Albert Astals Cid 4692a34a1c QStringLiteral is a bit faster here 2019-04-17 17:37:28 +02:00
Albert Astals Cid 83d1ca90d9 Fix compilation 
Summary:
Seems only gcc can do a constexpr with strlen.

This fixes the build with clang, hopefully to with MSVC?

Albert Astals Cid 9fc6967f4f Fix RGBHandler::canRead 
Summary:
As one can see in SGIImage::readImage the accepted images are

    _stream >> u16;
    if (u16 != 0x01da) {
        return false;
    }

    _stream >> _rle;
    if (_rle > 1) {
        return false;
    }

so not only \x01\xda\x01 but also \x01\xda\x00

Albert Astals Cid 20100a1e0e ras: fix crash on broken files 
Replace QVector::operator[] with QVector::value() since we can't know for
sure the values will be on range so use value() that gives us a 0 if the
index is not on range

Albert Astals Cid 55af097749 Don't warn the user/developer about something he can't fix 
image formats are loaded via qimage/qimagereader and friends, the user/developer does not choose which ones will be used so giving him a warning about sequential devices not being supported is not going to help anyone, only spam their shell/logs.
