drawstring

问题 Good morning. I have created a custom treeview control that paints a normal treeview onto the screen, plus various other things. During the paint event I draw the node.text string to the treeview control using the following method. node.text = "ABCDEFG" g.DrawString(node.Text, tvFont, Brushes.Black, strPosX + 10, bothPosY) Basically what I am trying to do is make part of the node.text italic, so that it renders on screen like so... AB*CDE*FG Personally I would approach this in such a way that

问题 I have created a new Bitmap object and now want do draw some text to it using GDI+. So I call Graphics.DrawString(...). The problem is that the size of the string depends on Windows 7's DPI settings. Is there any way to make my text drawing independent of the windows settings? PS: The DPI settings seem to affect text only. A rect for example stys the same size when changing the DPI... 回答1: Just found the solution myself: The key is to create the font with the parameter GraphicsUnit.Pixel.

问题 Let's say I have 200 pixels of space and I want to draw two strings into it: - the first string should be left justified - right second string should be right justified - But not overlap if they do not both fit (then do whatever my String.Trimming options say) Am I going to have to measure each and draw this manually, or does DrawString have some way to support what I'm trying to do without me reinventing the wheel? Imagine that \l and \r were escapes that did this, then I could say graphics

问题 I try to draw a string (single character) in C# into a Bitmap at an exact position with: Bitmap bmp = new Bitmap(64, 64); Graphics g = Graphics.FromImage(bmp); g.DrawString("W", font1, new SolidBrush(myColor), new Point(32,32); There is so much empty space rendered around a single letter, that I can not guess the "needed" position to draw the character to have it at the correct position at the end. By now I have the pixel exact dimension of the character (looking at bits in a separately

问题 I have tried all of the suggested ways to center text, but I can't seem to get the results I want while centering an individual character. I have a rectangle. In that rectangle I'm drawing a circle with DrawEllipse. Now I want to draw a single character inside the circle using the same rectangle and DrawString, to have it perfectly centered. Here is my basic code: StringFormat stringFormat = new StringFormat(); stringFormat.Alignment = StringAlignment.Center; stringFormat.LineAlignment =

问题 I'm using GDI+ in C++. (This issue might exist in C# too). I notice that whenever I call Graphics::MeasureString() or Graphics::DrawString(), the string is padded with blank space on the left and right. For example, if I am using a Courier font, (not italic!) and I measure "P" I get 90, but "PP" gives me 150. I would expect a monospace font to give exactly double the width for "PP". My question is: is this intended or documented behaviour, and how do I disable this? RectF Rect(0,0,32767,32767

问题 I am trying to visually center an arbitrary user-supplied string on a JPanel. I have read dozens of other similar questions and answers here on SO but haven't found any that directly address the problem I am having. In the code sample below, getWidth() and getHeight() refer to the width and height of the JPanel on which I'm placing the text string. I have found that TextLayout.getBounds() does a very good job of telling me the size of a bounding rectangle that encloses the text. So, I figured

问题 I'm trying to render some text into a specific part of an image in a Web Forms app. The text will be user entered, so I want to vary the font size to make sure it fits within the bounding box. I have code that was doing this fine on my proof-of-concept implementation, but I'm now trying it against the assets from the designer, which are larger, and I'm getting some odd results. I'm running the size calculation as follows: StringFormat fmt = new StringFormat(); fmt.Alignment = StringAlignment

问题 I want to draw the following text on panel: It is a multi-colored text. I found this article about drawing multicolored text. I replaced characters with words but it doesn't work. (I use FillPath/DrawPath to draw text) my code: private void Form1_Paint(object sender, PaintEventArgs e) { const string txt = "C# Helper! Draw some text with each letter in a random color."; // Make the font. using (Font the_font = new Font("Times New Roman", 40, FontStyle.Bold | FontStyle.Italic)) { // Make a
