5. _K_n_o_w_n__P_r_o_b_l_e_m_s__a_n_d__W_o_r_k_a_r_o_u_n_d_s
This chapter lists the known problems in version 3.0 of the
ImageVision Library and, where known, ways to work around
them.
5.1 _W_r_i_t_i_n_g__S_G_I__F_i_l_e_s__W_i_t_h__A_r_b_i_t_r_a_r_y__M_i_n_/_M_a_x__V_a_l_u_e_s
Silicon Graphics' classic ._r_g_b format does not support
setting of arbitrary min and max values. Use TIFF format if
you wish to generate an image with arbitrary min and max
pixel values.
5.2 _R_e_a_d_i_n_g__C_o_r_r_u_p_t__R_L_E_-_E_n_c_o_d_e_d__S_G_I_-_F_o_r_m_a_t__F_i_l_e_s
Reading in a truncated or otherwise corrupt RLE-encoded
SGI-format file can cause an ImageVision application to core
dump.
5.3 _I_L__M_o_n_i_t_o_r__C_a_n__A_f_f_e_c_t__P_r_o_g_r_a_m__T_e_r_m_i_n_a_t_i_o_n
When running the ILmonitor mp-enabled and with IL_MONITOR
set to 2, if you exit the monitor while the application is
still running, the application will not terminate as its
threads linger.
5.4 _I_L__M_o_n_i_t_o_r__T_o_t_a_l__C_a_c_h_e__S_i_z_e__D_i_s_p_l_a_y
When invoked by setting the environment variable IL_MONITOR
= 2, the total cache size display on the main IL monitor
window doesn't update properly when there are no image
monitor windows open. Open an image monitor window to get
it to update.
5.5 _i_l_C_h_a_r__d_a_t_a__t_y_p_e__n_o_t__s_u_p_p_o_r_t_e_d
Most IL operators will give incorrect results for the ilChar
data type. Converting to ilShort is the work around.
