I am using the graphics.MeasureString method to measure the text size. And based on the measured text size, I was the draw the string using the graphics.MeasureString. But in that I was using the StringFormat to measure and draw the string. But I found the text clipping problem in some text like "left".
Please find the code snippet below,
string text = "Left";
Font font = new System.Drawing.Font("Segoe UI Semibold", 9F);
StringFormat format = new StringFormat(StringFormatFlags.NoWrap);
SizeF size = e.Graphics.MeasureString(text, font, 100, format);
e.Graphics.DrawString(text, font, new SolidBrush(Color.Black), new RectangleF(10, 10, size.Width, size.Height), format);
Please find the text clipping while drawing in below screen shot,
Can you please suggest how to solve this issue?
Try the following. I have removed the StringFormat from the code. It works.
string text = "Left";
Font font = new Font("Segoe UI Semibold", 9F);
//StringFormat format = new StringFormat(StringFormatFlags.NoWrap);
SizeF size = e.Graphics.MeasureString(text, font, 100);
e.Graphics.DrawString(text, font, new SolidBrush(Color.Black), new RectangleF(10, 10, size.Width, size.Height));
Edit1
I have modified the answer as per OP's request to use StringFormat enum.
string text = "Left";
Font font = new Font("Segoe UI Semibold", 9F);
StringFormat format = new StringFormat(StringFormatFlags.NoWrap);
SizeF size = e.Graphics.MeasureString(text, font, 100, format);
e.Graphics.DrawString(text, font, new SolidBrush(Color.Black), new RectangleF(10, 10, size.Width + 5, size.Height), format);

I have never worked with drawing before and im having a little issue. I cant seem to get the output of this code to work.
The file is saving but it is not drawing on the text. Can anyone see what i may have done wrong?
EDIT: A silly mistake - the backgrond of the image was white (and the brush colour was!). The text is not centered however as i would have expected. Any ideas why SO? :)
EDIT: Image is below.
Thanks
Bitmap myBitmap = new Bitmap(#"C:\Users\Scott\desktop\blank.bmp");
Graphics g = Graphics.FromImage(myBitmap);
g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAlias;
g.DrawString("My\nText",
new Font("Tahoma", 20),
Brushes.White,
new PointF(0, 0));
StringFormat strFormat = new StringFormat();
strFormat.Alignment = StringAlignment.Center;
strFormat.LineAlignment = StringAlignment.Center;
g.DrawString("My\nText",
new Font("Tahoma", 20), Brushes.White,
new RectangleF(0, 0, 500, 500),
strFormat);
myBitmap.Save(#"C:\Users\Scott\desktop\blank1.bmp");
I am sure you might be looking for this.
rectf = new RectangleF(655, 460, 535, 90); //rectf for My Text
using(Graphics g = Graphics.FromImage(myBitmap))
{
//g.DrawRectangle(new Pen(Color.Red, 2), 655, 460, 535, 90);
g.SmoothingMode = SmoothingMode.AntiAlias;
g.InterpolationMode = InterpolationMode.HighQualityBicubic;
g.PixelOffsetMode = PixelOffsetMode.HighQuality;
StringFormat sf = new StringFormat();
sf.Alignment = StringAlignment.Center;
sf.LineAlignment = StringAlignment.Center;
g.DrawString("My\nText", new System.Drawing.Font("Tahoma", 32, FontStyle.Bold), Brushes.Black, rectf, sf);
}
//g.DrawRectangle(new Pen(Color.Red, 2), 655, 460, 535, 90); Line is used to show where your text will be written. So before you actually make your make your text You can see where this rectanlge will be created on the image. If you want the center of the image you can find the height and width and divide that by 2 to find the center of the image and than can plot the rectangle parameters accordingly.
I'm trying to draw a box around a label which has been aligned using StringAlignment.Far for example. I can find the Size of text using g.MeasureString but I can't find a method to translate the origin point such that I can find a Rectangle which bounds the text.
Say I have a Point origin at which to draw from, and a StringFormat format with what alignment I wish my string to have. I can find the Size of the string using g.MeasureString(text, font). How do I translate this Point/Size pair into a rectangle which overlaps the g.DrawString(text, font, brush, origin, format) call.
It's difficult to convert c to managed code. You should use .Net code directly if it's available.
For MeasureString, see link Graphics.MeasureString Method
Example:
using System.Diagnostics;
...
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
Graphics g = e.Graphics;
Font font = new Font("Arial", 16);
SizeF sz = g.MeasureString("Text...", font);
Rectangle rc = new Rectangle(0,0, (int)sz.Width, (int)sz.Height);
Debug.WriteLine(rc.Width.ToString());
Debug.WriteLine(rc.Height.ToString());
//change top/left origin of rectangle
rc.X = 10;
rc.Y = 20;
}
You just need the width and height of text. You can change left/top corner of rectangle.
By the way, the C method gives a rectangle with top/left coordinates at zero, so it's the same information as Size
Edit
This will fit text with word-break flag in to a rectangle whose width is 100. The height of the rectangle is not known. TextRenderer.MeasureText will tell us the height of the rectangle. Top/left corner can be changed, alignment can be changed.
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
Font font = new Font("Arial", 10);
string text = "I'm trying to draw a box around a label which has been aligned.";
Size layout = new Size(100, 0);
Size sz = TextRenderer.MeasureText(e.Graphics, text, font, layout,
TextFormatFlags.WordBreak);
Rectangle rc = new Rectangle(new Point(0,0), sz);
e.Graphics.DrawRectangle(Pens.Black, rc);
TextRenderer.DrawText(e.Graphics, text, font, rc,
SystemColors.ControlText, SystemColors.Control, TextFormatFlags.WordBreak);
}
My way is use SetMeasurableCharacterRanges to obtain the region of the whole text.
Consider into OnPaint:
protected override void OnPaint(PaintEventArgs e)
{
Graphics g = e.Graphics;
Font font = new Font("Arial", 16);
string text = "Border of this text";
StringFormat sf = new StringFormat();
sf.Alignment = StringAlignment.Center;
sf.LineAlignment = StringAlignment.Center;
RectangleF area = new RectangleF(0, 0, 246, 84);
sf.SetMeasurableCharacterRanges(new CharacterRange[] { new CharacterRange(0, text.Length) });
Region[] r = g.MeasureCharacterRanges(text, font, area, sf);
Rectangle rf = new Rectangle((int)r[0].GetBounds(g).X, (int)r[0].GetBounds(g).Y, (int)r[0].GetBounds(g).Width, (int)r[0].GetBounds(g).Height);
g.DrawString(text, font, Brushes.Black, area, sf);
g.DrawRectangle(new Pen(Color.Red, 1), rf);
}
I want to align the dynamic text on my progress bar.
Here is the code
using (var sf = new StringFormat()
{
Alignment = StringAlignment.Center,
LineAlignment = StringAlignment.Center,
}
)
progressBar1.CreateGraphics()
.DrawString(message, new Font("Arial", (float)8.25, FontStyle.Regular), Brushes.Black, new Rectangle(0, 0, 600, 480), sf);
The values 600,480 is the size of my application.
My progress bar location is 0,430
Progress bar dimensions are 600,11
Can anyone please help me?
using (var sf = new StringFormat()
{
Alignment = StringAlignment.Center,
LineAlignment = StringAlignment.Center,
})
{
progressBar1.CreateGraphics()
.DrawString(message,
new Font("Arial",
(float) 20, FontStyle.Regular),
Brushes.Black,
new Rectangle(0, 0, 600, 480), sf);
}
Use this to measure the size of the string: Graphics.MeasureString
Then use this simple formula:
containerWidth // width in pixels of the container
textWidth // width of your string in pixels
margin = (containerWidth - textWidth) / 2;
You must offset the text from the left by margin pixels.
This is the output i get when i use DrawString.

page is a float datatype which value is based on e.PageSettings.Margins.Left;
e.Graphics.DrawString(Text, new System.Drawing.Font("Arial", 8F, FontStyle.Regular), Brushes.Black, page, 30);
In the above example, it is
e.Graphics.DrawString(Text, new System.Drawing.Font("Arial", 8F, FontStyle.Regular), Brushes.Black, page, 30);
I tried using this
StringFormat format = new StringFormat();
format.FormatFlags = StringFormatFlags.FitBlackBox;
e.Graphics.DrawString(Text, new System.Drawing.Font("Arial", 8F, FontStyle.Regular), Brushes.Black, page, 30, format);
How do i expand/word wrap so that i can have the entire words instead of '...' at the end?

You can "word wrap" the text by using a bounding rectangle.
Use Graphics.DrawString Method (String, Font, Brush, RectangleF, StringFormat)
The RectangleF specifies the draw area and it will automatically "wrap" your text for you.
I would like to draw some text in a rectangle and have it scale to the maximum size that fits within the rectangle.
So far I have this:
Bitmap bitmapImage = new Bitmap(500, 500);
Graphics graphicImage = Graphics.FromImage(bitmapImage);
graphicImage.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
var rect = new Rectangle(0, 0, 500, 500);
graphicImage.DrawString( "testing testing 123!", new Font("Arial", 12, FontStyle.Bold), Brushes.Black, rect);
bitmapImage.Save("test.png");
it draws the text but doesn't scale up the font size.
Call Graphics.MeasureString in a binary search loop.
