- /* png_info is a structure that holds the information in a PNG file so |
- * that the application can find out the characteristics of the image. |
- * If you are reading the file, this structure will tell you what is |
- * in the PNG file. If you are writing the file, fill in the information |
- * you want to put into the PNG file, using png_set_*() functions, then |
- * call png_write_info(). |
- * |
- * The names chosen should be very close to the PNG specification, so |
- * consult that document for information about the meaning of each field. |
- * |
- * With libpng < 0.95, it was only possible to directly set and read the |
- * the values in the png_info_struct, which meant that the contents and |
- * order of the values had to remain fixed. With libpng 0.95 and later, |
- * however, there are now functions that abstract the contents of |
- * png_info_struct from the application, so this makes it easier to use |
- * libpng with dynamic libraries, and even makes it possible to use |
- * libraries that don't have all of the libpng ancillary chunk-handing |
- * functionality. In libpng-1.5.0 this was moved into a separate private |
- * file that is not visible to applications. |
- * |
- * The following members may have allocated storage attached that should be |
- * cleaned up before the structure is discarded: palette, trans, text, |
- * pcal_purpose, pcal_units, pcal_params, hist, iccp_name, iccp_profile, |
- * splt_palettes, scal_unit, row_pointers, and unknowns. By default, these |
- * are automatically freed when the info structure is deallocated, if they were |
- * allocated internally by libpng. This behavior can be changed by means |
- * of the png_data_freer() function. |
- * |
- * More allocation details: all the chunk-reading functions that |
- * change these members go through the corresponding png_set_* |
- * functions. A function to clear these members is available: see |
- * png_free_data(). The png_set_* functions do not depend on being |
- * able to point info structure members to any of the storage they are |
- * passed (they make their own copies), EXCEPT that the png_set_text |
- * functions use the same storage passed to them in the text_ptr or |
- * itxt_ptr structure argument, and the png_set_rows and png_set_unknowns |
- * functions do not make their own copies. |
