5. _K_n_o_w_n__P_r_o_b_l_e_m_s
This chapter lists the known problems in release 3.1.1 of
the ImageVision Tools.
5.1 _i_m_g_t_c_l__w_i_l_l__a_b_o_r_t__o_n__s_o_m_e__s_c_r_i_p_t__e_r_r_o_r_s
The error checking in imgtcl is incomplete. It is fairly
easy to construct a bogus script that will abort imgtcl. In
particular, be careful about referencing undefined
variables.
5.2 _i_m_g_v_i_e_w__c_a_n__f_a_i_l__w_i_t_h__B_a_d_A_l_l_o_c__o_n__R_E
On Onyx/RealityEngine systems running Irix 6.2 it is
possible for imgview to exit with a "BadAlloc" error from
the X server. This sometimes occurs when the ImageVision
Library attempts to allocate more pbuffers to accelerate
processing if all of the processing operations are enabled.
The workaround is to disable acceleration (from the 'Edit'
menu on the Processing panel) if this occurs.
