## 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 (eg. `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 usage example

Below is an illustrative example of how to use OpenGL to render to an object in Evas.

// Simple Evas_GL example

References evas_gl_context_destroy(), and evas_gl_surface_destroy().

EAPI Evas_GL_Config* evas_gl_config_new | ( | void |  | ) |

Allocates a new config object for the user to fill out.

Remarks
  As long as Evas creates a config object for the user, it takes care of the backward compatibility issue.

See also
  evas_gl_config_free

EAPI void evas_gl_config_free | ( | Evas_GL_Config * | cfg | ) |

Frees a config object created from evas_gl_config_new.

Parameters

  [in] | cfg | The configuration structure to free, it can not be accessed afterwards.

Remarks
  As long as Evas creates a config object for the user, it takes care of the backward compatibility issue.

See also
  evas_gl_config_new

EAPI Evas_GL_Surface* evas_gl_surface_create | ( | Evas_GL * | evas_gl,
|  | Evas_GL_Config * | cfg,

|  | int | h
| ) |  |

Creates and returns a new Evas_GL_Surface object for GL Rendering.

Parameters

  [in] | evas_gl | The given Evas_GL object
  [in] | cfg | The pixel format and configuration of the rendering surface
  [in] | w | The width of the surface
  [in] | h | The height of the surface

Returns
  The created GL surface object, otherwise `NULL` on failure

See also
  evas_gl_surface_destroy

References eina_list_prepend(), ERR, EVAS_GL_BAD_ALLOC, EVAS_GL_BAD_CONFIG, and EVAS_GL_BAD_PARAMETER.

EAPI Evas_GL_Surface* evas_gl_pbuffer_surface_create | ( | Evas_GL * | evas_gl,
|  | Evas_GL_Config * | cfg,
|  | int | w,
|  | int | h,

  The created GL surface object, otherwise `NULL` on failure

The surface must be released with evas_gl_surface_destroy.

If the color format in cfg is EVAS_GL_RGB_888 or EVAS_GL_RGBA_8888, then Evas will automatically generate a framebuffer attached to this PBuffer. Its properties can be queried using evas_gl_native_surface_get. If you want to attach an FBO yourself, or create a PBuffer surface only, please use the color format EVAS_GL_NO_FBO.

Creating a 1x1 PBuffer surface can be useful in order to call evas_gl_make_current() from another thread.

Note
  The attribute list can be terminated by EVAS_GL_NONE or 0. As of now, no special attributes are supported yet. Also, only EGL is supported at the moment of writing.

EAPI 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_gl | The 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.

See also
  Evas_GL_API
  evas_gl_context_api_get

EAPI 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 instanciated with evas_gl_context_version_create().

This function can be used to get the GL API for a 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_gl | The given Evas_GL object
  [in] | ctx | Specifies 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_context_version_create

Since
  1.12

References EVAS_GL_BAD_CONTEXT.

EAPI 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_gl | The 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.

EAPI Eina_Bool evas_gl_surface_query | ( | Evas_GL * | evas_gl,
|  | Evas_GL_Surface * | surface,
|  | int | attribute,
|  | void * | value
| ) |  |

Query a surface for its properties.

Parameters

  [in] | evas_gl | The current Evas_GL object
  [in] | surface | An Evas_GL_Surface surface to query
  [in] | attribute | Specifies the attribute to query.
  [out] | value | Returns the requested value (usually an int)

The currently accepted attributes are the following:

- EVAS_GL_WIDTH,
- EVAS_GL_HEIGHT,
- EVAS_GL_TEXTURE_FORMAT,
- EVAS_GL_TEXTURE_TARGET

Returns
  EINA_TRUE in case of success, EINA_FALSE in case of error.

EAPI 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_gl | The 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.

EAPI Evas_GL_Context* evas_gl_current_context_get | ( | Evas_GL * | evas_gl | ) |

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

Parameters

  [in] | evas_gl | The 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.

Since
  1.12

EAPI 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

  evas_gl | The 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.
