aXBottomRight X coordinate of the area bottom right corner

aYBottomRight Y coordinate of the area bottom right corner

aPixVal pixel value to fill non-overlaping zones (default (T)0)

Warning:
The intersection between the rectangle and the given image must be non-empty. If the overlaping zone is only partial, the non-overlaping zone(s) are filled with pixels having value aPixVal.

Todo:
To be reimplemented.

void qgar::GenImage< unsigned char , GenImage_NoCheck >::draw ( const Segment & aSeg,

value_type aPixVal = (value_type)1

) [inherited]

Warning:
Using this constructor may lead to serious bugs due to dynamic memory space management. Be sure that the value of the given reference counter (pointed by aPtRefCnt) is correct: If the given pixel map (pointed by aPtPixMap) is not shared by another object, this value must be 0. Otherwise, one must add 1 to the value, before using the constructor:
(*_pRefCnt)++;

Warning:
This kind of conversion must be explicitely specified by the client.

Todo:
Constructor qgar::GenImage::GenImage(AbstractPbmPlusFile&) should just work when T is instantiated by an unsigned char because function qgar::AbstractPbmPlusFile::readRow only works with rows of unsigned integers whereas the first argument of function qgar::GenImage::setRow is a pointer to a row of type T!
