Hi,
Am using suse9.1, kernel-2.6.4, my task is to display an image(preferbly bmp format) from binary data read by some sensors, using QT.am suing QT-3.3.1.
Not really! You're a bit vague... If you have an image in BMP format (or almost any other popular format for that matter) you can display it quite easily. Crib some code from the "showimg" example in the qt3-examples package. --

have seen showimg. in that they are simply taking one movie and displaying it on the scree, where as in my case, i don't have img, i myself need to prepare one image by any convertion method, which i don't know, and have to display that image on the scree, so basically wat i want to say is, i have just binary data file, so first with that data i need to make a bmp image file and then i have to display it!!

Have a look at: bool QImage::loadFromData ( const uchar * buf, uint len, const char * format) bool QImage::loadFromData ( QByteArray buf, const char * format = 0 ) and QImageIO if you want to define your own image format. Perhaps QImageIO can detect the image format by itself, otherwise you have to code your own format. best, Jeroen -- Kile - KDE Integrated LaTeX Editor http://kile.sourceforge.net
