How to get the size of an WImage?
Added by Ezgi Cicek about 14 years ago
I am trying to get the size of an WImage that has a file resource from local directory.
WImage * image;
// assuming I have set the resource in fileUploaded()
then
image->width().toPixels() doesnt give me the width.
What should I do to get the width and height of my WImage?

Hey,
The server isn't actually aware --- only the browser is.
There is a small utility that we use (in WPainter) to read the size of a PNG or GIF file.
You can use it like this:
WPainter::Image::Image image(fileName, fileName);
std::cerr << image.width() << ", " << image.height() << std::endl;
