Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

Summary: This is the first version of inverse color filter both GL and SW.
Test Plan:
1. Create filter_example with following .
efl_gfx_filter_program_set(image, "inverse_color ()", "inverse color");
2. Run.
./filter_example (Use ELM_ACCEL=gl for GL engine)

Without this, the prefix would get pointed to something like
/path/to/efl/build/share/evas, which is not a valid path when
building. That would cause the docs build to fail.
Summary:
This is detected by static analysis tool.
The variable last could be NULL when it is dereferenced.

This is very useful to specify precisely which kind of RGBA -> Alpha
conversion you want. If all you wanted was the alpha layer to use as a
mask, set this flag to true.

This might not be used as over two consecutive runs all the
same buffers should be used. But it could happen if some
parameters in the filter change (eg. blur radius).
Fixes major (GPU) memory leaks. Reuse mode is still leaking.
This will reuse existing buffers by resetting only the minimum
required in the filter context (also reused). Work in progress,
as the actual reuse is disabled for now.
This will be most useful in a special case, where a filter is
used in a window decoration, applied to a snapshot object.
Another optimization that might be wanted is passing a list
of update regions (from the proxy or snapshot).
The filters don't support the obscuring region yet, only some
of the high-level logic is implemented.
This corrects two things:
- the blur filter high-level logic, that lead to reusing some
temporary buffers which contained garbage;
- the versatile gl buffer implementation so that it now properly
switches between the RGBA_Image and the FBO content (yes, this
is insanely slow and inefficient... but it works and that was
the only point).
Alright, so this is a massive patch that is the result of
trying to get rid of unused or poorly implemented classes in
ector. Originally ector was meant to support VG but extend to
things like filters as well. At the moment, ector's design
makes it quite hard to plug in the filters.
For now I think it's easier to implement the GL support for
the filters directly in the engine, where I hope to interfere
as little as possible.
This massive patch keeps only the required minimum to support
a versatile gl buffer that can be mapped, drawn or rendered to (FBO).
It's extremely inefficient as it relies on glReadPixels and lots
of texture uploads, as well as conversions between ARGB and Alpha.
Another type of GL buffer is a wrap around an existing GL image,
but that one is read-only (map or draw: no write map, no FBO).
No, all the filters run fine, and the high-level implementation
(evas_filters.c) does not need to know whether the underlying engine
is SW or GL. One problem though appears with the blending or blurring
of some Alpha buffers, the colors are wrong.
This patch removes more lines than it adds so it must be good ;)
This is a preparation step for (experimental) textblock support.
Textblock objects won't have a single filter, and the buffer's
geometry wouldn't be that of of the object itself. Thus a few
internal APIs need to be reworked first.
Clang 3.9.0 told me:
warning: passing an object that undergoes default argument
promotion to 'va_start' has undefined behavior [-Wvarargs]
So I told it to shut up and changed Eina_Bool to int.
Note that edje_edit_state_external_param_set has the same issue.
I just ran my script (email to follow) to migrate all of the EFL
automatically. This commit is *only* the automatic conversion, so it can
be easily reverted and re-run.
This is a minor change, makes 'output' the default target for
the transform filter. This is consistent with all the other
filters. This is not exactly a bug fix but it doesn't break
compatibility with the earlier explicit form and improves the API
for 1.17.
In order to do that, avoid creating multiple Buffer instances
when pointing to the same proxy source. This fixes buffer.width
and buffer.height in Lua.
This fixes filters on Ubuntu 32 bits.
This was one hell of a weird bug to track down. Everything worked
like a charm on my 64 bit machines, but filters would simply fail
for no good reason: a safety check sees a NULL pointer when clearly
it was properly allocated.
Just after entering a function, the content of an RGBA_Image would
change, even though there was no memory write there. This made the
image data pointer NULL, and filters would fail miserably.
So I printed out the contents of the RGBA_Image, they changed. But
the memory itself had not changed. The size of the struct itself
had changed when jumping from one file to another! But its definition
had not! Non-sense!
Unless of course a system header file was included before config.h
and ino_t or off_t would switch between 32 and 64 bits...
@fix
The previous API supported stuff like "mask{'image1'}" but image1
is now not a valid buffer name, as it's only the proxy source name.
This patch fixes the buffer lookup.
