4. _B_u_g__F_i_x_e_s
This chapter lists the bugs in version 1.0 through 1.1.2
that have been fixed in version of the Image Format
Library.
4.1 _A_p_p_e_n_d_i_n_g__i_f_l_R_G_B_P_a_l_e_t_t_e__i_m_a_g_e_s__t_o__T_I_F_F__f_i_l_e_s
When appending iflRGBPalette format image to TIFF file the
color map was sometimes garbled (also when switching between
sub-images). This has been corrected
4.2 _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.
4.3 _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.
4.4 _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.
4.5 _C_a_n_n_o_t__c_r_e_a_t_e__n_o_n_-_b_l_o_c_k_e_d__N_I_T_F__i_m_a_g_e_s
The NITF format does not allow for the creation of non-tiled
NITF images.
4.6 _N_I_T_F__v_a_r_i_a_b_l_e__l_e_n_g_t_h__f_i_e_l_d__h_a_n_d_l_i_n_g__i_s__i_n_c_o_r_r_e_c_t
The NITF foramt handler in IFL did not correctly handle
variable length fields and was missing some crucial API
entries. Additionally, the page count computation was
incorrect for separate images resulting in bad output
images.

4.7 _I_F_L_'_s__J_P_E_G__r_e_a_d_e_r__c_a_n_n_o_t__p_r_o_c_e_s_s__s_o_m_e__J_P_E_G__f_i_l_e_s
The JPEG reader in IFL 1.2 did not read some non-JFIF
formatted files. The rules for determining whether a file is
JPEG formatted have been relaxed in this release.
