The QTextImageFormat 类提供格式化信息为图像在 QTextDocument .
Inline images are represented by a Unicode value U+FFFC (OBJECT REPLACEMENT CHARACTER) which has an associated QTextImageFormat . The image format specifies a name with setName () that is used to locate the image. The size of the rectangle that the image will occupy is specified in pixels using setWidth () 和 setHeight (). The desired image quality may be set with setQuality ().
Images can be supplied in any format for which Qt has an image reader, so SVG drawings can be included alongside PNG, TIFF and other bitmap formats.
