- 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.

-
- 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.
-
-
- 4.8 _B_l_a_c_k__f_i_r_s_t__t_i_l_e__i_n__w_r_i_t_t_e_n__P_P_M__f_i_l_e
-
- Format handler doesn't handle initial getpage correctly
- (zeroing it for new files). The result is a hole in the
- file.
-
-
- 4.9 _S_o_m_e__I_F_L__r_e_a_d_e_r_s__d_o__n_o_t__p_r_o_v_i_d_e__f_o_r__a_l_l__f_o_r_m_a_t_s
-
- Several IFL file readers, specifically PNG and YUV were not
- fully supported. Also, float tags were not correctly
- handled.
