#define ulSetFont | ( | f | ) | (ul_curFont = f) |
Sets the current font.
#define ulPrintf_xy | ( | x, | |||
y, | |||||
format... | ) | ({ char __str[1000]; sprintf(__str , ##format); ulDrawString(x, y, __str); }) |
Draws text using printf format somewhere on the screen.
x,y | Positions where to draw the text | |
format | Printf-like string (ex: "%i", someInteger) |
void ulInitText | ( | ) |
Initializes the text system with the default supplied font (2 kB). Can be called several times, it will then only set the default font.
UL_FONT* ulCreateFont | ( | UL_FONTINFO * | fi | ) |
Creates a new font based on a FONTINFO header. Not very useful, as you should load fonts from a whole file. The only use it currently has is for the default font, which is embedded in the source code (but even there, you could only put the binary data of the file in a simple table and use a virtual file to open and load it).
UL_FONT* ulLoadFont | ( | VIRTUAL_FILE * | f | ) |
Loads a font from an open virtual file.
void ulDrawChar | ( | int | x, | |
int | y, | |||
unsigned char | c | |||
) |
Draws a character to the specified positions.
void ulDrawString | ( | int | x, | |
int | y, | |||
const char * | str | |||
) |
Draws a string to the specified positions.
Note: Drawing an entire string is faster than drawing characters individually.
void ulSetTextColor | ( | UL_COLOR | color | ) |
Sets the text color.
void ulDrawTextBox | ( | int | x0, | |
int | y0, | |||
int | x1, | |||
int | y1, | |||
const char * | text, | |||
int | format | |||
) |
Draws a text box.
x0,y0,x1,y1 | Rectangle where the text should be placed on. Text will automatically be word-wrapped (words are not cut in half at the end of a line) so make sure to let enough horizontal space else it will look ugly. | |
text | The text you want to draw. Currently, there is no special format tag supported. | |
format | For future use. Set it to zero for now. |
int ulGetStringWidth | ( | const char * | str | ) |
Returns the size of a string using the current active font.
int ulGetTextBoxHeight | ( | int | width, | |
int | maxHeight, | |||
const char * | text, | |||
int | format | |||
) |
Returns the height of a text box using the current active font.
width | Text box width (x1 - x0 in ulDrawTextBox) | |
maxHeight | Height limit. If set to 0, there will be no limit. | |
text | Text. | |
format | Let it to 0. |
Currently selected font.
Default LCD font (loaded upon call to ulInitConsole).
