Save picture in bmp format

[descom_g]

Hello,

I want to save a picture from my camera in a bmp format.
I use a QImageEncoderSettings class to do it but I cannot save in bmp format, I read the docs about this class but I still dont success to use correctly the "setCodec" to have the bmp format.

Thanks for your help.

Hi and welcome to devnet,

Please show the code you use to save your images.

 auto filename = QFileDialog::getSaveFileName(this, tr("Save Image"), ".", tr("Image (*.bmp)"));
    if (filename.isEmpty())
        return;
    mCameraImageCapture->setCaptureDestination(QCameraImageCapture::CaptureToFile);
    QImageEncoderSettings imageSettings;
    imageSettings.setCodec("bmp");
    imageSettings.setResolution(1024, 1280);
    mCameraImageCapture->setEncodingSettings(imageSettings);
    mCamera->setCaptureMode(QCamera::CaptureStillImage);
    mCamera->start();
    mCamera->searchAndLock();
    mCameraImageCapture->capture(filename);
    mCamera->unlock();

The image still save on default(jpg) format with this code.

@descom_g Shouldn't it be

imageSettings.setCodec("image/bmp");

?

hi
Try to list the codec available to be sure

foreach(const QString &codecName, imagecapture->supportedImageCodecs()) {
qDebug() << ...

I am trying to do the same on Windows and not able to set the image format. supportedImageCodecs() returns an empty list. Does anyone know a workaround to set image encoding on Windows?
