Pen variable_name = new Pen ( color, width) A Pen object may be quite easily created as follows: Now that we have a Graphic Object we need a Pen with which to draw.Ī Graphics Object is of little use without a Pen object with which to draw (much as a sheet of paper is no good without a pen or pencil). For example, a Graphics Object can be created on our Form called Form1 by calling CreateGraphics() method as follows in the Paint() method: private void Form1_Paint(object sender, PaintEventArgs e) Graphics Objects are created by calling the CreateGraphics() method of the component on which the drawing is to performed.

Double click the Paint event to display the code editing page. With the new project created select the Form in the design area and click on the lightning bolt at the top of the Properties panel to list the events available for the Form. The first step in this tutorial is to create a new Visual Studio project called CSharpGraphics. We will look at redrawing the graphics in the Paint() event in this chapter and Using Bitmaps for Persistent Graphics in C# in the next chapter. One is to repeatedly perform the drawing in the Paint() event handler of the control (which is triggered whenever the component needs to be redrawn), or to perform the drawing on a bitmap image in memory and then transfer that image to the component whenever the Paint() event is triggered. Two mechanisms are available for achieving this. In fact what will happen is that as soon as the window is minimized or obscured by another window the graphics will be erased.įor this reason, steps need to be taken to ensure that any graphics are persistent. Custom colors and colors on the Standard tab aren't updated if you later change the document theme.An important point to note before proceeding with is chapter is that simply creating a Graphics Object for a component and then drawing on that component does not create persistent graphics. In the Colors box, either click the color that you want on the Standard tab, or mix your own color on the Custom tab. On the Drawing Tools Format tab, click Shape Outline, and then click More Outline Colors. To change the border to a color that isn't in the theme colors On the Drawing Tools Format tab, click Shape Outline and, under Theme Colors, pick the color you want. If you want to change multiple shapes or text boxes, click the first shape or text box, and then press and hold Ctrl while you click the other shapes or text boxes. On the Drawing Tools Format tab, click Shape Fill > More Fill Colors. To change the fill color to a color that isn't in the theme colors When you do that, the Drawing Tools appear.Ĭlick Shape Fill, and under Theme Colors, pick the color you want. Custom colors and colors on the Standard tab aren't updated if you later change the document theme.

Note: The Text Fill and Text Outline menus might not be active until you start typing in your shape. On the Drawing Tools Format tab, click Text Fill and, under Theme Colors, pick the color you want. To change multiple shapes or text boxes, click the first shape or text box, and then press and hold Ctrl while you click the other shapes or text boxes. When you do that, the Drawing Tools appear. We used the Shape Outline, Shape Fill, and Text Fill commands, available on the Format tab under Drawing Tools.Īlthough the changes we'll make below are shown in Microsoft PowerPoint, they work the same way in Excel, Word, Outlook, and Project. Here's the same shape after we changed the border to orange, the fill to a light green, and the text to black. Let's select the shape-the Drawing Tools appear in the ribbon, with the Format tab active. In a text box or shape, you can quickly change the color of text, the inside (fill) color, or the color of the border.
