printy$="X"
SYS"Font_FindFont",,"Homerton.Bold"+CHR$(0),300*16,300*16,90,90 TO handle%
SYS"Font_SetFontColours",handle%,15,0,14
SYS"Font_Paint",handle%,printy$,%10010,400,400
SYS"Font_LoseFont",handle%
Should print a 300 point X in Homerton Bold at around 400,400 in colour 15 on a colour 0 background - on a MODE 20 greyscale screen it looks suitably large  I'll leave it as an excercise for the reader to modify it to do something sensible.
[edit]
OK, something not sensible:

(set type to BASIC)

Do you mean text in a large font or a large amount of data? I assume you mean the former, and also that you meant BASIC.
There are several ways.
There is IIRC a VDU command to draw text at double height. Then you need to print the text twice because it only draws half at a time. I don't remember the details, but it works quite well and you can even colour the top and bottom half of the text different colours.
In fact I think there may be another VDU call which will let you draw text in any size. It does get a bit blocky at larger sizes though because it uses the 8*8 character bitmaps.
You could use an anti-aliased font, with the appropriate SYS calls. These look really nice but you need to set things up correctly. I've not done this but it is certainly possible.
You could design your own characters using data statements and BASIC's draw commands (ie MOVE x,y DRAW x,y FILL x,y. Give each different command you implement a different type then store type,x,y[,...] Load these characters into an array at initialisation, and write a procedure to plot the text. (I've done this before.)
Or you could design a set of sprites which have one character each, then load the spritefile and plot them using SYS"OS_SpriteOp" calls.
Or something else I've not thought of... |
