Description
When I rotate an image (e.g. 90 degrees), the color profile information is lost. Here's an example:
for (int i = 0; i < 2; ++i) {
QImage qi(16, 16, QImage::Format_ARGB32);
qi.setColorSpace(QColorSpace(QColorSpace::AdobeRgb));
if (i)
qi = qi.transformed(QTransform().rotate(90));
qDebug() << qi.colorSpace().isValid() << qi.colorSpace().description();
}
The result is:
true "Adobe RGB" false ""
Same problem when loading an image (e.g. the attached TIFF) with orientation (from 4 to 7) using QImageReader and setAutoTrasform(true):
for (int i = 0; i < 2; ++i) {
QImageReader r("dice_r.tif");
r.setAutoTransform(i ? true : false);
auto qi = r.read();
qDebug() << qi.colorSpace().isValid() << qi.colorSpace().description();
}
The result is:
true "sRGB Linear build-in" false ""
