Add(Image, int)

Inserts an image inline, which means that it is treated in the text like a single character. The image is inserted at the specified text input position.

textPosition

Specifies the text position at which the image is to be inserted. If -1 is specified, the image is inserted at the current input position.

Add(Image, HorizontalAlignment, int, ImageInsertionMode)

Inserts a new image which is anchored to the specified text position. It has the specified horizontal alignment and a textflow which is given through the insertionMode parameter. Anchored images are moved with the text. A file open dialog box is shown to get the image's file name and filter. To avoid opening the dialog box set the Image.FileName and the Image.FilterIndex properties of the specified Image object.

public bool Add(Image image, HorizontalAlignment alignment, int textPosition, ImageInsertionMode insertionMode);
ParameterDescription
image

Specifies the image to add.

alignment

Specifies the image's horizontal alignment. It can be one of the HorizontalAlignment values:

ValueMeaning
LeftThe image is left aligned, relative to the paragraph to which it is anchored.
RightThe image is right aligned, relative to the paragraph to which it is anchored.
CenteredThe image is centered, relative to the paragraph to which it is anchored.
JustifyThis value is not supported for images.
textPosition

insertionMode

Specifies how the text flow is handled. It can be one of the following values of the ImageInsertionMode enumeration:

ValueMeaning
