TImage attributes.
Image attributes are:
This class is used (in general by secondary inheritance) by some other classes (image display).

TAttImage::TAttImage | ( | ) |
TAttImage default constructor.
Calls ResetAttImage to set the attributes to a default state.

TAttImage::TAttImage | ( | EImageQuality | lquality, |
UInt_t | lcompression, | ||
Bool_t | constRatio | ||
) |
TAttImage normal constructor.
Image attributes are taken from the argument list
[in] | lquality | must be one of EImageQuality (kImgDefault is same as kImgGood in the current implementation) |
[in] | lcompression | defines the compression rate of the color data in the image. Speed and memory depends on this rate, but not the image display itself 0: no compression; 100: max compression |
[in] | constRatio | keeps the aspect ratio of the image constant on the screen (in pixel units) |

Set (constRatio = kTRUE) or unset (constRadio = kFALSE) the ratio flag.
The aspect ratio of the image on the screen is constant if the ratio flag is set. That means one image pixel is always a square on the screen independent of the pad size and of the size of the zoomed area.
