600 cigarettes per pound so 16 ounces divided into that is .03 ounces per cigarette or 6 ounces per carton. so 0.6 ounces per pack so the shell weighing .4 to .5 ounces makes sense I guess. Metric scale to .001 ounce needed.
A bitmap is a type of memory organization or image file format used to store digital images. The term bitmap comes from the computer programming terminology, meaning just a map of bits, a spatially mapped array of bits. DIB is an external format, in contrast to a device-dependent bitmap, which appears in the system as a bitmap object (created by an application...). A DIB is normally transported in metafiles (usually using the StretchDIBits() function), BMP files, and the Clipboard (CF_DIB data format).
The resulting bitmap is refered to as monochrome or black and white. The pixels with a 0 are refered to as black, pixels with a 1 are refered to as white. Note that while only two states are possible they could be interpreted as any two colours, 0 is mapped to one colour, 1 is mapped to another colour.
