Qt 3 Support Members for QPixmap

The following class members are part of the Qt 3 support layer. They are provided to help you port old code to Qt 4. We advise against using them in new code.

• QPixmap class reference

• 9 public functions inherited from QPaintDevice

Member Type Documentation

enum QPixmap::ColorMode

This enum type defines the color modes that exist for converting QImage objects to QPixmap. It is provided here for compatibility with earlier versions of Qt.

Use Qt::ImageConversionFlags instead.

Member Function Documentation

QPixmap::QPixmap ( const QString & fileName, const char * format, ColorMode mode )

Use the constructor that takes a Qt::ImageConversionFlag instead.

QPixmap::QPixmap ( const QImage & image )

Constructs a pixmap from the QImage image.

Use the static fromImage() function instead.

bool QPixmap::convertFromImage ( const QImage & image, ColorMode mode )

Use the static fromImage() function instead.

bool QPixmap::convertFromImage ( const QImage & image, Qt::ImageConversionFlags flags = Qt::AutoColor )

Use the static fromImage() function instead.

QImage QPixmap::convertToImage () const

Use the toImage() function instead.

bool QPixmap::load ( const QString & fileName, const char * format, ColorMode mode )

Use the load() function that takes a Qt::ImageConversionFlag instead.

bool QPixmap::loadFromData ( const uchar * buf, uint len, const char * format, ColorMode mode )

Use the loadFromData() function that takes a Qt::ImageConversionFlag instead.

void QPixmap::resize ( int width, int height )

Use QPixmap::copy() instead to get the pixmap with the new size.

For example, if you have code like

 pixmap.resize(10, 20);

you can rewrite it as

 pixmap = pixmap.copy(0, 0, 10, 20);

void QPixmap::resize ( const QSize & size )

This is an overloaded function.

Use QPixmap::copy() instead to get the pixmap with the new size.

For example, if you have code like

 pixmap.resize(size);

you can rewrite it as

 pixmap = pixmap.copy(QRect(QPoint(0, 0), size));

bool QPixmap::selfMask () const

Returns whether the pixmap is its own mask or not.

This function is no longer relevant since the concept of self masking doesn't exists anymore.

QPixmap QPixmap::xForm ( const QMatrix & matrix ) const

Use transformed() instead.

QPixmap::operator QImage () const

Returns the pixmap as a QImage.

Use the toImage() function instead.

QPixmap & QPixmap::operator= ( const QImage & image )

This is an overloaded function.

Converts the given image to a pixmap that is assigned to this pixmap.

Use the static fromImage() function instead.
