how to display images in mosaic format?

[ChristianEhrlicher]

I don't understand what you're missing - why can't you simply paint your images one to each other onto your QLabel? What else needs to be done?

what I'm missing is combine multiple tiled geotiff images into one Image(QImage) and display.

I need to create tiled image from multiple images.

[ChristianEhrlicher]

Create a new QImage and paint on it with QPainter

Sorry, It is not as simple.Since it is GIS map I'm expecting for a solution to merge more than one images into a single image and display .
Merging is the problem(based on lat/lon) .it needs to merged.

Thank you for your suggestion

Tiling concept is available in gdal . The proper sequential use of it in Qt is what now I'm looking forward.

I don't see what this has to do with Qt but ...

[Nithya]

As I told you before stitching more than one Image into a single image before displaying is what I need to do with Qt.

Any function is available to append a QImage type to another QImage type and to display as single image.(without any space in between).

Why cnt u make a function yourself ?

or may be QImage::bitBlt might be useful to u ?
