example of set pixel in action?

sambean · 11 May 2006

Have a look in the sonogram of me analysis kit.. It uses set pixel to draw the fft..

You need to first use the create bitmap to generate a 'canvas' for you to work on. Width and Height in pixels, step set normally to 8. If you connect this to a 'draw bitmap' module, you will see nothing as it's blank!

But you can now connect the bitmap to a set pixel module, choose a colour and a coordinate and set it, and in your view you should see a single pixel.. From there you could set up some loop or mouse action to draw more points..

Let me know if it works..

On the assumption Sam's sonogram isn't quite as 'simple' as you were looking for...

setPixel.osm

Some things about Set Pixel.

1) as you will have noticed, it has no outputs. It's effect feeds back through the bitmap input to the source bitmap.

2) its inputs are in pixels units and not grid points

3) its effects can be saved with the SM file

Hope this helps.
