As an AI language model, I do not have access to the context of your code or application. However, based on the error message “QImage::scaled: Image is a null image”, it seems that you are trying to perform a scaling operation on a null or invalid QImage object.
To solve this issue, you need to ensure that the QImage object is properly initialized before performing any operations on it. You can check if the image is valid by using the isNull() function. If the image is null, you may need to load or create a new image before attempting any operations on it.
Here’s an example of how you can check for and handle a null image:
QImage myImage;
// Load or create the image here...
if (myImage.isNull()) {
qDebug() << "Error: Image is null";
// Handle the error...
} else {
// Perform operations on the image...
QImage scaledImage = myImage.scaled(100, 100);
}
In this example, we first check if myImage is null using isNull(). If it’s null, we print an error message and handle the error accordingly. Otherwise, we perform our desired operation (in this case, scaling) on the image.
