Image size to file size calculator

The file size calculator gives you the size of an uncompressed image file in bytes as calculated from the dimensions of the microscopic image. Depending on the file format the exact size will be somewhat larger due to overhead and storage of meta data. The calculator also calculates that.

An example

Dimensions of the original image data in pixels is specified as X x Y x Z x T x Ch.

From an image of 1024 x 1024 x 21 pixels (XYZ), 81 time frames, 2 channels, and saved as an 8bit file (1 byte), one can calculate:
1024 x 1024 x 21 x 81 x 2 x 1 = 3567255552 bytes.
Note, 1 Gigabyte (GB) is 230 bytes, thus 3567255552 bytes = 3567255552 / 230 GB = 3.3 GB.

At the same time, the image also consists of 3567255552 pixels and 308 of these images will fit in 1 Terapixel.
