4. _B_u_g__F_i_x_e_s
This chapter lists the bugs in version 1.1 that have been
fixed in version of the Image Format Library.
4.1 _S_m_a_l_l _s_e_t_T_i_l_e _r_e_q_u_e_s_t _o_n _i_f_l_J_F_I_F_F_i_l_e _c_a_u_s_e_s _p_r_o_g_r_a_m
_a_b_o_r_t
Attempting to set a tile that is smaller than the entire
image on an empty JFIF file will result in a JPEG library
error.
4.2 _i_f_l_L_u_t::_g_e_t_O_r_i_g_i_n _a_n_d _i_f_l_L_u_t::_g_e_t_C_h_a_n _r_e_t_u_r_n _b_o_g_u_s
_r_e_s_u_l_t_s
When requesting the origin or channel for an invalid channel
(i.e., equal to the number of channels), these functions
would return a bogus value instead of NULL.
4.3 _Y_U_V__d_o_c_u_m_e_n_t_a_t_i_o_n__d_i_d__n_o_t__s_p_e_c_i_f_y__f_i_l_e__l_i_m_i_t_a_t_i_o_n_s
The iflYUV man page did not specify the required creation
method. This has been added with this release.
4.4 _i_f_l_J_F_I_F_F_i_l_e__l_e_a_k_s__m_e_m_o_r_y
When opening a new JFIF file, the iflJFIFFile object would
leak memory.
4.5 _N_o__i_n_i_t__i_f__i_f_l_L_u_t_:_:_s_e_t_D_o_m_a_i_n__w_i_t_h__m_i_n_=_=_m_a_x
When calling iflLut::setDomain with min == max, the scale
and bias values were not initialized. This could cause
problems for single bit palette images.
4.6 _C_o_l_o_r_m_a_p__g_e_n_e_r_a_t_e_d__i_n__c_o_r_r_e_c_t__f_o_r_m_a_t__f_o_r__T_I_F_F__f_i_l_e_s
In previous versions the colormap could be written to a TIFF
file in an incorrect format (not scaled to the full 16-bit
range expected). This is now fixed and a warning will be
issued when reading files with colormaps in the wrong
format.

4.7 _C_a_n_n_o_t__r_e_a_d__F_I_T__f_i_l_e_s__>__4_._2_G_B
The last revision of the FIT file reader could not read
files > 4.2GB (32 bit limitation). This limitation has been
removed with this release.
4.8 _G_I_F__s_u_p_p_o_r_t__e_x_p_a_n_d_e_d
Support animated and transparent GIFs was missing the
previous releases. These features have been added to this
release.
4.9 _i_f_l_R_a_w__d_o_e_s__n_o_t__r_e_c_o_g_n_i_z_e__n_o_n_-_i_n_t_e_g_r_a_l__r_a_n_g_e
iflRaw did not recognize non-integral range when specified
in the file name.
4.10 _i_f_l_T_I_F_F__c_o_m_p_l_a_i_n_s__a_b_o_u_t__u_n_k_n_o_w_n__t_a_g_s
When an unknown tag was encountered, iflTIFF would produce a
rather annoying warning message. This feature has been
removed.
4.11 _i_f_l_R_a_w__f_i_l_e_s__d_a_t_a_O_f_f_s_e_t__m_e_m_b_e_r__n_o_t__i_n_i_t_i_a_l_i_z_e_d
When an iflRaw file was created, the dataOffset member was
not initialized. This could cause the writes to the file at
random offsets.
