Greetings!
First, my personal thanks to you good folks who make
a wonderful tool like matplotlib available.
I am currently trying to build matplotlib-1.0.1 against
libpng1.5.1, and _png.cpp failed to compile. Apparently,
libpng's info_ptr is now opaque, so the code required
multiple changes of this nature:
-- _png.cpp.orig 2011-02-12 16:42:42.000000000 -0500
***************
*** 350,362 ****
png_set_sig_bytes(png_ptr, 8);
png_read_info(png_ptr, info_ptr);
! /*png_uint_32 width = info_ptr->width;*/
! /*png_uint_32 height = info_ptr->height;*/
! png_uint_32 width = png_get_image_width( png_ptr, info_ptr );
! png_uint_32 height = png_get_image_height( png_ptr, info_ptr );
! /*int bit_depth = info_ptr->bit_depth;*/
! int bit_depth = png_get_bit_depth( png_ptr, info_ptr );
// Unpack 1, 2, and 4-bit images
if (bit_depth < 8)
--- 350,359 ----
png_set_sig_bytes(png_ptr, 8);
png_read_info(png_ptr, info_ptr);
! png_uint_32 width = info_ptr->width;
! png_uint_32 height = info_ptr->height;
! int bit_depth = info_ptr->bit_depth;
// Unpack 1, 2, and 4-bit images
if (bit_depth < 8)

Sorry to be sending problems :-).
I suspect you have probably noticed this
already, but just in case I figured I'd send
a "head's up". Thanks!
Sincerely,
Mike Albert
