How to add vertical lines in a processed image???
May 24 2010 4:48 AM
Hi to everyone,
Congratulation for the great job in this forum.
From previous topic I attained to process an image and have a new size.
In my application(in Extract Image field,see the screen below), i want again to load in a pictureBox (pictureBox4) the resized image-photo from previous pictureBox (pictureBox3) and add crosses(i mean vertical and horizontal lines) but in parallel, to fill the lost space from the previous resized image-photo.
I have already achieved to add horizontal lines but no vertical lines...in my application.
This is the code for horizontal lines:
private void btnAddCrosses_Click(object sender, EventArgs e)
{ //take the resized photo
Image source = pictureBox4.Image;
Bitmap sbitmap = new Bitmap(source);
int height, width, f_width, f_height ;
height = source.Height ;
width = source.Width;
//Define the steps(pixels) you want in the textBox
int step = Convert.ToInt32(textBox2.Text);
//Resizing photo to the first size
f_width = width + System.Convert.ToInt32(Math.Floor((double)(width / step ))) - 1;
f_height = height + System.Convert.ToInt32(Math.Floor((double)(height / step))) - 1;
Bitmap myBitmap = new Bitmap(f_width,f_height);
int xadd, yadd;
xadd = 0;
yadd = 0;
Color scolor;
for (int x = 0; x < width; x++ )
{
xadd = 0;
yadd = 0;
for (int y = 0; y < height; y++)
{
if (y % step == 0)
{
yadd++;
myBitmap.SetPixel(x+xadd , y+yadd, Color.White);
}
else
{
scolor = sbitmap.GetPixel(x, y);
myBitmap.SetPixel(x, y, scolor);
}
}
}
pictureBox5.Image = myBitmap;
}
Also i can provide you with a screenshot of my application, so you can see better what exactly i mean:
