View ArticleSetting decimal point for formatting floats.
In Processing 1.5 I used Locale.setDefault(Locale.US); in the setup() to make nf() produce decimal points for floats. If I did not, it would use decimal comma, as my window-pc is localized for Denmark....

I don't know the answer right now, but I suggest to look at the examples coming with Processing:PDE > File > Examples > Libraries > MinimI am pretty sure there is one example showing how to...

I don't know the answer to this either, but I suspect that it may be possible to do what you want by making low-level GL calls directly from within your sketch (circumventing the Processing interface...

Cannot figure out why alpha is acting strange here!
Hi all. I am having what appears to be a strange bug, but I'm sure I'm doing something stupid.I have a "HeatPoint" class which is basically a point that is assigned a color value. From that color...

All pixels drawn at the main screen surface (PGraphics g) are 100% opaque!Processing converts all transparent colors into an equivalent opaque one!Alpha attribute is only preserved in separate PImage...

Thank you for your response.I still don't understand why it won't work though. I changed the code to render the "fading circle" in PGraphics: pg.beginDraw(); pg.noStroke(); pg.background(0);...

Re : Cannot figure out why alpha is acting strange here!
In the end, all colors become 100% opaque! Once you stamp your PGraphics instance at the main canvas, any alpha color of it is transformed into an opaque equivalent too!

So basically what you're saying is that transparency is not possible.I don't understand at all since I have made things overlapping and transparent before. Actually it works fine with the original...

Transparency works! It's just that Processing transforms a transparent color into an opaque equivalent when it is drawn at the main screen!The deal is, the color code you draw isn't the same you read...

Reading your code, taking notes...- distanceBetween() duplicates the dist() function in Processing! Beside, no need for abs(), since you square the value anyway.- You can use x += 4 as increment of the...

Thank you Phil for your help of both the main issue and also suggesting better/more efficient programming solutions. I will keep hacking away at this problem as well.Thanks again.

GoToLoop, the second example given by lasko25 already tried your suggestion (which was my guess too...).That said, indeed the pixels on the main graphics are opaque, but the rectangles drawn over them...

PhiLho, thank you so much!I can certainly work with this, but while the thread is still hot I figured I'd ask one more question.The code you provided is slightly problematic in reaching my end goal (I...

"Not really a question I suppose."Indeed, I don't see a question mark... At the end of draw(), they are all unified. You can do additional processing of the resulting image there. Or draw them all in a...
