C# Center the text in progress bar - c#

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.

How to Write Text On a Image with Centered Position C#

How can i change the position of the "hello and test" string in the green box to the center position in an image ? I want to place the position of the hello string and the test in the middle of an image (which I marked the red circle), the link to the image> https://cdn.pbrd.co/images/I1hTWNS.png
I have added a "center" alignment but the position of the string is still to the left of the image.
public void drawString()
{
string firstText = "Hello" + Environment.NewLine + "Test";
string imageFilePath = directory + name + "\\Desktop\\plain.jpg";
Bitmap newBitmap;
using (var bitmap = (Bitmap)Image.FromFile(imageFilePath))//load the image file
{
using (Graphics graphics = Graphics.FromImage(bitmap))
{
using (Font arialFont = new Font("Arial", 26, FontStyle.Bold, GraphicsUnit.Point))
{
Rectangle rect = new Rectangle(0, 0, ClientSize.Width - 10, ClientSize.Height - 10);
StringFormat sf = new StringFormat();
sf.LineAlignment = StringAlignment.Center;
sf.Alignment = StringAlignment.Center;
graphics.DrawString(firstText, arialFont, Brushes.Red, rect, sf);
graphics.DrawRectangle(Pens.Green, rect);
}
}
newBitmap = new Bitmap(bitmap);
}
newBitmap.Save(imageFilePath);//save the image file
newBitmap.Dispose();
}
I have added a "center" alignment but the position of the string is still to the left of the image.
You text is indeed centered in the rectangle you created. The problem is that the rectangle you based it off the ClientSize Height and Width which come from the control you are inside.
What you want to use is the current Bitmap properties for Height and Width.
instead of :
Rectangle rect = new Rectangle(0, 0, ClientSize.Width - 10, ClientSize.Height - 10);
you want :
Rectangle rect = new Rectangle(0, 0, bitmap.Width, bitmap.Height);

Text getting clipped when drawing using graphics.DrawString method

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);

Vertical Tab Control with horizontal text in Winforms

I would like to have the tabs on my TabControl displayed on the left, or sometimes right.
Unlike the System.Windows.Forms.TabControl, however, I would like the text to remain horizontal instead of being rotated by 90 or 270 degrees to the horizontal.
Here are a couple of pictures illustrating the concept
Though I could write code to do this myself in about an hour or two, I just thought I'd ask first if there is any existing Winforms control that implements such feature.
NB: Any existing solution should preferably be non-commercial.
Thanks.
I don't know how robust this is and I can't claim to have created it but...
http://www.dreamincode.net/forums/topic/125792-how-to-make-vertical-tabs/
Here's a way of doing it.
So first we are going to change its alignment to Left, by setting the property:
Alignment = Left
If you have XP themes turned on then you may notice the weird layout of Tab Control. Don't worry we will make it fine.
As you may have noticed that Tabs are vertical, and our requirement is horizontal. So we can change the size of Tabs. But before we can do this we have to set the SizeMode property as,
SizeMode = Fixed
Now we can change the size by using the ItemSize property,
ItemSize = 30, 120
Width = 30 and Height = 120
After setting the Alignment = Left, Tab control rotates the Tabs which causes the Width and Height seem to be reversed. That is why when we increase Height, we see that width is increasing and when we increase width the height is effected.
Now Text will also be displaying, but vertically. Unfortunately there is no simple way to resolve this issue. For this purpose we have to write the Text by ourselves. To do this we will first set the DrawMode
DrawMode = OwnerDrawFixed
01
Private Sub TabControl1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles TabControl1.DrawItem
Dim g As Graphics
Dim sText As String
Dim iX As Integer
Dim iY As Integer
Dim sizeText As SizeF
Dim ctlTab As TabControl
ctlTab = CType(sender, TabControl)
g = e.Graphics
sText = ctlTab.TabPages(e.Index).Text
sizeText = g.MeasureString(sText, ctlTab.Font)
iX = e.Bounds.Left + 6
iY = e.Bounds.Top + (e.Bounds.Height - sizeText.Height) / 2
g.DrawString(sText, ctlTab.Font, Brushes.Black, iX, iY)
End Sub

This is an old question but I found a good looking C# class. After adding the normal WinForms tab control. Add this to your project as a class E.G DotNetBarTabControl.cs Then make sure to replace the Winforms tab controls to this class.
this.tabControl1 = new System.Windows.Forms.TabControl();
must be changed to:
this.tabControl1 = new TabControls.DotNetBarTabControl();
private System.Windows.Forms.TabControl tabControl1;
must be changed to:
private TabControls.DotNetBarTabControl tabControl1;

You can have fun making a dark theme to. In the photo Form2 uses the material skin. It can be found on NuGet as well.
I have decided to share the code I developed since some people, such as Amit Andharia, would like to benefit from it.
This is the result after I had implemented Rob P.'s answer.
Release Notes:
Full design time support
Automatic resizing of tabs (up to 128px wide)
Tab icons implemented
Unused properties have been hidden
The code can be downloaded from here.
There is a tutorial provided by Microsoft for doing this with the existing TabControl on MSDN, with sample code given in both C# and Visual Basic .NET. Their method is based on using owner drawing. Summarizing their steps below:
Set the TabControl's Alignment property to Right.
Ensure all tabs are the same horizontal width by setting the SizeMode property to Fixed.
Set the ItemSize property to your preferred size for the tabs, keeping in mind that the width and height are reversed.
Set the DrawMode property to OwnerDrawFixed.
Set up an event handler for the TabControl's DrawItem event, and place your owner drawing code in there dictating how each tab should be displayed. Their C# sample code for the event handler is reproduced below for convenience (it assumes your TabControl is named tabControl1:
private void tabControl1_DrawItem(Object sender, System.Windows.Forms.DrawItemEventArgs e)
{
Graphics g = e.Graphics;
Brush _textBrush;
// Get the item from the collection.
TabPage _tabPage = tabControl1.TabPages[e.Index];
// Get the real bounds for the tab rectangle.
Rectangle _tabBounds = tabControl1.GetTabRect(e.Index);
if (e.State == DrawItemState.Selected)
{
// Draw a different background color, and don't paint a focus rectangle.
_textBrush = new SolidBrush(Color.Red);
g.FillRectangle(Brushes.Gray, e.Bounds);
}
else
{
_textBrush = new System.Drawing.SolidBrush(e.ForeColor);
e.DrawBackground();
}
// Use our own font.
Font _tabFont = new Font("Arial", (float)10.0, FontStyle.Bold, GraphicsUnit.Pixel);
// Draw string. Center the text.
StringFormat _stringFlags = new StringFormat();
_stringFlags.Alignment = StringAlignment.Center;
_stringFlags.LineAlignment = StringAlignment.Center;
g.DrawString(_tabPage.Text, _tabFont, _textBrush, _tabBounds, new StringFormat(_stringFlags));
}
You can probably experiment with your ItemSize property and the _tabFont value from the above code to fine-tune your tabs' appearance to whatever you need. For even fancier styling, I'd recommend looking at this other MSDN article as a starting point.

How to scale text when drawing to an Image with c#

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.

How to draw centered text onto a jpg using system.drawing in c#

I am using the following code to draw text onto a jpg image but it requires x/y coordinate percision on where to place the text.
var bmp = new Bitmap("C:\\testing\\Given.jpg");
var gra = Graphics.FromImage(bmp);
var text = "The Berman's";
var font = new Font("Segoe Script", 24);
var brush = Brushes.Orange;
var point = new PointF(130, 224);
gra.DrawString(text, font, brush, point);
bmp.Save("C:\\testing\\Custom.jpg");
How would I go about centering text onto an image? I am guessing it would have to do with defining some sort of container (rectangle maybe?) that is the width of the image and centering the text within that? Not sure what the best practice would be for this.
using(var sf = new StringFormat()
{
Alignment = StringAlignment.Center,
LineAlignment = StringAlignment.Center,
})
{
gra.DrawString(text, font, brush, new Rectangle(0, 0, bmp.Width, bmp.Height), sf);
}
