200 shells per carton. 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.
A bit map (often spelled bitmap) defines a display space and the color for each pixel or bit in the display space. A Graphics Interchange Format and a JPEG are examples of graphic image file types that contain bit maps. A bit map does not need to contain a bit of color-coded information for each pixel on every row. It only needs to contain information indicating a new color as the display scans along a row.
Bitmap image downsampled from an Inkscape vectorial image. In computer graphics, when the domain is a rectangle (indexed by two coordinates) a bitmap gives a way to store a binary image, that is, an image in which each pixel is either black or white (or any two colors). 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).
