The following class members are obsolete. They are provided to keep old source code working. We strongly advise against using them in new code.
Returns a number that identifies the contents of this QImage object. Distinct QImage objects can only have the same serial number if they refer to the same contents (but they don't have to).
Use cacheKey() instead.
Warning: The serial number doesn't necessarily change when the image is altered. This means that it may be dangerous to use it as a cache key.
See also operator==().
Sets the alpha channel of this image to the given alphaChannel.
If alphaChannel is an 8 bit grayscale image, the intensity values are written into this buffer directly. Otherwise, alphaChannel is converted to 32 bit and the intensity of the RGB pixel values is used.
Note that the image will be converted to the Format_ARGB32_Premultiplied format if the function succeeds.
Use one of the composition mods in QPainter::CompositionMode instead.
See also alphaChannel(), Image Transformations, and Image Formats.
Sets the image text to the given text and associate it with the given key. The text is recorded in the specified language, or in a default language if language is 0.
Use setText() instead.
The language the text is recorded in is no longer relevant since the text is always set using QString and UTF-8 representation.
Returns the text recorded for the given key in the given language, or in a default language if language is 0.
Use text() instead.
The language the text is recorded in is no longer relevant since the text is always set using QString and UTF-8 representation.
This is an overloaded member function, provided for convenience.
Returns the text recorded for the given keywordAndLanguage.
Use text() instead.
The language the text is recorded in is no longer relevant since the text is always set using QString and UTF-8 representation.
Returns the language identifiers for which some texts are recorded. Note that if you want to iterate over the list, you should iterate over a copy.
The language the text is recorded in is no longer relevant since the text is always set using QString and UTF-8 representation.
Returns a list of QImageTextKeyLang objects that enumerate all the texts key/language pairs set for this image.
Use textKeys() instead.
The language the text is recorded in is no longer relevant since the text is always set using QString and UTF-8 representation.
