Image class.
TASImage is the concrete interface to the image processing library libAfterImage.
It allows reading and writing of images in different formats, several image manipulations (scaling, tiling, merging, etc.) and displaying in pads. The size of the image on the screen does not depend on the original size of the image but on the size of the pad. Therefore it is very easy to resize the image on the screen by resizing the pad.
Besides reading an image from a file an image can be defined by a two dimensional array of values. A palette defines the color of each value.
The image can be zoomed by defining a rectangle with the mouse. The color palette can be modified with a GUI, just select StartPaletteEditor() from the context menu.
Several examples showing how to use this class are available in the ROOT tutorials: $ROOTSYS/tutorials/visualisation/image/

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.
In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.
The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();
(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

This function will tile original image to specified size with offsets requested, and then it will go though it and adjust hue, saturation and value of those pixels that have specific hue, set by affected_hue/ affected_radius parameters.
When affected_radius is greater then 180 entire image will be adjusted. Note that since grayscale colors have no hue - the will not get adjusted. Only saturation and value will be adjusted in gray pixels.
Hue is measured as an angle on a 360 degree circle, The following is relationship of hue values to regular color names :
All the hue values in parameters will be adjusted to fall within 0-360 range.
| [in] | hue | hue in degrees in range 0-360. This allows to limit impact of color adjustment to affect only limited range of hues. |
| [in] | radius | value in degrees to be used in order to calculate the range of affected hues. Range is determined by substracting and adding this value from/to affected_hue. |

Write this object to the current directory.
The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".
Writing an object to a file involves the following steps:
Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.
If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().
The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.
An object is read from the file into memory via TKey::Read() or via TObject::Read().
The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.

Write image to specified file.
If there is no file extension or if the file extension is unknown, the type argument will be used to determine the file type. The quality and compression is derived from the TAttImage values.
It's possible to write image into an animated GIF file by specifying file name as "myfile.gif+" or "myfile.gif+NN", where NN is the delay of displaying subimages during animation in 10ms seconds units. NN is not restricted to two digits. If NN is omitted the delay between subimages is zero. For an animation that stops after last subimage is reached, one has to write the last image as .gif+ (zero delay of last image) or .gif+NN (NN*10ms delay of last image).
For repeated animation (looping), the last subimage must be specified as:
A deprecated version for saving the last subimage of a looping gif animation is:

The area of an image displayed in a pad is defined by this function.
Note: the size on the screen is defined by the size of the pad. The original image is not modified by this function. If width or height is larger than the original image they are reduced to the width and height of the image. If the off values are too large (off + width > image width) than the off values are decreased. For example: offX = image width - width Note: the parameters are always relative to the original image not to the size of an already zoomed image.
