it is now possible to build text-freetype2 on linux if you comment out a return() otherwise there would have been an error
Also i made the word iconv in find_package lower case, to match the APPLE cmake code
This changes the font plugin from using a font file to using a specific
installed system font, which is searched for on each specific system and
associated with the font file. It now uses a font property instead of a
path property, and font size has been removed because the font property
now handles that.
When the module is first loaded, it will build up a list of system fonts
in order to be usable by Freetype. It was quite painful to program this
because font files can contain multiple localized versions of their face
names, and then there was the issue where windows likes to mangle
custom style types to the font name. Regardless, it all seems to have
worked out pretty well.
Minor issues:
- Truetype/Opentype fonts sometimes do not automatically have
italic and/or bold styles available, it seems that the system applies
transformations manually in those cases. We don't do this yet,
however, so right now a user might select a font with italic/bold
only to discover that italic/bold doesn't always work. Not entirely
sure what to do about this yet. There's probably a freetype function
to do something like that somehow,
This also requires that iconv be used for non-windows systems to be able
to look up localized font names within font files. Windows will use
the win32 API and code page IDs to translate font names.
Adds the following function:
------------------------------
obs_properties_add_font
This function creates a 'font' property to allow selection of a system
font. Implementation by the UI should treat the setting as an obs_data
sub-object with four sub-items:
- face: face name (string)
- style: style name (string)
- size: size (integer)
- flags: font flags (integer)
'flags' can be any combination of the following values:
- OBS_FONT_BOLD
- OBS_FONT_ITALIC
- OBS_FONT_UNDERLINE
- OBS_FONT_STRIKEOUT
The alpha source and destination blend values were always being set to
one and zero, when they should have been set to the same as the color
values. This caused the alpha of the source texture to always overwrite
the alpha of the destination texture, rather than apply the blend
function upon it. Needless to say that it seriously screwed up the
render target if you rendered something with alpha on it.
Thanks to paibox for pointing this issue out and yelling at me to fix
it. I apologize for not getting to this sooner.
This moves some functions that are generic to a separate source
file. While doing so the api to those functions was improved to
be more generic and not depend on knowledge about the internal
structure of the plugin.
API functions added:
-----------------------------------------------
obs_output_set_preferred_size
obs_output_get_width
obs_output_get_height
obs_encoder_set_scaled_size
obs_encoder_get_width
obs_encoder_get_height
These functions allow for easier means of setting a custom resolution on
an output or encoder.
If an output uses an encoder and you set the preferred width/height
using the output, then the output will attempt to set the scaled
width/height for the encoder it's currently using.
Outputs and encoders now should use these functions to determine the
width/height of the raw frame data instead of using the video-io
functions.
This is sort of hard to explain: the scale_video_output function was
overwriting the current frame. If scaling was disabled, it would do
nothing, and return success, and all would be well. If it was enabled,
it would then call the scaler, and then replace the contents of the
'data' function parameter with the scaled frame data. The problem with
this is that I was passing video_output::cur_frame directly, which
overwrites its previous value with the scaled frame data. Then if
cur_frame was not updated on time, it would end up trying to scale the
previously scaled image, if that makes sense. it would call the video
scaler with the same from for both the source and destination.
So the simple fix was to simply use a local variable and pass that in as
a parameter to prevent this bug from occurring.
For the sake of consistency, renamed these two functions to include
_value at the end so they are consistent.
Renamed: To:
-------------------------------------------------------
obs_data_has_default obs_data_has_default_value
obs_data_has_autoselect obs_data_has_autoselect_value
obs_data_item_has_default obs_data_item_has_default_value
obs_data_item_has_autoselect obs_data_item_has_autoselect_value
Instead of having functions like obs_signal_handler() that can fail to
properly specify their actual intent in the name (does it signal a
handler, or does it return a signal handler?), always prefix functions
that are meant to get information with 'get' to make its functionality
more explicit.
Previous names: New names:
-----------------------------------------------------------
obs_audio obs_get_audio
obs_video obs_get_video
obs_signalhandler obs_get_signal_handler
obs_prochandler obs_get_proc_handler
obs_source_signalhandler obs_source_get_signal_handler
obs_source_prochandler obs_source_get_proc_handler
obs_output_signalhandler obs_output_get_signal_handler
obs_output_prochandler obs_output_get_proc_handler
obs_service_signalhandler obs_service_get_signal_handler
obs_service_prochandler obs_service_get_proc_handler
API Removed:
- graphics_t obs_graphics();
Replaced With:
- void obs_enter_graphics();
- void obs_leave_graphics();
Description:
obs_graphics() was somewhat of a pointless function. The only time
that it was ever necessary was to pass it as a parameter to
gs_entercontext() followed by a subsequent gs_leavecontext() call after
that. So, I felt that it made a bit more sense just to implement
obs_enter_graphics() and obs_leave_graphics() functions to do the exact
same thing without having to repeat that code. There's really no need
to ever "hold" the graphics pointer, though I suppose that could change
in the future so having a similar function come back isn't out of the
question.
Still, this at least reduces the amount of unnecessary repeated code for
the time being.
Changed:
- obs_source_gettype
To:
- enum obs_source_type obs_source_get_type(obs_source_t source);
- const char *obs_source_get_id(obs_source_t source);
This function was inconsistent for a number of reasons. First, it
returns both the ID and the type of source (input/transition/filter),
which is inconsistent with the name of "get type". Secondly, the
'squishy' naming convention which has just turned out to be bad
practice and causes inconsistencies. So it's now replaced with two
functions that just return the type and the ID.
Prefix with obs_ for the sake of consistency
Renamed enums:
- order_movement (now obs_order_movement)
Affected functions:
- obs_source_filter_setorder
- obs_sceneitem_setorder
Renamed functions:
- obs_source_getframe (rename to obs_source_get_frame)
- obs_source_releaseframe (rename to obs_source_release_frame)
For the sake of consistency and helping to get rid of the "squishy
function name" issue
