Text() [1/3]

void eVision::EWindowsDrawAdapter::Text ( const std::string & text, int32_t x, int32_t y, float orientation )

virtual

Draws a text.

Parameters

text	Text to draw.
x	X position of the text.
y	Y position of the text.
orientation	Orientation of the text in radians.

If desiredWidth is greater than 0, current font size will be ignored and a new one will be temporally set so that the whole drawn text fills in desiredWidth pixels.

Implements eVision::EDrawAdapter.

Parameters

text	Text to draw.
x	X position of the text.
y	Y position of the text.
orientation	Orientation of the text in radians.
textBrush	Optional brush to use for the color of the text.

If desiredWidth is greater than 0, current font size will be ignored and a new one will be temporally set so that the whole drawn text fills in desiredWidth pixels.

Implements eVision::EDrawAdapter.

Parameters

text	Text to draw.
x	X position of the text.
y	Y position of the text.
orientation	Orientation of the text in radians.
textBrush	Optional brush to use for the color of the text.
constraint	Text size constraint. By default, no constraint is to be applied.

If desiredWidth is greater than 0, current font size will be ignored and a new one will be temporally set so that the whole drawn text fills in desiredWidth pixels.
