class TASImage: public TImage


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.

Function documentation

void DestroyImage()
 Destroy image.
void SetDefaults()
 Set default parameters.
TASImage()
 Default image constructor.
TASImage(UInt_t w, UInt_t h)
 Create an empty image.
TASImage(const char* file, TImage::EImageFileTypes type = kUnknown)
 Create an image object and read from specified file.
 For more information see description of function ReadImage()
 which is called by this constructor.
TASImage(const char* name, const Double_t* imageData, UInt_t width, UInt_t height, TImagePalette* palette = 0)
 Create an image depending on the values of imageData.
 For more information see function SetImage() which is called
 by this constructor.
TASImage(const char* name, const TArrayD& imageData, UInt_t width, TImagePalette* palette = 0)
 Create an image depending on the values of imageData.
 The size of the image is width X (imageData.fN / width).
 For more information see function SetImage() which is called by
 this constructor.
TASImage(const char* name, const TVectorD& imageData, UInt_t width, TImagePalette* palette = 0)
 Create an image depending on the values of imageData.
 The size of the image is width X (imageData.fN / width).
 For more information see function SetImage() which is called by
 this constructor.
TASImage(const TASImage& img)
 Image copy constructor.
TASImage & operator=(const TASImage& img)
 Image assignment operator.
~TASImage()
 Image destructor, clean up image and visual.
const char * TypeFromMagicNumber(const char* file)
 Guess the file type from the first byte of file.
void ReadImage(const char* file, TImage::EImageFileTypes type = TImage::kUnknown)
 Read specified image file.
 The file type is determined by the file extension (the type argument is
 ignored). It will attempt to append .gz and then .Z to the filename and
 find such a file. If the filename ends with extension consisting of digits
 only, it will attempt to find the file with this extension stripped
 off. On success this extension will be used to load subimage from
 the file with that number. Subimage is supported for GIF files
 (ICO, BMP, CUR, TIFF, XCF to be supported in future).
  For example,
    i1 = TImage::Open("anim.gif.0"); // read the first subimage
    i4 = TImage::Open("anim.gif.3"); // read the forth subimage

 It is also possible to put XPM raw string (see also SetImageBuffer) as
 the first input parameter ("filename"), such string  is returned by
 GetImageBuffer method.
void WriteImage(const char* file, TImage::EImageFileTypes type = TImage::kUnknown)
 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 posiible to write image into an animated GIF file by specifying file
 name as "myfile.gif+" of "myfile.gif+NN", where NN is delay of displaying
 subimages during animation in 10ms seconds units.
 If NN is ommitted the delay between subimages is zero.
 For repeated animation the last subimage must be specified as
 "myfile.gif++NN", where NN is number of cycles. If NN is ommitted the
 animation will be infinite.

 The following macro creates animated gif from jpeg images with names
    imageNN.jpg, where 1<= NN <= 10
 {
    TImage *img = 0;
    gSystem->Unlink("anim.gif");  // delete existing file

    for (int i = 1; i <= 10; i++) {
       delete img; // delete previous image

       // Read image data. Image can be in any format, e.g. png, gif, etc.
       img = TImage::Open(Form("image%d.jpg", i));

       if (i < 10) {
          img->WriteImage("anim.gif+");
       } else { // the last image written.  "++" stands for infinit animation.
          img->WriteImage("anim.gif++");
       }
    }
 }
TImage::EImageFileTypes GetFileType(const char* ext)
 Return file type depending on specified extension.
 Protected method.
void MapFileTypes(TImage::EImageFileTypes& type, UInt_t& astype, Bool_t toas = kTRUE)
 Map file type to/from AfterImage types.
 Protected method.
void MapQuality(TAttImage::EImageQuality& quality, UInt_t& asquality, Bool_t toas = kTRUE)

 The color of each pixel depends on the imageData of the corresponding
 pixel. The palette is used to convert an image value into its color.
 If palette is not defined (palette = 0) a default palette is used.
 Any previously defined zooming is reset.
void SetImage(const TArrayD& imageData, UInt_t width, TImagePalette* palette = 0)
 Delete the old image and creates a new image depending on the values
 of imageData. The size of the image is width X (imageData.fN / width).
 The color of each pixel depends on the imageData of the corresponding
 pixel. The palette is used to convert an image value into its color.

 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

 no hue - the will not get adjusted. Only saturation and value will be

          to right, 90 means top to bottom, etc.

          ranging from 0.0 to 1.0.  The colors from the colors attribute
          are given these offsets, and the final gradient is rendered
          from the combination of the two.  If both colors and offsets
          are given but the number of colors and offsets do not match,
          the minimum of the two will be used, and the other will be
          truncated to match.  If offsets are not given, a smooth
          stepping from 0.0 to 1.0 will be used.
