NAME

       QPNGImagePacker - Creates well-compressed PNG animations

SYNOPSIS

       #include <qpngio.h>

   Public Members
       QPNGImagePacker ( QIODevice * iod, int storage_depth, int conversionflags )
       void setPixelAlignment ( int x )
       bool packImage ( const QImage & img )

DESCRIPTION

       The QPNGImagePacker class creates well-compressed PNG animations.

       By using transparency, QPNGImagePacker allows you to build a PNG image from a sequence of QImages.

       Images are added using packImage().

       See also Graphics Classes and Image Processing Classes.

MEMBER FUNCTION DOCUMENTATION

QPNGImagePacker::QPNGImagePacker ( QIODevice * iod, int storage_depth, int conversionflags )
       Creates an image packer that writes PNG data to IO device iod using a storage_depth bit encoding (use 8 or 32, depending on the desired
       quality and compression requirements).

       If the image needs to be modified to fit in a lower-resolution result (e.g. converting from 32-bit to 8-bit), use the conversionflags to
       specify how you'd prefer this to happen.

       See also Qt::ImageConversionFlags.

bool QPNGImagePacker::packImage ( const QImage & img )
       Adds the image img to the PNG animation, analyzing the differences between this and the previous image to improve compression.

void QPNGImagePacker::setPixelAlignment ( int x )
       Aligns pixel differences to x pixels. For example, using 8 can improve playback on certain hardware. Normally the default of 1-pixel
       alignment (i.e. no alignment) gives better compression and performance.

NAME

       QHideEvent - Event which is sent after a widget is hidden

SYNOPSIS

       #include <qevent.h>

       Inherits QEvent.

   Public Members
       QHideEvent ()

DESCRIPTION

       The QHideEvent class provides an event which is sent after a widget is hidden.

       This event is sent just before QWidget::hide() returns, and also when a top-level window has been hidden (iconified) by the user.

       If spontaneous() is TRUE the event originated outside the application, i.e. the user hid the window using the window manager controls,
       either by iconifying the window or by switching to another virtual desktop where the window isn't visible. The window will become hidden
       but not withdrawn. If the window was iconified, QWidget::isMinimized() returns TRUE.

       See also QShowEvent and Event Classes.

MEMBER FUNCTION DOCUMENTATION

QHideEvent::QHideEvent ()
       Constructs a QHideEvent.
