QTextImageFormat ¶

概要 ¶

详细描述 ¶

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() and 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.
