private Blend GetRandomBlend()
{
Random rnd = new Random();
int count = rnd.Next(11);
Blend blend = new Blend();
if (count > 0)
{
float[] f = new float[count];
float[] p = new float[count];
for (int i = 0; i < f.Length; i++)
{
f[i] = Convert.ToSingle(rnd.NextDouble());
p[i] = Convert.ToSingle(rnd.NextDouble());
}
blend.Factors = f.OrderBy(e => e).ToArray();
blend.Positions = p.OrderBy(e => e).ToArray();
}
return blend;
}
But when I assign this Blend to LinearGradientBrush there is an exeption that says: "Parameter is not valid". What is wrong with it? How can I find criteria like this? There is nothing in the documentation about these types of criteria for Blend and some
other classes.
// Make your positions and factors start with 0 and end with 1
blend.Positions[0] = 0;
blend.Positions[blend.Positions.Length - 1] = 1;
blend.Factors[0] = 0;
blend.Factors[blend.Factors.Length - 1] = 1;
return blend;
I'm afraid I no longer use this forum due to the new point allocation system.

Hi
I wrote a method to generate random Blend:
private Blend GetRandomBlend() { Random rnd = new Random(); int count = rnd.Next(11); Blend blend = new Blend(); if (count > 0) { float[] f = new float[count]; float[] p = new float[count]; for (int i = 0; i < f.Length; i++) { f[i] = Convert.ToSingle(rnd.NextDouble()); p[i] = Convert.ToSingle(rnd.NextDouble()); } blend.Factors = f.OrderBy(e => e).ToArray(); blend.Positions = p.OrderBy(e => e).ToArray(); } return blend; }But when I assign this Blend to LinearGradientBrush there is an exeption that says: "Parameter is not valid". What is wrong with it? How can I find criteria like this? There is nothing in the documentation about these types of criteria for Blend and some other classes.
Thanks

Hi
Actually only Position needs these assignments.
Thanks

That's what I thought, but I occasionally got errors still...they only stopped when Factors had proper stat/end points too.
