I would like to draw a color wheel on my iPhone Application, how can I do so?
What is the Algorithm behind the color wheel? Thank you.
If you are familiar with HSA color system the algorithm will be simple.
A color wheel depicts Hue and Saturation. The hue varies with the angle, and the saturation varies with the radius. For more information you can take a look at http://www.stackoverflow.com/questions/4235072/math-behind-the-colour-wheel

I'm trying to draw using finger on any image or any shape or inside a particular shape eg rectangle. How to do that
Any idea would be appreciated.
For that purpose the InkCanvas is designed. You can surely find tutorials and some MSDN docs about this. Even other SO questions.

I'm looking for some guidance here. I primarily am a frontend developer. What I am trying to figure out is how an algorithm can be implemented to count kernels on an ear of corn.
From my initial research it seems there are a couple of different directions to go. Main ones I have seen are a SIRF type of implementation and others call for conversion to the HSV color space or LAB color space in order to then to normalizations and then counting.
For reference usually the corn that will be counted is "dent" corn. Here is an example:
This will be implemented in VB.net, but I can always translate the algorithm if needed.
Thank you for your help!

Hey I am trying to design an interface for android application. Since I am a beginner to Android and Photoshop, I am having a few issues.
Most important of them is that I try to draw on larger than required canvas ( say, A4 siza; because i am not used to precise drawing) and then duplicate those high resolution (300dpi) layers to a smaller canvas with high resolution to create nine-patch files.
But I am unable to copy those layers; nothing shows up on canvas even if I have layers in the side box.
I have tried it multiple times but same result. Kindly guide me how to properly make a nine-patch image?

I am trying to create a simple scatter plot with PlotSymbols for when I hit a point of data. I have all of that implemented, but the line and the symbols are all one color that blends in making it hard to see the data. I know I could make the symbols bigger, but I am hoping to try and avoid that.
From the few screen shots that I saw in the examples I saw the ability to do this, but only for the ellipse symbol. Is there any way to do this for other symbols as I am currently using the rectangle.
Every plot symbol has a lineStyle and a fill. You can mix and match to get whatever look you want.
