C++ (Cpp) CBitmap::convertToType Examples

Example #1

File: texture_chooser.cpp Project: sythaeryn/pndrpg

void TextureChooser::onFileTxtRowChanged( int row )
{
	if( row < 0 )
		return;

	QListWidgetItem *item = d_ptr->fileTextures->item( row );
	QString fn = item->text();

	std::string rfn = fn.toUtf8().constData();
	rfn = NLMISC::CPath::lookup( rfn );
	
	NLMISC::CIFile f;
	bool b = f.open( rfn );
	if( !b )
	{
		return;
	}

	NLMISC::CBitmap bm;
	uint8 depth = bm.load( f );
	f.close();
	b = bm.convertToType( NLMISC::CBitmap::RGBA );
	if( !b )
	{
		return;
	}

	setPreviewImage( bm );

Example #2

bool CIconWnd::loadIcon(const std::string &filename, NLMISC::CBitmap &bmp)
{
    // Try to get the file path
    string filepath = CPath::lookup(filename, false, false);
    if (filepath == "")
    {
        bmp.makeDummy();
        bmp.convertToType(NLMISC::CBitmap::RGBA);
        bmp.resample(40, 40);
        return false;
    }

    // load icon
    CIFile f;
    f.open(filepath);

    bmp.load(f);
    bmp.convertToType(NLMISC::CBitmap::RGBA);
    bmp.resample(40, 40);

    f.close();

    return true;
