I am trying to create an application that creates a mosaic of all of my Australia pictures, here is my first try -
Here is the code for it so far -
Image i,v,t,thumb;
//Bitmap b;
Graphics g,rg;
i=Image.FromFile(((imageFile)lstImages.Items[0]).FI.FullName);
double scale=i.Width/((int)nudWidth.Value);
v=new Bitmap(((int)nudWidth.Value)*((int)nudAcross.Value),
(lstImages.Items.Count/((int)nudAcross.Value))*(int)(i.Height/scale));
int x=0;
int y=0;
foreach(imageFile @if in lstImages.Items)
{
i=Image.FromFile(@if.FI.FullName);
if(i.Height>i.Width) i.RotateFlip(System.Drawing.RotateFlipType.Rotate90FlipNone);
thumb=new Bitmap((int)(i.Width/scale),(int)(i.Height/scale));
rg=Graphics.FromImage(thumb);
rg.InterpolationMode=System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
rg.DrawImage(i,new Rectangle(0,0,(int)(i.Width/scale),(int)(i.Height/scale)),
new Rectangle(0,0,i.Width,i.Height),GraphicsUnit.Pixel);
rg.Dispose();
g=Graphics.FromImage(v);
g.DrawImageUnscaled(thumb,x*(int)(i.Width/scale),y*(int)(i.Height/scale));
g.Dispose();
x++;
if(x-1==((int)nudAcross.Value))
{
x=0; y++;
}
}
v.Save(txtOutput.Text,System.Drawing.Imaging.ImageFormat.Jpeg);
