glDrawPixels vs glBitmap rendering...

OpenGL OpenGL: Basic Coding

Hello,

I am using an FTLGish interface to freetype2. I have been able to draw the text successfully with glDrawPixels and textures, however, I get a distorted image when using glBitmap.

Here is a snippet of my glDrawPixels code that works:

glDisable (GL_ALPHA_TEST);
glEnable(GL_ALPHA);
glEnable (GL_BLEND);
glBlendFunc (GL_SRC_ALPHA,
GL_ONE_MINUS_SRC_ALPHA);
glPixelStorei (GL_UNPACK_ALIGNMENT, 1);

    // Move the glyph origin
    glBitmap( 0, 0,
	  0, 0,
	  -right,
	  -left,
	  NULL);

glDrawPixels (Width, Height, GL_ALPHA, GL_UNSIGNED_BYTE,(const GLubyte *) data);

    // Restore the glyph origin
    glBitmap( 0, 0,
	  0, 0,
	  right,
	  left,
	  NULL);

Using the same code replacing glDrawPixels with glBitmap:

    glBitmap(Width,
	 Height,
	 0, 0,
	 0, 0,
	 (const GLubyte*)data);

I get a distorted image rendered. (illegible fuzzy horizontal lines.)

What do I have to do differently to get glBitmap to render the image properly?

Thanks,
Mike.
