Evas GL error codes

These are the possible return values of evas_gl_error_get.

The values are the same as EGL error codes - EGL_SUCCESS.

Some of the values may be set directly by Evas GL when an obvious error was detected (e.g. NULL pointers or invalid dimensions), otherwise Evas GL will call the backend's GetError() function and translate to a valid EVAS_GL_ error code.

Detailed Description

This group discusses the functions that are used to do OpenGL rendering on Evas.

Evas allows you to use OpenGL to render to specially set up image objects (which act as render target surfaces).

◆ evas_gl_api_get()

EVAS_API Evas_GL_API * evas_gl_api_get ( Evas_GL evas_gl)

Gets the API for rendering using OpenGL.

This returns a structure that contains all the OpenGL functions you can use to render in Evas. These functions consist of all the standard OpenGL-ES2.0 functions and any additional ones that Evas has decided to provide. This means that if you have your code ported to OpenGL-ES2.0, it is going to be easy to render to Evas.

Parameters
[in]evas_glThe given Evas_GL object
Returns
The API to use
Note
This function will always return an OpenGL-ES 2.0 API, please use evas_gl_context_api_get instead to get an OpenGL-ES 1.1 set of APIs.

◆ evas_gl_context_api_get()

EVAS_API Evas_GL_API * evas_gl_context_api_get ( Evas_GL evas_gl,
Evas_GL_Context ctx 
)

Gets the API for rendering using OpenGL with non standard contexts.

This function is similar to evas_gl_api_get but takes an extra Evas GL context argument as it is used to get the real API used by special contexts, that have been instantiated with evas_gl_context_version_create().

This function can be used to get the GL API for an OpenGL-ES 1.1 context. When using OpenGL-ES 1.1, applications should always use evas_gl_context_api_get and never call evas_gl_api_get (this will always return a OpenGL-ES 2+ API).

Parameters
[in]evas_glThe given Evas_GL object
[in]ctxSpecifies which context to use, based on this, Evas GL will return a 1.1- or a 2.0-compatible OpenGL-ES API.
Returns
The API to use. Only the available function pointers will be set in the structure. All the non compatible functions or unsupported extension function pointers will be set to NULL.

◆ evas_gl_rotation_get()

EVAS_API int evas_gl_rotation_get ( Evas_GL evas_gl)

Get the current rotation of the view, in degrees.

This function should be called in order to properly handle the current rotation of the view. It will always return 0 unless the option EVAS_GL_OPTIONS_CLIENT_SIDE_ROTATION has been set.

Indeed, in case of direct rendering to the back buffer, the client application is responsible for properly rotating its view. This can generally be done by applying a rotation to a view matrix.

Parameters
[in]evas_glThe current Evas_GL object
Note
The returned value may not be the same as the window rotation, for example if indirect rendering is used as a fallback, or if the GPU supports transparent rotation of the buffer during swap.
Returns
0, 90, 180 or 270 depending on the Evas canvas' orientation.

EVAS_API Eina_Bool evas_gl_surface_query ( Evas_GL evas_gl,

)

Query a surface for its properties.

Parameters
[in]evas_glThe current Evas_GL object
[in]surfaceAn Evas_GL_Surface surface to query
[in]attributeSpecifies the attribute to query.
[out]valueReturns the requested value (usually an int)

The currently accepted attributes are the following:

◆ evas_gl_error_get()

EVAS_API int evas_gl_error_get ( Evas_GL evas_gl)

Returns the last error of any evas_gl function called in the current thread.

Initially, the error is set to EVAS_GL_SUCCESS. A call to evas_gl_error_get resets the error to EVAS_GL_SUCCESS.

Parameters
[in]evas_glThe given Evas_GL object
Returns
EVAS_GL_SUCCESS in case of no error, or any other EVAS_GL error code.

Since Evas GL is a glue layer for GL imitating EGL, the error codes returned have a similar meaning as those defined in EGL, so please refer to the EGL documentation for more information about the various error codes.

Note
Evas GL does not specify exactly which error codes will be returned in which circumstances. This is because different backends may behave differently and Evas GL will try to give the most meaningful error code based on the backend's error. Evas GL only tries to provide some information, so an application can not expect the exact same error codes as EGL would return.

◆ evas_gl_current_context_get()

Returns the Evas GL context object in use or set by evas_gl_make_current.

Parameters
[in]evas_glThe given Evas_GL object
Returns
The current context for the calling thread, or NULL in case of failure and when there is no current context in this thread.

EVAS_API Evas_GL_Surface * evas_gl_current_surface_get ( Evas_GL evas_gl)

Returns the Evas GL surface object in use or set by evas_gl_make_current.

Parameters
[in]evas_glThe given Evas_GL object
Returns
The current surface for the calling thread, or NULL in case of failure and when there is no current surface in this thread.

This can be used to get a handle to the current surface, so as to switch between contexts back and forth. Note that the OpenGL driver may stall when doing so.

◆ evas_gl_current_evas_gl_get()

EVAS_API Evas_GL * evas_gl_current_evas_gl_get ( Evas_GL_Context **  context,
Evas_GL_Surface **  surface 
)

Get current Evas GL.

Parameters
[out]contextOptional return value for the current context
[out]surfaceOptional return value for the current surface
Returns
The current Evas GL, i.e. the last Evas GL passed to evas_gl_make_current

Note
This can be used to restore a previous context, for instance if you are writing a library that needs to work transparently with Evas GL, and may not have control over the other Evas GL objects.
