BennuGD has seen a lot of improvements lately. As writing about all of them in a single post would result in a boringly long one, I’m going to write a series of articles highlighting some improvements I find interesting.
Late last year (28th December) Splinter added two new functionalities to fnt_new(). They’re used with the following syntax:
FNT_NEW (CHARSET, DEPTH);
FNT_NEW (FILE, GRAPH, CHARSET, WITDH, HEIGHT, FIRST, LAST, FLAGS);
Read on for more details.
As you can see, there’s now a new CHARSET parameter which can be one of these:
This way, you can control the charset used in your new font.
Not only that, but there’s a new FLAGS parameter, which can be one of:
This way, you can specify if your new font will be monospaced or not.
With this new functionality, you’ll be able to create a new font in memory from a bitmap that’s already been loaded. Splinter posted the following code showing the effect.
import "mod_video"; import "mod_wm"; import "mod_text"; import "mod_map"; import "mod_key"; private a,b,c; g; font, font2; begin set_mode(640,480); g = png_load("font.png"); font = fnt_new(0,g,CHARSET_ISO8859,16,16,0,255,0); write_int(font,0,0,0,&a); write_int(font,0,20,0,&b); write_int(font,0,40,0,&c); write(font,0,60,0,"hello world!"); write_int(0,320,0,0,&a); write_int(0,320,20,0,&b); write_int(0,320,40,0,&c); write(0,320,60,0,"hello world!"); font2 = fnt_new(0,g,CHARSET_ISO8859,16,16,0,255,1); write_int(font2,0,100,0,&a); write_int(font2,0,120,0,&b); write_int(font2,0,140,0,&c); write(font2,0,160,0,"hello world!"); while( !key( _ESC ) && !exit_status ) a++; b--; c*=2; if ( c == 0 ) c = 1; end frame; end end
The code will take a bitmap such as this one:
And use it to first create a font in memory (that you can later save with fnt_save()) and write some text to the screeen, both in fixed-width and variable width forms:
Hope you find it useful!
PS: This new functionality still needs to be documented, would you like to do it? Go the the fnt_new() page in the wiki and add the relevant info!
