Public Methods

Image()

Image(const Image& image, const CopyOp& copyop=CopyOp::SHALLOW_COPY)

Copy constructor using CopyOp to manage deep vs shallow copy

virtual Object* cloneType() const

virtual Object* clone(const CopyOp& copyop) const

virtual bool isSameKindAs(const Object* obj) const

virtual const char* className() const

inline const std::string& getFileName() const

void setFileName(const std::string& fileName)

void setImage(const int s, const int t, const int r, const int internalFormat, const unsigned int pixelFormat, const unsigned int dataType, unsigned char* data, const int packing=-1)

set the image data and format.

inline const int s() const

Width of image

inline const int t() const

Height of image

inline const int r() const

Depth of image

inline const int internalFormat() const

inline const unsigned int pixelFormat() const

inline const unsigned int dataType() const

raw image data

inline const unsigned char* data() const

raw const image data

void scaleImage(const int s, const int t, const int r)

Scale image to specified size.

void ensureDimensionsArePowerOfTwo()

Ensure image dimensions are a power of two.

inline void dirty()

Dirty the image, which increments the modified flag, to force osg::Texture to reload the image

inline void setModifiedTag(const unsigned int value)

Set the modified tag value, only used by osg::Texture when using texture subloading.

inline const unsigned int getModifiedTag() const

Get modified tag value, only used by osg::Texture when using texture subloading.

void setImage(const int s, const int t, const int r, const int internalFormat, const unsigned int pixelFormat, const unsigned int dataType, unsigned char* data, const int packing=-1)

set the image data and format. note, when the packing value is negative (the default is -1) this method assumes a _packing width of 1 if the width is not a multiple of 4, otherwise automatically sets to _packing to 4. If a positive value of packing is supplied than _packing is simply set to that value.

void scaleImage(const int s, const int t, const int r)

Scale image to specified size.

void ensureDimensionsArePowerOfTwo()

Ensure image dimensions are a power of two. Mip Mapped texture require the image dimensions to be power of two.

inline void dirty()

Dirty the image, which increments the modified flag, to force osg::Texture to reload the image

inline void setModifiedTag(const unsigned int value)

Set the modified tag value, only used by osg::Texture when using texture subloading.

inline const unsigned int getModifiedTag() const

Get modified tag value, only used by osg::Texture when using texture subloading.
