Cilostazol controls the symptoms of intermittent claudication but does not cure it. Although you may notice improvements in 2 to 4 weeks, it may take up to 12 weeks before you notice the full benefit (increased walking distance) of cilostazol.
Bit depth refers to the color information stored in an image. The higher the bit depth of an image, the more colors it can store. The simplest image, a 1 bit image, can only show two colors, black and white. That is because the 1 bit can only store one of two values, 0 (white) and 1 (black).
In some formats, the bit depth is not a multiple of 8. These formats are called packed formats, because the color channels in a pixel are not aligned to byte boundaries. For example, if the bit depths of 5, three color channels can be stored in 16 bits (including 1 bit of padding, to make pixels byte-aligned).
