widget to use for photo editing

[shift]

Hi everyone, I am soon to develop a piece of software that must handle a lot of photo editing and I have no clue which widget to use for the photo editing part of the software. Can it be a QGraphicsView maybe. I need to edit a photo in terms of changing the saturation, contrast, fading etc and on top of that I must be able to add text over a photo. Any help or ideas will be greatly appreciated in this regard.

thanks

There is no widget which will do what you want. There are Qt classes that will allow you to load images from files (QImage, QPixmap, QPicture, etc.) and display them (QGraphicsPixmapItem, QLabel), but nothing that gives you the image manipulation capabilities you describe right out of the box.

You might look into OpenCV - it may have many of the tools you are looking for to build a photo editing app using both OpenCV and Qt. I am assuming your goal is to produce the editing program and not reinvent all of the wheels involved in the processing algorithms themselves.

For display of an image QLabel is a good place to start.
