It should be always expression and, if possible, greyscale selector or something.
