So, anyways, I'm trying to make a gradient from 0% alpha to 100% alpha and allow my self to choose the size of the gradient and the distance from the edge of the photo/selection. In it's current state, I can get it to go from 195 alpha to 255, which isn't what I want .
Thank you for all your help!
#region UICode
int Amount1=60; //[0,255]Length
int Amount2=50; //[0,255]Distance from Edge
#endregion
void Render(Surface dst, Surface src, Rectangle rect)
{
// Delete any of these lines you don't need
Rectangle selection = this.EnvironmentParameters.GetSelection(src.Bounds).GetBoundsInt();
//long CenterX = (long)(((selection.Right - selection.Left) / 2)+selection.Left);
long temp = 0;
long LeftX = (long)(selection.Left + Amount1);
long LeftMath, RightMath;
long RightX = (long)(((selection.Right - selection.Left))+selection.Left - Amount1);
//long CenterY = (long)(((selection.Bottom - selection.Top) / 2)+selection.Top);
ColorBgra PrimaryColor = (ColorBgra)EnvironmentParameters.PrimaryColor;
ColorBgra CurrentPixel;
for(int y = rect.Top; y < rect.Bottom; y++)
{
for (int x = rect.Left; x < rect.Right; x++)
{
CurrentPixel = src[x,y];
// TODO: Add pixel processing code here
if ((x <= LeftX))
{
temp = x;
LeftMath = temp / LeftX;
// Access RGBA values this way, for example:
CurrentPixel.R = (byte)CurrentPixel.R;
CurrentPixel.G = (byte)CurrentPixel.G;
CurrentPixel.B = (byte)CurrentPixel.B;
//temp = temp-LeftX-LeftMath;
//temp=x;
temp=LeftX-temp-LeftMath;
if(temp>255)temp=255;else if(temp<0)temp=100;
CurrentPixel.A = (byte)(-temp);
}
else if ((x >= RightX))
{
RightMath = x / RightX;
// Access RGBA values this way, for example:
CurrentPixel.R = (byte)CurrentPixel.R;
CurrentPixel.G = (byte)CurrentPixel.G;
CurrentPixel.B = (byte)CurrentPixel.B;
temp = x-RightX+RightMath;
CurrentPixel.A = (byte)(temp*255);
}

}
}
