What's new in CPL 6.3.1
======================= - The release fixes the following bugs cpl_image_divide(), cpl_imagelist_divide(), cpl_imagelist_divide_image(), cpl_imagelist_collapse_create(): If no division by zero occurs, any bad pixel map in the input is not propagated to the result. cpl_error_set_message(): The macro is not properly defined in the absence of variadic macros (e.g. when compiling with -std=c89). What's new in CPL 6.3 ===================== - New functions and functionality cpl_vector_sum(): Sum the elements of a vector Two scaling filters for image filtering: CPL_FILTER_LINEAR_SCALE, CPL_FILTER_MORPHO_SCALE cpl_image_filter_mask(): Support the combination of CPL_FILTER_MEDIAN and CPL_BORDER_CROP and bad pixel(s) in the input Added support for table columns of type CPL_TYPE_LONG_LONG. - Deprecated functions cpl_frameset_get_frame(), cpl_frameset_get_frame_const(): Replaced by cpl_frameset_get_position() and cpl_frameset_get_position_const(). This fixes a flaw in the design of the old functions. New code should not use the old functions anymore, and old code should be ported as soon as possible, because it is intended to remove the old functions in version 7.0 - The release fixes the following bugs The interpolation profiles CPL_KERNEL_HAMMING and CPL_KERNEL_HANN are now multiplied by sinc(x), like CPL_KERNEL_LANCZOS. What's new in CPL 6.2 ===================== - New functions and functionality Support clang compiler: Stop CPLs usage of unsupported C99 operations cpl_test_get_tested() cpl_test_get_failed() CPL_WCS_REGEXP: Regexp matching the FITS keys used for WCS cpl_image_multiply(): Build with SSE2/3 enabled improves performance for complex pixel data. SSE2 is enabled by default on 64-bit operating systems. - The release fixes the following bugs cpl_image_get_fwhm(): gives wrong results cpl_matrix_dump(): Meaningless format string modification cpl_fit_image_gaussian(): No check of bad pixels in error map cpl_fit_image_gaussian(): Robustness issue cpl_imagelist_collapse_median_create(): Bad pixels ignored cpl_test_abs_complex(): Wrong number in message cpl_column_get_median(): Median of even number of samples ignores last sample cpl_matrix_get_median(): Ditto cpl_vector_get_median(): Ditto cpl_apertures_get_median(): Ditto cpl_wcs_platesol(): Ditto cpl_propertylist: Fixed handling of properties of type long long. - The release fixes the following documentation errors cpl_flux_get_noise_window(): Document randomness better cpl_image_get_median_dev_window(): Unclear doxygen cpl_bivector has wrong copy-pasted doxygen intro cpl_image_power_create(): Non-existing doxygen reference CPL_FILTER_LINEAR: Elaborate on the normalisation of the kernel CPL_FILTER_MORPHO: Ditto What's new in CPL 6.1 ===================== - New functions and functionality cpl_apertures_extract_mask() cpl_fits_get_mode() cpl_fits_set_mode() cpl_imagelist_unwrap() - The release fixes the following bugs cpl_apertures_new_from_image(): segfault on complex input cpl_flux_get_noise_window(): Incorrect error propagation cpl_image_move(): No support of complex pixels The caching of FITS files opened for reading did not support multi-threading cpl_plot_columns(), cpl_plot_vectors(): NULL-options not supported - The release fixes the following documentation errors Dropped documentation for the cpl_errorstate module Some internal and thus unavailable functions appeared in the documentation Usage example of cpl_error_set_message() clarified CPL_TYPE_COMPLEX was incorrecly documented from CPL 5.1.0 What's new in CPL 6.0 ===================== - New functions and functionality cpl_apertures_get_maxpos_x cpl_apertures_get_maxpos_y cpl_apertures_get_minpos_x cpl_apertures_get_minpos_y cpl_apertures_get_pos_x cpl_apertures_get_pos_y cpl_mask_load cpl_mask_load_window cpl_mask_save cpl_mask_threshold_image cpl_init Now supports a new, experimental and faster FITS I/O mode, which is enabled at run-time via the environment variable CPL_IO_MODE. Refer to the documentation of cpl_init() for more details. - Deprecated types and identifiers cpl_apertures_get_max_x Replace with cpl_apertures_get_pos_x cpl_apertures_get_max_y Replace with cpl_apertures_get_pos_y cpl_type_bpp Replace with cpl_type CPL_BPP_8_UNSIGNED Replace with CPL_TYPE_UCHAR CPL_BPP_16_SIGNED Replace with CPL_TYPE_SHORT CPL_BPP_16_UNSIGNED Replace with CPL_TYPE_USHORT CPL_BPP_32_SIGNED Replace with CPL_TYPE_INT CPL_BPP_IEEE_FLOAT Replace with CPL_TYPE_FLOAT CPL_BPP_IEEE_DOUBLE Replace with CPL_TYPE_DOUBLE No CPL_BPP macro should be used in a direct call to CFITSIO, this will no longer work. - Deprecated functions cpl_apertures_get_fwhm Replace with a loop over cpl_image_get_fwhm - No-cast image saving. cpl_image_save() and cpl_imagelist_save() now supports CPL_TYPE_UNSPECIFIED as file type, this ensures that the saving incurs no loss of information. - A new type - cpl_size - to be used for all size-related parameters in CPL. cpl_size is the largest possible signed integer type. The new type has its own format specifier, the string literal CPL_SIZE_FORMAT. - Functions with changed API (Parameter redeclaration to cpl_size*) Any call to one of the below functions must be modified accordingly cpl_apertures_extract cpl_apertures_extract_window cpl_array_get_maxpos cpl_array_get_minpos cpl_flux_get_bias_window cpl_flux_get_noise_window cpl_frameset_labelise

changed API (Parameter redeclaration to cpl_array*) Any call to one of the below functions must be modified accordingly (If a call passes NULL as the optional permutation parameter, then no change is required). cpl_matrix_decomp_lu cpl_matrix_solve_lu - Functions with changed API (Function or parameter redeclaration to cpl_size) Any call to one of the below functions must at least be recompiled, or better modified according to the new API cpl_apertures_get_bottom cpl_apertures_get_bottom_x cpl_apertures_get_centroid_x cpl_apertures_get_centroid_y cpl_apertures_get_flux cpl_apertures_get_left

to the new API cpl_dfs_save_image cpl_dfs_save_imagelist cpl_image_save cpl_imagelist_save - The release fixes the following bugs The use of an unnamed OpenMP critical section cpl_init() segfaults with OpenMP if OMP_NUM_THREADS is undefined cpl_fit_imagelist_polynomial() SIGABRT on complex input cpl_image_filter(), cpl_image_filter_mask(): Error handling bug cpl_imagelist_collapse_sigclip_create(): Nothing is rejected cpl_image_get_complex(): NULL input dereferenced cpl_geom_img_offset_combine(): Input imagelist is now const - The release fixes the following documentation errors Missing doxygen for cpl_stats modes, CPL_STATS_* cpl_dfs_save_propertylist: applist is no longer optional cpl_dfs_save_imagelist: applist is no longer optional cpl_dfs_save_table: applist is no longer optional What's new in CPL 5.2 ============================================ - New functions in CPL 5.2: cpl_array_cast() cpl_mask_filter() cpl_plot_mask() cpl_image_unset_bpm() - New functionality: cpl_table_cast_column() allows casting from array columns of depth one to plain columns, and viceversa. - Bug fixes: Casting table columns of type array to columns of type array. cpl_table_save() returns in case of ILLEGAL_OUTPUT caused by zero depth integer array columns; allocate empty integer arrays in case they must be written to file. cpl_image_new_from_accepted(): Older versions would force the creation of an empty bad pixel map in any image in the input image list, that did not already have one. cpl_detector_interpolate_rejected(): Older versions would use wrong interpolation values at the image border. cpl_wcs_platesol(): All previous versions computes a wrong solution. cpl_bivector_interpolate_linear(): Versions from 4.2.0 interpolates the first value wrongly. cpl_stats_dump(): Older versions do not dump median deviation cpl_geom_img_offset_combine(): Older versions would use the error code CPL_ERROR_ILLEGAL_OUTPUT instead of CPL_ERROR_DATA_NOT_FOUND. cpl_dfs_update_product_header(): Older versions would not work if the system macro L2_CACHE_BYTES was defined to 0. cpl_end(): Free any memory allocated internally by FFTW. cpl_vector_find(): Fail on non-sorted vector elements. - Deprecated functions cpl_mask_closing(): Use cpl_mask_filter() instead cpl_mask_opening(): Use cpl_mask_filter() instead cpl_mask_erosion(): Use cpl_mask_filter() instead cpl_mask_dilation(): Use cpl_mask_filter() instead - Doc fixes: Specify that all arrays in a column must have same length Complete doc of cpl_table_set_array() Fix wrong LaTex code in cpl_fit_image_gaussian() doc. Document that cpl_geom_img_offset_saa() handles bad pixels. The pixel indexing convention ((1,1) for lower left) is documented. The deprecated CPL functions are clearly documented as such. What's new in CPL 5.1 ============================================ - New functions in CPL 5.1 cpl_array_is_valid cpl_array_dump_structure cpl_array_dump cpl_fit_image_gaussian cpl_flux_get_bias_window cpl_mask_dump_window cpl_propertylist_append_property cpl_propertylist_prepend_property cpl_propertylist_insert_property cpl_propertylist_insert_after_property cpl_test_array_abs cpl_test_eq_error cpl_test_eq_ptr cpl_test_get_cputime cpl_test_get_walltime cpl_test_imagelist_abs cpl_test_noneq_ptr cpl_test_vector_abs - New function modes in CPL 5.1. CPL_IO_APPEND - Deprecated functions cpl_image_fit_gaussian: Use cpl_fit_image_gaussian instead. - Other Changes CPL functions with complex types in their API are only available (declared) when the CPL-based application #include's <complex.h>. The functions effected by this are: cpl_image_wrap_double_complex cpl_image_wrap_float_complex cpl_image_get_complex cpl_image_set_complex cpl_image_get_data_double_complex cpl_image_get_data_double_complex_const cpl_image_get_data_float_complex cpl_image_get_data_float_complex_const - Bug fixes The filtering mode CPL_FILTER_STDEV had a bug which could cause wrong outputs. This has been fixed. - Known Problems CPL release 5.1 (and all releases back to and including 4.1) has a documentation bug in both cpl_image_turn() and cpl_mask_turn(). The orientation of the rotation is opposite of what is stated in the documentation. Given a rotation of 1, the function will rotate by 90 degrees clockwise and given a rotation of -1 the function will rotate by 90 degrees counterclockwise. The documentation of rotation by any odd number is similarly wrong. The documentation of rotation by any even number is unaffected by the error. What's new in CPL 5.0 ============================================ - Deprecated functions. A number of functions are now deprecated. The deprecated functions will remain in CPL 5.X. The deprecated functions are: cpl_fits_get_nb_extensions cpl_fits_get_extension_nb cpl_image_filter_median cpl_image_filter_linear cpl_image_filter_stdev cpl_image_filter_morpho cpl_msg_progress cpl_polynomial_fit_1d_create cpl_polynomial_fit_2d_create cpl_vector_new_lss_kernel cpl_vector_convolve_symmetric - Warnings of use of deprecated functions. Using gcc to compile code using the above mentioned functions will lead to compiler warnings. These warnings can be suppressed with -Wno-deprecated-declarations. This gcc option can be applied with ./configure CFLAGS=-Wno-deprecated-declarations . - Functions with changed API cpl_dfs_save_image cpl_dfs_save_table cpl_dfs_save_propertylist cpl_dfs_save_imagelist cpl_dfs_setup_product_header cpl_geom_img_offset_saa cpl_propertylist_erase_regexp cpl_image_get_bpm_const cpl_polynomial_shift_1d cpl_imagelist_collapse_sigclip_create - How to replace deprecated functions cpl_fits_get_nb_extensions: Replace with cpl_fits_count_extensions cpl_fits_get_extension_nb: Replace with cpl_fits_find_extension cpl_image_filter_median: cpl_image * a = cpl_image_filter_median(b, k) can be replaced by int nx = cpl_image_get_size_x(b); int ny = cpl_image_get_size_y(b); int type = cpl_image_type(b); cpl_image * a = cpl_image_new(nx, ny, type); cpl_image_filter_mask(a, b, m, CPL_FILTER_MEDIAN, CPL_BORDER_FILTER); - where m is a cpl_mask with a CPL_BINARY_1 whereever k has a 1.0. cpl_image_filter_stdev: Same as for cpl_image_filter_median, but with CPL_FILTER_STDEV cpl_image_filter_linear: cpl_image * a = cpl_image_filter_linear(b, k) can be replaced by int nx = cpl_image_get_size_x(b); int ny = cpl_image_get_size_y(b); int type = cpl_image_type(b); cpl_image * a = cpl_image_new(nx, ny, type); cpl_image_filter(a, b, k, CPL_FILTER_LINEAR, CPL_BORDER_FILTER); - where m is the cpl_matrix with the weights. cpl_image_filter_morpho: Same as for cpl_image_filter_linear, but with CPL_FILTER_MORPHO cpl_polynomial_fit_1d_create: cpl_polynomial * fit1d = cpl_polynomial_fit_1d_create(x_pos, values, degree, mse); can be replaced by cpl_polynomial * fit1d = cpl_polynomial_new(1); cpl_matrix * samppos = cpl_matrix_wrap(1, cpl_vector_get_size(x_pos), cpl_vector_get_data(x_pos)); cpl_vector * fitresidual = cpl_vector_new(cpl_vector_get_size(x_pos)); cpl_polynomial_fit(fit1d, samppos, NULL, values, NULL, CPL_FALSE, NULL, °ree); cpl_vector_fill_polynomial_fit_residual(fitresidual, values, NULL, fit1d, samppos, NULL); cpl_matrix_unwrap(samppos); mse = cpl_vector_product(fitresidual, fitresidual) / cpl_vector_get_size(fitresidual); cpl_vector_delete(fitresidual); cpl_polynomial_fit_2d_create: Similar to 1D, and the samppos matrix must have two rows with copies of the two vectors in the x_pos bivector. cpl_msg_progress: This function has no CPL 5.X equivalent cpl_vector_new_lss_kernel: This function has no CPL 5.X equivalent cpl_vector_convolve_symmetric: This function has no CPL 5.X equivalent - How to change the calls to functions with new prototypes cpl_dfs_save_image(allframes, parlist, usedframes, image, bpp, recipe, procat, applist, remregexp, pipe_id, filename); can be replaced with: cpl_propertylist * prolist = applist ? cpl_propertylist_duplicate(applist) : cpl_propertylist_new(); cpl_propertylist_append_string(prolist, CPL_DFS_PRO_CATG, procat); cpl_dfs_save_image(allframes, NULL, parlist, usedframes, NULL, image, bpp, recipe, prolist, remregexp, pipe_id, filename); cpl_propertylist_delete(prolist); cpl_dfs_save_table: See cpl_dfs_save_image cpl_dfs_save_propertylist: See cpl_dfs_save_image cpl_dfs_save_imagelist: See cpl_dfs_save_image cpl_dfs_setup_product_header: Append a NULL pointer to the argument list, cpl_geom_img_offset_saa: : Append two NULL pointers to the argument list, cpl_propertylist_erase_regexp: In case of error, the return value is now -1 instead of 0. cpl_image_get_bpm_const: The function will now return NULL if the image does not have a bad pixel map, meaning no pixels are bad. If the input image is guaranteed to have a bad pixel map, then no change is needed. Otherwise, if the bad pixel map must be modified the call should be replaced with cpl_image_get_bpm(). If the bad pixel map will not be modified i.e. only read, then a NULL value indicates that no pixels are bad. This can be used both to determine if a pixel map exists for the image, and to choose faster methods when no pixels are bad. cpl_polynomial_shift_1d: Insert a 0 between the current two parameters. cpl_imagelist_collapse_sigclip_create: Extend the argument list with 0.0, 1.0, 1, NULL. - New functions in CPL cpl_image_filter_xyz cpl_fits_count_extensions cpl_fits_find_extension cpl_array_get_max cpl_array_get_min cpl_array_get_maxpos cpl_array_get_minpos cpl_array_get_mean cpl_array_get_median cpl_array_get_stdev cpl_array_extract cpl_array_insert_window cpl_array_erase_window cpl_array_insert cpl_array_add cpl_array_subtract cpl_array_multiply cpl_array_divide cpl_array_add_scalar cpl_array_subtract_scalar cpl_array_multiply_scalar cpl_array_divide_scalar cpl_array_set_size cpl_image_rebin cpl_image_fill_jacobian cpl_image_fill_jacobian_polynomial cpl_array_power cpl_array_abs cpl_array_logarithm cpl_array_exponential cpl_table_where_selected cpl_table_set_column_savetype cpl_image_wrap_double_complex cpl_image_wrap_float_complex cpl_image_get_data_double_complex cpl_image_get_data_double_complex_const cpl_image_get_data_float_complex cpl_image_get_data_float_complex_const cpl_image_get_complex cpl_image_set_complex - New types CPL_TYPE_DOUBLE_COMPLEX and CPL_TYPE_FLOAT_COMPLEX These 2 types are now supported for a limited set of image functions: cpl_image_new cpl_image_add cpl_image_subtract cpl_image_multiply cpl_image_divide cpl_image_add_create cpl_image_subtract_create cpl_image_multiply_create cpl_image_divide_create cpl_image_cast cpl_image_fill_rejected cpl_image_dump_window cpl_image_extract The purpose of the inclusion of these new types is to ease operations with the FFTW library on CPL images. With these new types, there is no need to remap the input pixel buffer before calling FFTW. Example (with FFTW 2.1.5): cpl_image * in = cpl_image_new(nx, ny, CPL_TYPE_FLOAT); cpl_image * out = cpl_image_new(nx, ny, CPL_TYPE_FLOAT_COMPLEX); float * in_b = cpl_image_get_data_float(in); float complex * out_b = cpl_image_get_data_float_complex(out); fftwnd_plan rp = rfftw2d_create_plan(nx, ny, FFTW_FORWARD, FFTW_ESTIMATE); cpl_image_fill_noise_uniform(in, 0.0, 10.0); rfftwnd_real_to_complex(rp, 1, (fftw_real *)in_b, 1, nx * ny, (fftw_complex *)out_b, 1, nx * ny); my_frequency_processing(out); |
