Mixing
Drawing and Saving an Image
0
I am in the process of developing an app that will be later integrated with another app I developed some time ago.
Basically, this app will generate an image file of X and Y dimensions with a grid printed on it, of which the user also specifies it's interval.
I've done this form so far, but I am having difficulty deciding what the best way to generate an actual image with the proper dimensions and grid spacing should be.
I don't want to save the image that is displayed on the form because it is only a representation and could very well be extremely dissimilar from the final product.
So I guess my question is, what do you think the best way is to generate a black and white image when I click "save"?
Also, I have no need to see the image being saved, I just want to generate and save it behind the scenes.
Here is the "draw" button click event
private void btnDraw_Click(object sender, EventArgs e)
{
this.Width = 560;
using (g = pb.CreateGraphics())
{
g.Clear(Color.White);
PaintCanvass canvass = new PaintCanvass();
canvass.Width = Convert.ToDouble(tbWidth.Text);
canvass.Height = Convert.ToDouble(tbHeight.Text);
canvass.Resolution = Convert.ToInt32(cbResolution.Text.Substring(0,3));
canvass.UOM = cbUOM.Text;
canvass.Interval = Convert.ToInt32(tbInterval.Text);
Pen pencil = new Pen(Color.Black, 2);
int hpfact = Convert.ToInt32((double)pb.Height / (double)canvass.horizontalLinesQuantity);
int hp = hpfact;
for (int i = 0; i < canvass.horizontalLinesQuantity-1; i++)
{
g.DrawLine(pencil, new Point(0, hp), new Point(pb.Width, hp));
hp = hp + hpfact;
}
int vpfact = Convert.ToInt32((double)pb.Width / (double)canvass.verticalLinesQuantity);
int vp = vpfact;
for (int i = 0; i < canvass.verticalLinesQuantity-1; i++)
{
g.DrawLine(pencil, new Point(vp, 0), new Point(vp, pb.Height));
vp = vp + vpfact;
}
canvass = null;
And here is my PaintCanvass class which seems to just be ending up as a container for properties for now
class PaintCanvass
{
public double Width { get; set; }
public double Height { get; set; }
public string UOM { get; set; }
public int Resolution { get; set; }
public int Interval { get; set; } = 50;
public int hdots
{
get
{
if (this.UOM == "mm")
{
return Convert.ToInt32(Width * 0.03937008F * Resolution);
}
else
{
return Convert.ToInt32(Width * Resolution);
};
}
}
public int vdots
{
get
{
// Set the quantity of lines
if (this.UOM == "mm")
{
return Convert.ToInt32(Height * 0.03937008F * Resolution);
}
else
{
return Convert.ToInt32(Height * Resolution);
};
}
}
public int horizontalLinesQuantity
{
get
{
return vdots / this.Interval;
}
}
public int verticalLinesQuantity
{
get
{
return hdots / this.Interval;
}
}
}
Edit: as suggested I went with the bitmap method.
private void btnSave_Click(object sender, EventArgs e)
{
SetupCanvass();
using (Bitmap bmp = new Bitmap(canvass.hdots, canvass.vdots))
{
using (Graphics g = Graphics.FromImage(bmp))
{
using (SolidBrush brush = new SolidBrush(Color.FromArgb(255, 255, 255)))
{
g.FillRectangle(brush, 0, 0, canvass.hdots, canvass.vdots);
}
int hp = canvass.Interval;
for (int i = 0; i < canvass.horizontalLinesQuantity - 1; i++)
{
g.DrawLine(pencil, new Point(0, hp), new Point(canvass.hdots, hp));
hp = hp + canvass.Interval;
}
int vp = canvass.Interval;
for (int i = 0; i < canvass.verticalLinesQuantity - 1; i++)
{
g.DrawLine(pencil, new Point(vp, 0), new Point(vp, canvass.vdots));
vp = vp + canvass.Interval;
}
}
bmp.Save(Path.Combine(Path.GetTempPath(), "labelGrid.png")); //Save image somwhere on disk
}
}

If you want to save an image without displaying a preview, just do something like this:
using (Bitmap bmp = new Bitmap(500, 500))
{
using (Graphics g = Graphics.FromImage(bmp))
{
//Draw your stuff directly onto the bitmap here
}
bmp.Save("C:\image.bmp"); //Save image somwhere on disk
}

Basically correct but a) better not save to the root and b) better pick a more reasonable format like jpg or png. Also I would recommend setting the dpiX/Y of the bitmap.

Basically correct but a) better not save to the root and b) better pick a more reasonable format like jpg or png. Also I would recommend setting the dpiX/Y of the bitmap.

If you want to save an image without displaying a preview, just do something like this:
using (Bitmap bmp = new Bitmap(500, 500))
{
using (Graphics g = Graphics.FromImage(bmp))
{
//Draw your stuff directly onto the bitmap here
}
bmp.Save("C:\image.bmp"); //Save image somwhere on disk
}

Why not generate a new Bitmap, display that one in the picturebox and then save the bitmap instance when clicking on the button? No need to draw on the canvas

@Icepickle As stated in the post "I don't want to save the image that is displayed on the form because it is only a representation and could very well be extremely dissimilar from the final product."
– Jaberwocky

Sure, I didn't suggest that either, I suggested you generate a bitmap instead of drawing to the canvas and save that bitmap, but as you till now display a preview, you could theoretically also show the bitmap in the picturebox (optionally)

@Icepickle Why don't you post some small example of what you mean as an answer? I am assuming you're saying to create a bitmap using the PictureBox.Image property?

No just use new
Bitmap( width, height, PixelFormat)and create graphics from that instance– Icepickle
