Detailed Description

The QTextImageFormat class provides formatting information for images in a QTextDocument.

Inline images are represented by an object replacement character (0xFFFC in Unicode) 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.

See also QImage and QImageReader.
