Практическое руководство. Создание графических объектов для рисования How to: Create Graphics Objects for Drawing

Прежде чем рисовать линии и фигуры, отображать текст или отображать изображения и управлять ими с помощью GDI+, необходимо создать Graphics объект. Before you can draw lines and shapes, render text, or display and manipulate images with GDI+, you need to create a Graphics object. GraphicsОбъект представляет поверхность рисования GDI+, а — объект, используемый для создания графических изображений. The Graphics object represents a GDI+ drawing surface, and is the object that is used to create graphical images.

Работа с графикой состоит из двух этапов. There are two steps in working with graphics:

Создание Graphics объекта. Creating a Graphics object.

Использование Graphics объекта для рисования линий и фигур, отображения текста или отображения изображений и управления ими. Using the Graphics object to draw lines and shapes, render text, or display and manipulate images.

Создание графического объекта Creating a Graphics Object

Графический объект может быть создан различными способами. A graphics object can be created in a variety of ways.

Создание графического объекта To create a graphics object

Получение ссылки на графический объект в составе PaintEventArgs Paint события формы или элемента управления. Receive a reference to a graphics object as part of the PaintEventArgs in the Paint event of a form or control. Обычно это способ получения ссылки на графический объект при создании кода рисования для элемента управления. This is usually how you obtain a reference to a graphics object when creating painting code for a control. Аналогично, объект Graphics можно также получить как свойство объекта PrintPageEventArgs при обработке PrintPage события для PrintDocument . Similarly, you can also obtain a graphics object as a property of the PrintPageEventArgs when handling the PrintPage event for a PrintDocument.

Вызовите CreateGraphics метод элемента управления или формы, чтобы получить ссылку на Graphics объект, представляющий поверхность рисования этого элемента управления или формы. Call the CreateGraphics method of a control or form to obtain a reference to a Graphics object that represents the drawing surface of that control or form. Используйте этот метод, если требуется рисовать на форме или элементе управления, который уже существует. Use this method if you want to draw on a form or control that already exists.

Создайте Graphics объект из любого объекта, наследующего от Image . Create a Graphics object from any object that inherits from Image. Этот подход удобен, если требуется изменить уже существующий образ. This approach is useful when you want to alter an already existing image.

Следующие разделы содержат сведения о каждом из этих процессов. The following sections give details about each of these processes.

PaintEventArgs в обработчике событий Paint PaintEventArgs in the Paint Event Handler

При программировании PaintEventHandler для элементов управления или PrintPage для PrintDocument объект Graphics предоставляется как одно из свойств PaintEventArgs или PrintPageEventArgs . When programming the PaintEventHandler for controls or the PrintPage for a PrintDocument, a graphics object is provided as one of the properties of PaintEventArgs or PrintPageEventArgs.

Получение ссылки на объект Graphics из PaintEventArgs в событии Paint To obtain a reference to a Graphics object from the PaintEventArgs in the Paint event

Объявите Graphics объект. Declare the Graphics object.

Назначьте переменную для ссылки на Graphics объект, передаваемый как часть PaintEventArgs . Assign the variable to refer to the Graphics object passed as part of the PaintEventArgs.

Вставка кода для заполнения формы или элемента управления. Insert code to paint the form or control.

В следующем примере показано, как ссылаться на Graphics объект из PaintEventArgs в Paint событии. The following example shows how to reference a Graphics object from the PaintEventArgs in the Paint event:

Метод CreateGraphics CreateGraphics Method

Можно также использовать CreateGraphics метод элемента управления или формы для получения ссылки на Graphics объект, представляющий поверхность рисования этого элемента управления или формы. You can also use the CreateGraphics method of a control or form to obtain a reference to a Graphics object that represents the drawing surface of that control or form.

Создание графического объекта с помощью метода CreateGraphics To create a Graphics object with the CreateGraphics method

Вызовите CreateGraphics метод формы или элемента управления, для которого требуется отобразить графические объекты. Call the CreateGraphics method of the form or control upon which you want to render graphics.

Создание из объекта Image Create from an Image Object

Кроме того, можно создать графический объект из любого объекта, производного от Image класса. Additionally, you can create a graphics object from any object that derives from the Image class.

Создание графического объекта из изображения To create a Graphics object from an Image

Вызовите Graphics.FromImage метод, указав имя переменной изображения, из которой нужно создать Graphics объект. Call the Graphics.FromImage method, supplying the name of the Image variable from which you want to create a Graphics object.

В следующем примере показано, как использовать Bitmap объект: The following example shows how to use a Bitmap object:

Создавать объекты можно только Graphics из неиндексированных BMP-файлов, таких как 16-разрядные, 24-разрядные и 32-битовые BMP. You can only create Graphics objects from nonindexed .bmp files, such as 16-bit, 24-bit, and 32-bit .bmp files. Каждый пиксель неиндексированных BMP-файлов содержит цвет, в отличие от пикселов индексированных BMP-файлов, которые содержат индекс для таблицы цветов. Each pixel of nonindexed .bmp files holds a color, in contrast to pixels of indexed .bmp files, which hold an index to a color table.

Рисование фигур и изображений и управление ими Drawing and Manipulating Shapes and Images

После создания Graphics объект может использоваться для рисования линий и фигур, отображения текста или отображения изображений и управления ими. After it is created, a Graphics object may be used to draw lines and shapes, render text, or display and manipulate images. Объекты Principal, используемые с Graphics объектом: The principal objects that are used with the Graphics object are:

PenКласс, используемый для рисования линий, структурирования фигур или визуализации других геометрических представлений. The Pen class—Used for drawing lines, outlining shapes, or rendering other geometric representations.

BrushКласс, используемый для заливки областей графических объектов, таких как заполненные фигуры, изображения или текст. The Brush class—Used for filling areas of graphics, such as filled shapes, images, or text.

FontКласс — содержит описание фигур, используемых при отрисовке текста. The Font class—Provides a description of what shapes to use when rendering text.

ColorСтруктура — представляет различные отображаемые цвета. The Color structure—Represents the different colors to display.

Использование созданного объекта Graphics To use the Graphics object you have created

Для рисования нужного объекта выполните действия с соответствующим объектом, приведенным выше. Work with the appropriate object listed above to draw what you need.

Примеры

В следующем примере кода показано использование PictureBox ListView элементов управления и. The following code example demonstrates the use of the PictureBox and ListView controls. PictureBoxИнициализируется путем задания BorderStyle SizeMode свойств и с помощью BorderStyle PictureBoxSizeMode перечислений и соответственно. The PictureBox is initialized by setting the BorderStyle and SizeMode properties using the BorderStyle and PictureBoxSizeMode enumerations, respectively. ListViewЗаполняется изображениями из каталога Sample Pictures. The ListView is populated with pictures from the Sample Pictures directory. ListView.GetItemAtМетод используется при обработке MouseDown события ListView элемента управления, чтобы определить, выбран ли элемент. The ListView.GetItemAt method is used when handling the MouseDown event of the ListView control to determine whether an item is selected. Если элемент выбран, обработчик событий отображает выбранный файл, устанавливая Image свойство. If an item is selected, the event handler displays the selected file by setting the Image property. В этом примере требуется, чтобы файлы JPG размещались в каталоге «C:\Documents and Settings\All Усерс\документс\ми рисунки \ образцы Pictures». The example requires that you have JPG files located in the C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures directory. Чтобы выполнить пример, вставьте код в форму и вызовите InitializePictureBox PopulateListView методы и в конструкторе формы или в Load методе обработки событий. To run the example, paste the code into a form and call the InitializePictureBox and PopulateListView methods in the form’s constructor or Load event-handling method. Убедитесь, что все события связаны с их методами обработки событий. Ensure all events are associated with their event-handling methods.

Комментарии

В следующей таблице представлены исходные значения свойств для экземпляра класса PictureBox. The following table shows initial property values for an instance of the PictureBox class.

Picture Box Class

Definition

Represents a Windows picture box control for displaying an image.

Examples

The following code example illustrates how you can set an image and resize the display area of the picture box. This example requires that ShowMyImage is called in an existing form, and that the System.Drawing namespace has been added to the source code for your form.

Remarks

Typically the PictureBox is used to display graphics from a bitmap, metafile, icon, JPEG, GIF, or PNG file.

Set the Image property to the Image you want to display, either at design time or at run time. You can alternatively specify the image by setting the ImageLocation property and load the image synchronously using the Load method or asynchronously using the LoadAsync method.

If you want to use the same image in multiple PictureBox controls, create a clone of the image for each PictureBox. Accessing the same image from multiple controls causes an exception to occur.

The SizeMode property, which is set to values in the PictureBoxSizeMode enumeration, controls the clipping and positioning of the image in the display area. You can change the size of the display area at run time with the ClientSize property.

By default, the PictureBox control is displayed by without any borders. You can provide a standard or three-dimensional border using the BorderStyle property to distinguish the picture box from the rest of the form, even if it contains no image. The PictureBox is not a selectable control, which means that it cannot receive input focus.
