use IrrlichtLime convert graycale to RGB

[Sharon1105]

Hi all,

I want to convert a grayscale bitmap to a color bitmap without using a color diagram.
I'm facing the problem of convert "IrrlichtLime.Video.ColorHSL" to "system.drawing.color"
Here is part of my code ...

Code: Select all

private void button2_Click(object sender, EventArgs e)
        {
            Bitmap bmp = (Bitmap)pictureBox1.Image;
            int NumRow = pictureBox1.Height;
            int numCol = pictureBox1.Width;
            Bitmap color = new Bitmap(pictureBox1.Width, pictureBox1.Height);// COLOR is the resultant matrix 
            for (int i = 0; i < NumRow; i++)
            {
                for (int j = 0; j < numCol; j++)
                {
                    System.Drawing.Color need = bmp.GetPixel(j, i);
                    int use = need.R;
                    IrrlichtLime.Video.ColorHSL clr = new IrrlichtLime.Video.ColorHSL(use,255,127);
                    
                    color.SetPixel(j, i, clr); //error appears cannot convert 'Irrlicht.video.colorHSL' to 'system.drawing.color'
                    
                     
                }
            }
            pictureBox1.Image = color;
        }

Please help...Thanks!

Before next line

Code: Select all

color.SetPixel(j, i, clr); //error appears cannot convert 'Irrlicht.video.colorHSL' to 'system.drawing.color'

you should convert type first and use it (a proper type):

Code: Select all

System.Drawing.Color clr2 = System.Drawing.Color.FromArgb((int)clr.ToColor().ARGB);

and now use clr2 instead of clr.

BUT it will not work as you might expect, because of the way how you create ColorHSL:

Code: Select all

new IrrlichtLime.Video.ColorHSL(use,255,127);

check the docs, and the value range you pass.

Code: Select all

//
// Summary:
//     Creates a color using hue, saturation and luminance.
//
// Parameters:
//   hue:
//     Hue value. Must be value between 0.0f and 360.0f.
//
//   saturation:
//     Saturation value. Must be value between 0.0f and 100.0f.
//
//   luminance:
//     Luminance value. Must be value between 0.0f and 100.0f.
public ColorHSL(float hue, float saturation, float luminance);

Thanks so much Greenya! It works perfect.

I change the value of this line
new IrrlichtLime.Video.ColorHSL(use,100,50);
and i get excatly what i want!
