Image class for encapsulating the storage texture image data

Image()

virtual Object* clone() 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. 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.
