virtual ~TextRenderStrategy()#
-
virtual TextRenderStrategy *newInstance() const = 0#
Copy the current TextRenderStrategy implementation into an new object.
-
virtual void boundingBox(const std::string &string, const TextProperties &tprop, int bbox[4]) const = 0#
Calculate a bounding box.
- Parameters:
string – The text.
tprop – The properties.
bbox – The result in pixels (left, right, top, bottom).
-
virtual void render(const std::string &string, const TextProperties &tprop, unsigned char *buffer, const Vector2i &dims) const = 0#
render Render the string.
- Parameters:
string – The text.
tprop – The properties.
buffer – The target. Must be dims[0]*dims[1]*4 bytes. The buffer will be filled with RGBA image data, with the top scan row at the beginning.
dims – Dimensions in pixels of the target buffer.
