Hi,

Is there any way to tell the size in bytes of a RasterImage object without writing it to the filesystem?

Thanks

Matt.

Use this equation to calculate the size of an image in memory:

ImageWidth * ImageHeight * Bpp

Note that Bpp in this equation is Bytes per pixel, this means that you would use the bpp (bits per pixel) divided by 8:

ImageWidth * ImageHeight * (bpp / 8)

However, there is no way to calculate the size of a file on disk because of the possible compression algorithms used.

Note:
Because of byte alignment, the size might not be given exactly by the above formula in all cases.
