Hi. Well, it's working. Here's what I've done:

QFile f("D:/img.bin"); if(f.open(QIODevice::ReadOnly)){ QByteArray b = f.readAll(); QImage img((const uchar*) b.constData(), 4096, 2160, 4096, QImage::Format_Indexed8); QVector<QRgb> colorTable; for (int i = 0; i < 256; i++){ colorTable.push_back(qRgb(i,i,i)); } img.setColorTable(colorTable); img.save("D:/img.png"); f.close(); }

And here's what I got:

Do you have Qt configured to use that display ?

Hi and welcome to devnet,

AFAIK, you need to go lower level in order to modify the type of the generated image
