Creates a memory bitmap from the freetype glyph.
Member Function Documentation
| int VRS::ImageGlyph::width | ( | ) | const |
Returns the width of the contained image.
| int VRS::ImageGlyph::height | ( | ) | const |
Returns the height of the contained image.
| int VRS::ImageGlyph::pitch | ( | ) | const |
Returns the pitch of the contained image.
| MemoryImage* VRS::ImageGlyph::getAlphaImage | ( | ) | const |
Returns an image containing the glyph.
Returns 0, if the image is empty (e.g. space) as all other image related get methods do.
| ImageTexture2D* VRS::ImageGlyph::getTexture | ( | ) | const |
Returns a texture with the glyph as image.
| ImageTexture2D* VRS::ImageGlyph::getHaloedTexture | ( | double | haloeSize | ) | const |
Like getTexture, but the glyph will have a haloe around it.
The haloe range is specified in texture pixels (square with 2*haloeSize edge length)
| unsigned char* VRS::ImageGlyph::getBitmapImage | ( | ) | const |
Returns a bitwise stored image (one bit = one pixel).
| Vector VRS::ImageGlyph::getLowerLeftCorner | ( | ) | const |
Returns the difference between the origin and the lower left corner of the glyph (in pixels).
Consider the glyph is a p. The origin (0,0,0) obviously differs from the lower left corner of bitmap to render.
| virtual Bounds VRS::ImageGlyph::boundingBox | ( | ) | const [virtual] |
Implements VRS::Glyph.
