| ) | [virtual] |
Draw an individual character of the font to the specified bitmap.
| bitmap | The bitmap to draw to. | |
| bitmapWidth | The width of the bitmap being drawn to. | |
| bitmapHeight | The height of the bitmap being drawn to. | |
| letter | The character to output. | |
| x | The x co-ordinate of the text. | |

Implements WoopsiUI::FontBase.
| u16 PackedFontBase::getCharWidth | ( | char | letter | ) | const [virtual] |
Get the width of an individual character.
| letter | The character to get the width of. |
Implements WoopsiUI::FontBase.
| u16 PackedFontBase::getStringWidth | ( | const char * | text, | |
| u16 | length | |||
| ) | const [virtual] |
Get the width of a string with a specified length in pixels when drawn with this font. Useful if you want to determine the width of a string without a terminator, or the width of a section of a string.
| text | The string to check. | |
| length | The length of the string in chars. |
Implements WoopsiUI::FontBase.
| u16 PackedFontBase::getStringWidth | ( | const char * | text | ) | const [virtual] |
Get the width of a string in pixels when drawn with this font.
| text | The string to check. |
Implements WoopsiUI::FontBase.
| const bool PackedFontBase::isCharBlank | ( | const char | letter | ) | const [virtual] |
Text uses this to decide whether a given character is blank or not
Decide whether a given character is blank or not

| ) | [pure virtual] |
Render an individual character of the font to the specified bitmap.
| pixelData | The font-specific pixel data | |
| pixelsPerRow | The number of pixels to render per row (for this character) | |
| bitmap | Top-left corner of output space to draw to. | |
| bitmapWidth | The width of the bitmap being drawn to. | |
| x | The x co-ordinate of the text. | |
| y | The y co-ordinate of the text. | |
| clipX1 | The left edge of the clipping rectangle. | |
| clipY1 | The top edge of the clipping rectangle. | |
| clipX2 | The right edge of the clipping rectangle. | |
| clipY2 | The bottom edge of the clipping rectangle. |
Implemented in WoopsiUI::PackedFont1, and WoopsiUI::PackedFont16.
| void WoopsiUI::PackedFontBase::setFontWidth | ( | u8 | fontWidth | ) | [inline] |
Makes this font fixed-width, though doesn't allow the spacing to be less than the font's known maximum character width. If you want fixed spacing but don't know the required size, pass 1.
| fontWidth | Font width to use (0 for proportional, 1 for wide-enough) |
