[4.2.2] Composing multiple images
Message 1 in thread
Hi there,
I've got a list of images which I'd like to 'compose' in a single big
one like this:
- - - - - - - - - - - - -
| Img | Img | Img | Img |
- - - - - - - - - - - - -
Is there a simple way of doing that? I can't find any convenience
methods ...
Thanks in advance,
r.

Rene,
You can put a bunch of QLabels in a tight grid layout (set spacing to 0)
and then setPixmap() on each of the labels.

What I need to do is to generate one image (QPixmap, QImage, ... whatever) and save it as a file.
Any other hints?
Thanks anyway,
r.

Pretty straight forward, Create a new QPixmap of the correct size (add the widths, set the height)
Create a painter, with the pixmap as the device.
Draw a transparent background, then draw each pixmap in the correct location.

Thank you!
I didn't notice that QPixmap is a QPaintDevice : )

No problem... We have all been there... :) BTW, don't forget the transparent background fill on the image... Otherwise if your images that your painting have any transparent areas, they will show garbage...
QPixmap pm( w, h );
pm.fill( Qt::transparent )
QPainter painter( &pm )
...
