		const float	tint )

cleanup_description()

std::string blender::ocio::cleanup_description

(

StringRef

description

)

Cleanup description making it possible to easily show in the interface as a tooltip.

This includes:

• Stripping all trailing line break character.
• Replacing all inner line break character with space.

get_version()

Version blender::ocio::get_version

(

)

Get OpenColorIO library version. When compiled without OpenColorIO library returns {0, 0, 0}.

Definition at line 11 of file version.cc.

Referenced by make_ocio_info().

source_comment_out_uniforms()

void blender::ocio::source_comment_out_uniforms

(

std::string &

source

)

Comment out all uniform statements. This avoids double declarations from the backend. This function modifies source in-place without adding extra characters. This means that statement like uniform vec3 pos; becomes //iform vec3 pos;.

Definition at line 9 of file source_processor.cc.

Referenced by TEST().

split_view_specific_look()

bool blender::ocio::split_view_specific_look	(	StringRef	look_name,
		StringRef &	view,
		StringRef &	ui_name )

Split the view-specific look name to a view name and look name for the interface.

Look is considered to be view-specific when it contains dash in its name. In this case the part of the look name is considered to be the name of the view the look is specific to.

If the look is not view-specific view is an empty string and ui name is the look name.

Returns true if the look name is view-specific.
