Error on trying to open a tif image file

[franco.amato]

I am developing a software that performs some image processing operations on tiff images.
I wrote a simple class that uses QImageReader to load the tiff files

#ifndef IMAGECROPPER_H
#define IMAGECROPPER_H

#include <QImage>
#include <QRect>
#include <QList>

class ImageCropper
{
public:
    struct CropArea
    {
        QRect rect;
        QPoint displayPos;
    };

    static QImage loadImage(const QString& filename);
    QList<QImage> cropImage(const QImage& image, const QList<CropArea> cropAreas);
};

#endif

And the cpp file

#include "ImageCropper.h"
#include <QImageReader>

QImage ImageCropper::loadImage(const QString &filename)
{
    return QImageReader(filename).read();
}

QList<QImage> ImageCropper::cropImage(const QImage &image, const QList<CropArea> cropAreas)
{
    QList<QImage> croppedImages;

    for (const CropArea &area : cropAreas)
    {
        QImage croppedImage = image.copy(area.rect);
        croppedImages.append(croppedImage);
    }

    return croppedImages;
}

Unfortunately when I try to load the image file I get this errors:

TIFFReadDirectory: Warning, Unknown field with tag 347 (0x15b) encountered.
foo: JPEG compression support is not configured.
TIFFReadDirectory: Warning, Unknown field with tag 347 (0x15b) encountered.
foo: JPEG compression support is not configured.
foo: Sorry, requested compression method is not configured.
Failed to load or crop image.

Is there a way to solve it?

Use libtiff directly with enabled jpeg support or provide a patch to Qt which enables it. Maybe it's worth creating a bug report.
