Hi,

I have a image of surfboard(i.e. the object i have to color) (in any format)..
I want to set color to surfboard only.
Also I have to add border to surfboard with different color.

C#

public static Bitmap setColour(string NewFileName) 
{ 
   ColorDialog cDia = new ColorDialog(); 
   if (cDia.ShowDialog() == DialogResult.OK) 
   { 
     Graphics NewGraphics = Graphics.FromImage(NewBitmap); 
     float[][] FloatColorMatrix = { new float[] { float.Parse(cDia.Color.R.ToString())/255,0,0,0,0}, new float[] { 0,float.Parse(cDia.Color.G.ToString())/255,0,0,0}, new float[] { 0,0,float.Parse(cDia.Color.B.ToString())/255,0,0}, new float[] { 0,0,0,1,0 }, new float[] { 0.11F,0.0F,0.0F,0.0F,1} }; 
     ColorMatrix NewColorMatrix = new ColorMatrix(FloatColorMatrix);
     ImageAttributes Attributes = new ImageAttributes(); 
     Attributes.SetColorMatrix(NewColorMatrix, ColorMatrixFlag.Default, ColorAdjustType.Default); 
     NewGraphics.DrawImage(NewBitmap, new Rectangle(0, 0, NewBitmap.Width, NewBitmap.Height), 0, 0, NewBitmap.Width, NewBitmap.Height, System.Drawing.GraphicsUnit.Pixel, Attributes); 
     NewGraphics.Dispose(); 
   } 
   return NewBitmap; 
}

Hi, I suggested in answer to your last question that you describe your problem better but sadly I think there is still insufficient information. It is not even clear if this is project that you have started or just an idea. Try to explain exactly what you need help with in a Question. Best of Luck :-)

currently I m converting image into bitmap and using graphics object applying color matrix over it..
But doing this all image color is change but i want to change only color of real object in the image..
Following is the code i have done..
Plz correct my solution or suggest me other proper solution for it..

public static Bitmap setColour(string NewFileName)
{
ColorDialog cDia = new ColorDialog();
if (cDia.ShowDialog() == DialogResult.OK)
{

Graphics NewGraphics = Graphics.FromImage(NewBitmap);

float[][] FloatColorMatrix =
{
new float[] { float.Parse(cDia.Color.R.ToString())/255,0,0,0,0},
new float[] { 0,float.Parse(cDia.Color.G.ToString())/255,0,0,0},
new float[] { 0,0,float.Parse(cDia.Color.B.ToString())/255,0,0},
new float[] { 0,0,0,1,0 },
new float[] { 0.11F,0.0F,0.0F,0.0F,1}

};

ColorMatrix NewColorMatrix = new ColorMatrix(FloatColorMatrix);
ImageAttributes Attributes = new ImageAttributes();
Attributes.SetColorMatrix(NewColorMatrix, ColorMatrixFlag.Default, ColorAdjustType.Default);
NewGraphics.DrawImage(NewBitmap, new Rectangle(0, 0, NewBitmap.Width, NewBitmap.Height), 0, 0, NewBitmap.Width, NewBitmap.Height, System.Drawing.GraphicsUnit.Pixel, Attributes);
NewGraphics.Dispose();

}
return NewBitmap;
}

and returing bitmap is set to picturebox...

Hi, this is a much better question but by putting it in a comment it is really hard to read, so put it in a NEW Question, with the code formated properly and we'll see if either I or someone else can help. Cheers. :-)
