.SH DESCRIPTION
|
|
The QCanvasPixmap class provides pixmaps for QCanvasSprites.
|
|
.PP
|
|
If you want to show a single pixmap on a QCanvas use a QCanvasSprite with just one pixmap.
|
|
.PP
|
|
When pixmaps are inserted into a QCanvasPixmapArray they are held as QCanvasPixmaps. QCanvasSprites are used to show pixmaps on QCanvases and hold their pixmaps in a QCanvasPixmapArray. If you retrieve a frame (pixmap) from a QCanvasSprite it will be returned as a QCanvasPixmap.
|
|
.PP
|
|
The pixmap is a QPixmap and can only be set in the constructor. There are three different constructors, one taking a QPixmap, one a QImage and one a file name that refers to a file in any supported file format (see QImageIO).
|
|
.PP
|
|
QCanvasPixmap can have a hotspot which is defined in terms of an (x, y) offset. When you create a QCanvasPixmap from a PNG file or from a QImage that has a QImage::offset(), the offset() is initialized appropriately, otherwise the constructor leaves it at (0, 0). You can set it later using setOffset(). When the QCanvasPixmap is used in a QCanvasSprite, the offset position is the point at QCanvasItem::x() and QCanvasItem::y(), not the top-left corner of the pixmap.
|
|
.PP
|
|
Note that for QCanvasPixmap objects created by a QCanvasSprite, the position of each QCanvasPixmap object is set so that the hotspot stays in the same position.
|
|
.PP
|
|

.SH MEMBER FUNCTION DOCUMENTATION
|
|
.SH "QCanvasPixmap::QCanvasPixmap ( const QString & datafilename )"
|
|
Constructs a QCanvasPixmap that uses the image stored in \fIdatafilename\fR.
|
|
.SH "QCanvasPixmap::QCanvasPixmap ( const QImage & image )"
|
|
Constructs a QCanvasPixmap from the image \fIimage\fR.
|
|
.SH "QCanvasPixmap::QCanvasPixmap ( const QPixmap & pm, const QPoint & offset )"
|
|
Constructs a QCanvasPixmap from the pixmap \fIpm\fR using the offset \fIoffset\fR.
|
|
.SH "QCanvasPixmap::~QCanvasPixmap ()"
|
|
Destroys the pixmap.
|
|
.SH "int QCanvasPixmap::offsetX () const"
|
|
Returns the x-offset of the pixmap's hotspot.
|
|
.PP
|
|
See also setOffset().
|
|
.SH "int QCanvasPixmap::offsetY () const"
|
|
Returns the y-offset of the pixmap's hotspot.
|
|
.PP
|
|
See also setOffset().
|
|
.SH "void QCanvasPixmap::setOffset ( int x, int y )"
|
|
Sets the offset of the pixmap's hotspot to (\fIx\fR, \fIy\fR).
|
|
.PP
|
|
\fBWarning:\fR Do not call this function if any QCanvasSprites are
|
|
currently showing this pixmap.
