sfText * sfText_copy | ( | const sfText * | text | ) |

Copy an existing text.

Parameters

  text | Text to copy

Returns
  Copied object

## ◆ sfText_create()

sfText * sfText_create | ( | const sfFont * | font | ) |

Create a new text.

Parameters

## ◆ sfText_findCharacterPos()

sfVector2f sfText_findCharacterPos | ( | const sfText * | text,
|  | size_t | index )

Return the position of the index-th character in a text.

This function computes the visual position of a character from its index in the string. The returned position is in global coordinates (translation, rotation, scale and origin are applied). If index is out of range, the position of the end of the string is returned.

Parameters

  text | Text object
  index | Index of the character

Returns
  Position of the character

## ◆ sfText_getCharacterSize()

unsigned int sfText_getCharacterSize | ( | const sfText * | text | ) |

Get the size of the characters of a text.

Parameters

Returns
  Size of the characters

## ◆ sfText_getFillColor()

sfColor sfText_getFillColor | ( | const sfText * | text | ) |

Get the fill color of a text.

Parameters

  text | Text object

Returns
  Fill color of the text

## ◆ sfText_getFont()

const sfFont * sfText_getFont | ( | const sfText * | text | ) |

Get the font used by a text.

If the text has no font attached, a NULL pointer is returned. The returned pointer is const, which means that you can't modify the font when you retrieve it with this function.

Parameters

  text | Text object

Returns
  Pointer to the font

## ◆ sfText_getGlobalBounds()

sfFloatRect sfText_getGlobalBounds | ( | const sfText * | text | ) |

Get the global bounding rectangle of a text.

The returned rectangle is in global coordinates, which means that it takes in account the transformations (translation, rotation, scale, ...) that are applied to the entity. In other words, this function returns the bounds of the text in the global 2D world's coordinate system.

Parameters

  text | Text object

Returns
  Global bounding rectangle of the entity

## ◆ sfText_getInverseTransform()

sfTransform sfText_getInverseTransform | ( | const sfText * | text | ) |

Returns
  Size of the line spacing factor

See also
  sfText_setLineSpacing

## ◆ sfText_getLocalBounds()

sfFloatRect sfText_getLocalBounds | ( | const sfText * | text | ) |

Get the local bounding rectangle of a text.

Returns
  Local bounding rectangle of the entity

## ◆ sfText_move()

void sfText_move | ( | sfText * | text,
|  | sfVector2f | offset )

Move a text by a given offset.

This function adds to the current position of the object, unlike sfText_setPosition which overwrites it.

Parameters

  text | Text object
  offset | Offset

## ◆ sfText_rotate()

void sfText_rotate | ( | sfText * | text,
|  | float | angle )

Rotate a text.

This function adds to the current rotation of the object, unlike sfText_setRotation which overwrites it.

Parameters

  text | Text object
  angle | Angle of rotation, in degrees

## ◆ sfText_scale()

void sfText_scale | ( | sfText * | text,
|  | sfVector2f | factors )

Scale a text.

This function multiplies the current scale of the object, unlike sfText_setScale which overwrites it.

Parameters

  text | Text object
  factors | Scale factors

## ◆ sfText_setCharacterSize()

void sfText_setCharacterSize | ( | sfText * | text,
|  | unsigned int | size )

Set the character size of a text.

The default size is 30.

Parameters

  text | Text object
  size | New character size, in pixels

## ◆ sfText_setFillColor()

void sfText_setFillColor | ( | sfText * | text,
|  | sfColor | color )

Set the fill color of a text.

By default, the text's fill color is opaque white. Setting the fill color to a transparent color with an outline will cause the outline to be displayed in the fill area of the text.

Parameters

  text | Text object
  color | New fill color of the text

## ◆ sfText_setFont()

void sfText_setFont | ( | sfText * | text,
|  | const sfFont * | font )

Set the font of a text.

The font argument refers to a texture that must exist as long as the text uses it. Indeed, the text doesn't store its own copy of the font, but rather keeps a pointer to the one that you passed to this function. If the font is destroyed and the text tries to use it, the behaviour is undefined.

Parameters

  text | Text object
  font | New font

## ◆ sfText_setLetterSpacing()

void sfText_setLetterSpacing | ( | sfText * | text,
|  | float | spacingFactor )

Set the letter spacing factor.

The default spacing between letters is defined by the font. This factor doesn't directly apply to the existing spacing between each character, it rather adds a fixed space between them which is calculated from the font metrics and the character size. Note that factors below 1 (including negative numbers) bring characters closer to each other. By default the letter spacing factor is 1.

Parameters

  text | Text object
  spacingFactor | New letter spacing factor

See also
  sfText_getLetterSpacing

## ◆ sfText_setLineSpacing()

void sfText_setLineSpacing | ( | sfText * | text,
|  | float | spacingFactor )

Set the line spacing factor.

The default spacing between lines is defined by the font. This method enables you to set a factor for the spacing between lines. By default the line spacing factor is 1.

Parameters

  text | Text object
  spacingFactor | New line spacing factor

See also
  sfText_getLineSpacing

## ◆ sfText_setOrigin()

void sfText_setOrigin | ( | sfText * | text,
|  | sfVector2f | origin )

Set the local origin of a text.

The origin of an object defines the center point for all transformations (position, scale, rotation). The coordinates of this point must be relative to the top-left corner of the object, and ignore all transformations (position, scale, rotation). The default origin of a text object is (0, 0).

Parameters

  text | Text object
  origin | New origin

## ◆ sfText_setOutlineColor()

void sfText_setOutlineColor | ( | sfText * | text,
|  | sfColor | color )

Set the outline color of the text.

By default, the text's outline color is opaque black.

Parameters

  text | Text object
  color | New outline color of the text

## ◆ sfText_setOutlineThickness()

void sfText_setOutlineThickness | ( | sfText * | text,
|  | float | thickness )

Set the thickness of the text's outline.

By default, the outline thickness is 0.

Be aware that using a negative value for the outline thickness will cause distorted rendering.

Parameters

  text | Text object
  thickness | New outline thickness, in pixels

See also
  getOutlineThickness

## ◆ sfText_setPosition()

void sfText_setPosition | ( | sfText * | text,
|  | sfVector2f | position )

Set the position of a text.

This function completely overwrites the previous position. See sfText_move to apply an offset based on the previous position instead. The default position of a text Text object is (0, 0).

Parameters

  text | Text object
  position | New position

## ◆ sfText_setRotation()

void sfText_setRotation | ( | sfText * | text,
|  | float | angle )

Set the orientation of a text.

This function completely overwrites the previous rotation. See sfText_rotate to add an angle based on the previous rotation instead. The default rotation of a text Text object is 0.

Parameters

  text | Text object
  angle | New rotation, in degrees

## ◆ sfText_setScale()

void sfText_setScale | ( | sfText * | text,
|  | sfVector2f | scale )

Set the scale factors of a text.

This function completely overwrites the previous scale. See sfText_scale to add a factor based on the previous scale instead. The default scale of a text Text object is (1, 1).

Parameters

  text | Text object
  scale | New scale factors

## ◆ sfText_setString()

void sfText_setString | ( | sfText * | text,
|  | const char * | string )

Set the string of a text (from an ANSI string).

A text's string is empty by default.

Parameters

  text | Text object
  string | New string
