Graphic Support By Visual Basic
Storing and accesing Graphics data Require Complex Data
Strucrures.While Declaring the data Structures for accesing the
graphics data many factors should be considered like
1) The Image Data formats
2) The Disk Space Required
3) The Speed at which the data can be accessed
So the Support extended by a Software are restricted to
the vast image formats that release nowadays.

5) and 24 bit formats
There are subcategory at the level of bitmaps they are
