Newbie question 
Is the only way to get a larger font size when using textout or textprintf to create a custom font? Or maybe some other output function I should use?
I don't mind using the default font but I just want it to be bigger.

]]>Yes, Allegro can't use true type fonts, only bitmap-based ones. So, you need to create your own font with the size you want.
]]>Or you could just write a function to stretch the default font...something like this:
| 1 | // width and height are per character |
| 2 | BITMAP* magnifyText(char* message, int width, int height, int r, int g, int b) |
| 3 | { |
| 4 | // create bitmap to stretch_blit |
| 5 | // default font is 8x8 I believe |
| 6 | BITMAP* character = create_bitmap(8,8); |
| 7 | clear_to_color(character, makecol(255,255,255)); |
| 8 | |
| 9 | // get size of message |
| 10 | int size = 0; |
| 11 | for (; message[size] != '\0'; size++); |
| 12 | |
| 13 | // create bitmap to return |
| 14 | BITMAP* text = create_bitmap(width*size, height); |
| 15 | clear_to_color(text, makecol(255,255,255)); |
| 16 | |
| 17 | // stretch the message |
| 18 | for (int i = 0; i < size; i++) |
| 19 | { |
| 20 | textprintf_ex(character,font,0,0,makecol(r,g,b),-1,"%c",message<i>); |
| 21 | stretch_blit(character,text,0,0,8,8,i*width,0,width,height); |
| 22 | clear_to_color(character, makecol(255,255,255)); |
| 23 | } |
| 24 | return text; |
| 25 | } |
| 26 | |
| 27 | // then somewhere, just... |
| 28 | masked_blit(magnifyText("this is 10x10 pixels",10,10,255,255,255), ...); |
This is untested code, but it looks to me like it would work. There may be some modifications to make it better...
]]>Thanks. I was looking at the api and didn't any obvious 'increment here to increase font' values.
I'll try both suggestions 
// get size of message int size = 0; for (; message[size] != '\0'; size++);
How bout this instead:
int size = strlen(message);
// get size of message
int size = 0; for (; message[size] != '\0'; size++);
How bout this instead:
int size = strlen(message);
strlen() requires you to #include <string>. With my method, you don't need to include strings. So, if you're already using string objects, I suppose it would be better to use strlen(), however, if you don't have any other string objects I think my method would be better because then you don't have to include and entire file just for one function.
]]>actually, it requires you to include string.h, or cstring, depending on if you use C, or C++ (in that order) also, C strings are not objects, they are plain arrays of char. And its always best to use the provided standard functions.
]]>And what's wrong with Allegro's ustrlen()?
