详细描述

The QTextImageFormat class provides formatting information for images in a 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() and 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.

参见 QImage and QImageReader.
