Hi,
I want to manipulate the alpha of different individual textures. When I use alpha, I cannot give it an other number then 0 or 1, which is not what I want. I would like to change the alpha of a texture a little bit, so it blends into the other textures. Also, when alpha is 1, the white in the images becomes too white [almost overexposed].
I would like to use something like the pix_mix object, but this is meant for two images on one texture. The example blending.pd is also meant for two images on one texture.
Does someone know the object that I want?
Thanks, Sara

...um, are you sure about this? alpha always is between 0 and 1: in pd, you have to hold down the shift key when changing a number box to get intervening float values...if that doesn't work, why not divide by some value?

I tried to use a slider which moves between 0 and 1, but it the alpha-object only seems to take a 0 or a one. That's why I was looking for another 'alpha-object' which is able to take values between 0 or 1.

hi sara,
use pix_color with R G B Alpha

Hey chica!
Thanks; I already figured out something else; by using the alpha [1] and change the last inlet of the message to the color-object; that does the trick too.
Ciao,
Sara

Hello list
After several years in a closet i finally revived my old prophet 600 and fixed the midiout it is apparently the first hybrid digital/analog synth made by sequential circuits back in the late 70s it works nice and has 2 wheels for midi control that i would like to exploit for controlling GEM the bendin defaults while running 5.reference in pd help ranges 1664-16320
anyone done anything wackadelic with bendin values that can give a tip?
cheers~
Pat

That's a bit unusual, but if it stays that way, you can always scale that range to something more fit for your needs by substracting 1664, dividing by 16320-1664 and multiplying by x for your desired 0 to x range.
