详细描述

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 using setWidth () 和 setHeight ().

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.
