Thus type:
QBuffer* buffer = new QBuffer(this->Conex);
QImage* image = new QImage ();
image->loadFromData (buffer->buffer());
This does not work for me.

2Why, what happens when you try? – trojanfoe Sep 20 '11 at 14:12

1What kind of image data does `buffer` contain? – gnud Sep 25 '11 at 14:04

Put the data from the buffer into a QByteArray so you can have a look at how it looks like, then it will probably be more clear what needs to be done. – Johan Sep 26 '11 at 10:51

If the buffer contains raw pixel data, you might want to specify the width, height and bpp using this constructor:
QImage::QImage ( uchar * data, int width, int height, int bytesPerLine, Format format )
Edit:
That's how you would use this constructor:
int imageWidth = 800;
int imageHeight = 600;
int bytesPerPixel = 4; // 4 for RGBA, 3 for RGB
int format = QImage::Format_ARGB32; // this is the pixel format - check Qimage::Format enum type for more options
QImage image(yourData, imageWidth, imageHeight, imageWidth * bytesPerPixel, format);

this command line: QImage:: QImage (uchar * data, int width, int height, int bytesPerLine, Format format) Would use is it so? QImage image = new QImage (buffer, 600, 400, jpg) the bytesPerLine not they mean well, will the photo occupies kb? thanks – user950489 Sep 26 '11 at 09:06
