Arguments
| :: FontManager | The font manager. |
| -> StyleState | The style. |
| -> Text | The text to calculate. |
| -> Size | The calculated size. |
Returns the size a given text an style will take.
Arguments
| :: FontManager | The font manager. |
| -> StyleState | The style. |
| -> TextMode | Single or multiline. |
| -> TextTrim | Whether to trim or keep spaces. |
| -> Maybe Double | Optional max width (needed for multiline). |
| -> Maybe Int | Optional max lines. |
| -> Text | The text to calculate. |
| -> Size | The calculated size. |
Returns the size a given text an style will take.
Arguments
| :: FontManager | The font manager. |
| -> StyleState | The style. |
| -> TextOverflow | Whether to clip or use ellipsis. |
| -> TextMode | Single or multiline. |
| -> TextTrim | Whether to trim or keep spaces. |
| -> Maybe Int | Optional max lines. |
| -> Size | The bounding size. |
| -> Text | The text to fit. |
| -> Seq TextLine | The fitted text lines. |
Fits the given text to a determined size, splitting on multiple lines as needed. Since the function returns glyphs that may be partially visible, the text can overflow vertically or horizontally and a scissor is needed. The rectangles are returned with zero offset (i.e., x = 0 and first line y = 0), and a translation transform is needed when rendering.
Arguments
| :: FontManager | The fontManager. |
| -> StyleState | The style. |
| -> Double | The maximum width. |
| -> TextTrim | Whether to trim or keep spaces. |
| -> Text | The text to calculate. |
| -> Seq TextLine | The fitted text lines. |
Fits a single line of text to the given width, potencially spliting into several lines.
Arguments
| :: StyleState | The style. |
| -> Rect | The bounding rect. Text may overflow. |
| -> Seq TextLine | The TextLines to align. |
| -> Seq TextLine | The aligned TextLines. |
Aligns a Seq of TextLines to the given rect.
Moves a Seq of TextLines by the given offset.
