RE: Re: [ft] Monochrome Bitmap Trouble

[Paresh Deshmukh]

I think my comment cause more trouble then bitmap trouble ;).. Well those
comments are for myself Im a beginner and don't want to miss out anything.
Sorry for the trouble.

I cannot send you the real program. But this is based on the tutorial step-1.
The addition is only that...image buffer is copied to print buffer.

I also tried similar code as of

void InitFont() {
        FT_UInt index;
        FT_GlyphSlot slot;
        int pitch, start;
        unsigned char *bitmap, i;

        if ( FT_Init_FreeType(&Library) ) {
                printf("Failed to init freetype.\n");
                exit(1);
        }

        if ( FT_New_Face(Library, "/arial.ttf", 0, &face) )
                printf("Unable to load font.\n");

        if ( FT_Set_Char_Size(face, 0, 22*64, 300,300) )
                printf("Unable to set character size.\n");


        for (i = 'A'; i < 'A' + 4; i++) {
                index = FT_Get_Char_Index(face, i);

                if ( FT_Load_Glyph(face, index, FT_LOAD_DEFAULT) )
                        printf("Unable to load glyph face.\n");

                if ( FT_Render_Glyph(face->glyph, ft_render_mode_mono) )
                        printf("Unable to render glyph\n");

                slot   = face->glyph;
                pitch  = slot->bitmap.pitch;

                bitmap = (unsigned char *) malloc(slot->bitmap.rows * pitch);

                if (bitmap == NULL) {
                        printf("Out of memory.\n");
                        free(bitmap);
                        FT_Done_FreeType(Library);
                        exit(1);
                }
                memset(bitmap, 0, slot->bitmap.rows * pitch);

                for (start=0; start < slot->bitmap.rows; start++)
                        memcpy(bitmap + pitch * start,slot->bitmap.buffer + 
start * pitch, pitch);
}

                /*Cpying bitmap to print buffer*/

                free(bitmap);

        }

        FT_Done_FreeType(Library);
}

This code works for me and giving me proper and all characters without any
garbage. Please comment where Im wrong in first code.
