Description

In pdmodel/font/PDCIDFontType0.java :

public float getHeight(int code) throws IOException
{
    int cid = codeToCID(code);

    float height = 0;
    if (!glyphHeights.containsKey(cid))
    {
        height =  (float) getType2CharString(cid).getBounds().getHeight();
        glyphHeights.put(cid, height);
    }
    return height;
}

 
When the glyph is already in glyphHeights, getHeight returns 0.

It can be:

    public float getHeight(int code) throws IOException
    {
        int cid = codeToCID(code);

        float height = 0;
        if (!glyphHeights.containsKey(cid))
        {
            height =  (float) getType2CharString(cid).getBounds().getHeight();
            glyphHeights.put(cid, height);
        } else {
            height =  glyphHeights.get(cid);
        }
        return height;
    }
