|
|---|
| 50 |
|
|---|
| 51 |
|
|---|
| 52 | The QCanvasPixmap class provides pixmaps for QCanvasSprites.
|
|---|
| 53 |
|
|---|
| 54 | <p>
|
|---|
| 55 |
|
|---|
| 56 |
|
|---|
| 57 | <p> If you want to show a single pixmap on a <a href="qcanvas.html">QCanvas</a> use a
|
|---|
| 58 | <a href="qcanvassprite.html">QCanvasSprite</a> with just one pixmap.
|
|---|
| 59 | <p> When pixmaps are inserted into a <a href="qcanvaspixmaparray.html">QCanvasPixmapArray</a> they are held
|
|---|
| 60 | as QCanvasPixmaps. <a href="qcanvassprite.html">QCanvasSprite</a>s are used to show pixmaps on
|
|---|
| 61 | <a href="qcanvas.html">QCanvas</a>es and hold their pixmaps in a QCanvasPixmapArray. If
|
|---|
| 62 | you retrieve a frame (pixmap) from a QCanvasSprite it will be
|
|---|
| 63 | returned as a QCanvasPixmap.
|
|---|
| 64 | <p> The pixmap is a <a href="qpixmap.html">QPixmap</a> and can only be set in the constructor.
|
|---|
| 65 | There are three different constructors, one taking a QPixmap, one
|
|---|
| 66 | a <a href="qimage.html">QImage</a> and one a file name that refers to a file in any
|
|---|
| 67 | supported file format (see <a href="qimageio.html">QImageIO</a>).
|
|---|
| 68 | <p> QCanvasPixmap can have a hotspot which is defined in terms of an (x,
|
|---|
| 69 | y) offset. When you create a QCanvasPixmap from a PNG file or from
|
|---|
| 70 | a QImage that has a <a href="qimage.html#offset">QImage::offset</a>(), the offset() is initialized
|
|---|
| 71 | appropriately, otherwise the constructor leaves it at (0, 0). You
|
|---|
| 72 | can set it later using <a href="#setOffset">setOffset</a>(). When the QCanvasPixmap is used
|
|---|
| 73 | in a <a href="qcanvassprite.html">QCanvasSprite</a>, the offset position is the point at
|
|---|
| 74 | <a href="qcanvasitem.html#x">QCanvasItem::x</a>() and <a href="qcanvasitem.html#y">QCanvasItem::y</a>(), not the top-left corner of
|
|---|
| 75 | the pixmap.
|
|---|
| 76 | <p> Note that for QCanvasPixmap objects created by a QCanvasSprite, the
|
|---|
| 77 | position of each QCanvasPixmap object is set so that the hotspot
|
|---|
| 78 | stays in the same position.
|
|---|
| 79 | <p> <p>See also <a href="qcanvaspixmaparray.html">QCanvasPixmapArray</a>, <a href="qcanvasitem.html">QCanvasItem</a>, <a href="qcanvassprite.html">QCanvasSprite</a>, <a href="graphics.html">Graphics Classes</a>, and <a href="images.html">Image Processing Classes</a>.
