* move image content handlers to accomodate core build changesVincent Sanders2016-05-231-614/+0
|
* stop teh png image content handler directly reporting errors to usersVincent Sanders2016-04-291-2/+0
|
* stop content header dragging in so many other headersVincent Sanders2016-04-191-0/+1
|
* reduce content header interdependancyVincent Sanders2016-04-181-1/+1
|
* Fix size_t printf formattingVincent Sanders2016-03-171-1/+4
| | | | | | | The printf formatting for size_t is set in c99 as %zu but in windows it is %Iu this is solved by adding and inttypes style PRI macro for size_t This also uses this macro everywhere size_t is formatted.
* Change LOG() macro to be varadicVincent Sanders2015-05-281-6/+5
| | | | | | | | | | | | This changes the LOG macro to be varadic removing the need for all callsites to have double bracketing and allows for future improvement on how we use the logging macros. The callsites were changed with coccinelle and the changes checked by hand. Compile tested for several frontends but not all. A formatting annotation has also been added which allows the compiler to check the parameters and types passed to the logging.
* Fix the PNG handler crashing in low memory situations.Vincent Sanders2015-05-121-1/+13
| | | | | | | Obtaining a netsurf bitmap buffer may fail on some frontends (RISC OS especially) as the bitmap allocation is not performed until the buffer is requested. The PNG image handler failed to check for this when populating the row pointer structure.
* Move bitmap operations into an operation table.Vincent Sanders2015-04-131-22/+17
| | | | | | | The generic bitmap handlers provided by each frontend are called back from the core and therefore should be in an operation table. This was one of the very few remaining interfaces stopping the core code from being split into a library.

* Add Image cache and inegrate png and jpeg content handlersVincent Sanders2011-09-041-109/+264
| | | | | | | Current periodic cache clean algorithm is poor and requires replacing with something suitable (probably a segregated LRU) The speculative load algorithm is likewise poor and only uses the image size to make a decision. svn path=/trunk/netsurf/; revision=12720

The user of the content is now responsible for performing an initial reformat (sic) of the content before it can be redrawn. Purge width/height parameters from hlcache_handle_retrieve/content_convert/*_convert APIs. Fix up content handlers affected by the above change in semantics.
