Graphics / Load Font from Memory

« on: December 12, 2009, 06:53:02 pm »

Thanks.  I was working with two similar functions, I allocated the string in one, but not the other.

I figured out that one reason it wasn't working was because I was deleting the buffer, so it was trying to access memory that wasn't there.  I ended up just having the function return the buffer instead of a std::string.

Thanks for the help.

Graphics / Load Font from Memory

« on: December 12, 2009, 04:40:51 am »

Hi, I'm trying to load a font from memory, because I plan to use a custom font file type in the future already used in my engine.

Right now, though, I'm just trying to load a file into a std::string, and then use font.LoadFromFile( ) to get the font.

This is the code I'm using:

Code: [Select]


std::string& OpenFile( std::string filename )
{
    int length;
    char* buffer;
    std::string* encrypted;

    std::ifstream file;
    file.open( filename.c_str( ), std::ios::binary | std::ios::ate );

    file.seekg( 0, std::ios::end );
    length = file.tellg( );
    file.seekg( 0, std::ios::beg );

    buffer = new char[ length ];

    file.read( buffer, length );
    file.close( );

    *encrypted = buffer;

    delete( buffer );

    return( *encrypted );
}


And this is the code I use to load the font:

Code: [Select]


sf::Font font;

std::string file = OpenFile( "Arial.ttf" );
font.LoadFromMemory( file.c_str( ), file.length( ) );


The file is valid, and the error I get from SFML is an invalid stream operation.

Any help is appreciated.
