_c_o_m_v_p_i_e_w provides a graphical interface to view an image and the
result of compressing the image with either sofware or hardware
JPEG while interactively setting the quality factor of the compressed
image. The size of the original image, the size of the compressed
image, and the compression ratio are displayed. As an option the
compresses/decompress cycle can be performed multiple times, with
the resulting image then displayed.
_c_o_m_p_v_i_e_w also provides panels to view the difference between the
original and the compressed image along with the mean squared error,
to provide information about the original image, and to view close-ups
of either image. These panels are updated automatically as the
quality factor is adjusted.
OOOOPPPPTTTTIIIIOOOONNNNSSSS
----qqqq _q_u_a_l_i_t_y
Initializes the quality factor to be _q_u_a_l_i_t_y.
----hhhhwwww Initializes the compressor to be hardware JPEG (default is
software JPEG).
----nnnnooooffffoooorrrrkkkk
Do not go into the background. By default, _c_o_m_p_v_i_e_w forks
itself to give control back to the shell.
