EAPI Eina_Bool evas_map_alpha_get (const Evas_Map * m)

get the alpha flag for map rendering This gets the alph flag for map rendering.

Parameters:

m map to get the alpha from. Must not be NULL.

EAPI void evas_map_alpha_set (Evas_Map * m, Eina_Bool enabled)

Set the alpha flag for map rendering. This sets alpha flag for map rendering. If the object is a type that has its own alpha settings, then this will take precedence. Only image objects have this currently. Fits stops alpha blending of the map area, and is useful if you know the object and/or all sub-objects is 100% solid.

Parameters:

m map to modify. Must not be NULL. enabled enable or disable alpha map rendering

EAPI Evas_Map* evas_map_dup (const Evas_Map * m)

Copy a previously allocated map. This makes a duplicate of the m object and returns it.

Parameters:

m map to copy. Must not be NULL.

Returns:

newly allocated map with the same count and contents as m.

EAPI void evas_map_free (Evas_Map * m)

Free a previously allocated map. This frees a givem map m and all memory associated with it. You must NOT free a map returned by evas_object_map_get() as this is internal.

Parameters:

m map to free.

EAPI Evas_Map* evas_map_new (int count)

Create map of transformation points to be later used with an evas object. This creates a set of points (currently only 4 is supported. no other number for count will work). That is empty and ready to be modified with evas_map calls.

Parameters:

count number of points in the map. *

Returns:

a newly allocated map or NULL on errors.

EAPI void evas_map_point_color_get (const Evas_Map * m, int idx, int * r, int * g, int * b, int * a)

Get the color set on a vertex in the map. This gets the color set by evas_map_point_color_set() on the given vertex of the map.

Parameters:

m map to get the color of the vertex from. idx index of point get. Must be smaller than map size. r pointer to red return g pointer to green return b pointer to blue return a pointer to alpha return (0 - 255)

evas_map_point_coord_set()
evas_object_map_set()

EAPI void evas_map_point_color_set (Evas_Map * m, int idx, int r, int g, int b, int a)

Set the color of a vertex in the map. This sets the color of the vertex in the map. Colors will be linearly interpolated between vertex points through the map. Color will multiply the 'texture' pixels (like GL_MODULATE in OpenGL). The default color of a vertex in a map is white solid (255, 255, 255, 255) which means it will have no affect on modifying the texture pixels.

Parameters:

m map to change the color of. idx index of point to change. Must be smaller than map size. r red (0 - 255) g green (0 - 255) b blue (0 - 255) a alpha (0 - 255)

EAPI void evas_map_point_coord_get (const Evas_Map * m, int idx, Evas_Coord * x, Evas_Coord * y, Evas_Coord * z)

Get the map point's coordinate. This returns the coordinates of the given point in the map.

Parameters:

m map to query point. idx index of point to query. Must be smaller than map size. x where to return the X coordinate. y where to return the Y coordinate. z where to return the Z coordinate.

EAPI void evas_map_point_coord_set (Evas_Map * m, int idx, Evas_Coord x, Evas_Coord y, Evas_Coord z)

Change the map point's coordinate. This sets the fixen point's coordinate in the map. Note that points describe the outline of a quadrangle and are ordered either clockwise or anit-clock-wise. It is suggested to keep your quadrangles concave and non-complex, though these polygon modes may work, they may not render a desired set of output. The quadrangle will use points 0 and 1 , 1 and 2, 2 and 3, and 3 and 0 to describe the edges of the quandrangle.

The X and Y and Z coordinates are in canvas units. Z is optional and may or may not be honored in drawing. Z is a hint and does not affect the X and Y rendered coordinates. It may be used for calculating fills with perspective correct rendering.

Remember all coordinates are canvas global ones like with move and reize in evas.

Parameters:

m map to change point. Must not be NULL. idx index of point to change. Must be smaller than map size. x Point X Coordinate y Point Y Coordinate z Point Z Coordinate hint (pre-perspective transform)

EAPI void evas_map_point_image_uv_get (const Evas_Map * m, int idx, double * u, double * v)

Get the map point's U and V texture source points. This returns the texture points set by evas_map_point_image_uv_set().

Parameters:

m map to query point. idx index of point to query. Must be smaller than map size. u where to write the X coordinate within the image/texture source v where to write the Y coordinate within the image/texture source

EAPI void evas_map_point_image_uv_set (Evas_Map * m, int idx, double u, double v)

Change the map point's U and V texture source point. This sets the U and V coordinates for the point. This determines which coordinate in the source image is mapped to the given point, much like OpenGL and textures. Notes that these points do select the pixel, but are double floating point values to allow for accuracy and sub-pixel selection.

Parameters:

m map to change the point of. idx index of point to change. Must be smaller than map size. u the X coordinate within the image/texture source v the Y coordinate within the image/texture source

Parameters:

m map to get the smooth from. Must not be NULL.

EAPI void evas_map_smooth_set (Evas_Map * m, Eina_Bool enabled)

Set the smoothing for map rendering. This sets smoothing for map rendering. If the object is a type that has its own smoothing settings, then both the smooth settings for this object and the map must be turned off. By default smooth maps are enabled.

Parameters:

m map to modify. Must not be NULL. enabled enable or disable smooth map rendering

EAPI void evas_map_util_3d_lighting (Evas_Map * m, Evas_Coord lx, Evas_Coord ly, Evas_Coord lz, int lr, int lg, int lb, int ar, int ag, int ab)

Perform lighting calculations on the given Map. This is used to apply lighting calculations (from a single light source) to a given map. The R, G and B values of each vertex will be modified to reflect the lighting based on the lixth point coordinates, the light color and the ambient color, and at what angle the map is facing the light source. A surface should have its points be declared in a clockwise fashion if the face is 'facing' towards you (as opposed to away from you) as faces have a 'logical' side for lighting.

Parameters:

m map to change. lx X coordinate in space of light point ly Y coordinate in space of light point lz Z coordinate in space of light point lr light red value (0 - 255) lg light green value (0 - 255) lb light blue value (0 - 255) ar ambient color red value (0 - 255) ag ambient color green value (0 - 255) ab ambient color blue value (0 - 255)

EAPI void evas_map_util_3d_perspective (Evas_Map * m, Evas_Coord px, Evas_Coord py, Evas_Coord z0, Evas_Coord foc)

Apply a perspective transform to the map. This applies a given perspective (3D) to the map coordinates. X, Y and Z values are used. The px and py points specify the 'infinite distance' point in the 3D conversion (where all lines converge to like when artists draw 3D by hand). The z0 value specifis the z value at which there is a 1:1 mapping between spatial coorinates and screen coordinates. Any points on this z value will not have their X and Y values modified in the transform. Those further away (Z value higher) will shrink into the distance, and those less than this value will expand and become bigger. The foc value determines the 'focal length' of the camera. This is in reality the distance between the camera lens plane itself (at or closer than this rendering results are undefined) and the 'z0' z value. This allows for some 'depth' control and foc must be greater than 0.

Parameters:

m map to change. px The pespective distance X coordinate py The pespective distance Y coordinate z0 The '0' z plane value foc The focal distance

EAPI void evas_map_util_3d_rotate (Evas_Map * m, double dx, double dy, double dz, Evas_Coord cx, Evas_Coord cy, Evas_Coord cz)

Rotate the map around 3 axes in 3D. This will rotate not just around the 'Z' axis as in evas_map_util_rotate() (which is a convenience call for those only wanting 2D). This will rotate around the X, Y and Z axes. The Z axis points 'into' the screen with low values at the screen and higher values further away. The X axis runs from left to right on the screen and the Y axis from top to bottom. Like with evas_map_util_rotate(0 you provide a center point to rotate around (in 3D).

Parameters:

m map to change. dx amount of degrees from 0.0 to 360.0 to rotate arount X axis. dy amount of degrees from 0.0 to 360.0 to rotate arount Y axis. dz amount of degrees from 0.0 to 360.0 to rotate arount Z axis. cx rotation's center horizontal positon. cy rotation's center vertical positon. cz rotation's center vertical positon.

EAPI Eina_Bool evas_map_util_clockwise_get (Evas_Map * m)

Get the clockwise state of a map. This determines if the output points (X and Y. Z is not used) are clockwise or anti-clockwise. This can be used for 'back-face culling'. This is where you hide objects that 'face away' from you. In this case objects that are not clockwise.

Parameters:

m map to query.

Returns:

1 if clockwise, 0 otherwise

EAPI void evas_map_util_points_color_set (Evas_Map * m, int r, int g, int b, int a)

Set color of all points to given color. This call is useful to reuse maps after they had 3d lightning or any other colorization applied before.

Parameters:

m map to change the color of. r red (0 - 255) g green (0 - 255) b blue (0 - 255) a alpha (0 - 255)

See also:

evas_map_point_color_set()

EAPI void evas_map_util_points_populate_from_geometry (Evas_Map * m, Evas_Coord x, Evas_Coord y, Evas_Coord w, Evas_Coord h, Evas_Coord z)

Populate source and destination map points to match given geometry. Similar to evas_map_util_points_populate_from_object_full(), this call takes raw values instead of querying object's unmapped geometry. The given width will be used to calculate destination points (evas_map_point_coord_set()) and set the image uv (evas_map_point_image_uv_set()).

Parameters:

m map to change all 4 points (must be of size 4). x Point X Coordinate y Point Y Coordinate w width to use to calculate second and third points. h height to use to calculate third and fourth points. z Point Z Coordinate hint (pre-perspective transform). This value will be used for all four points.

See also:

evas_map_point_coord_set()
evas_map_point_image_uv_set()

EAPI void evas_map_util_points_populate_from_object (Evas_Map * m, const Evas_Object * obj)

Populate source and destination map points to match exactly object. Usually one initialize map of an object to match it's original position and size, then transform these with evas_map_util_* functions, such as evas_map_util_rotate() or evas_map_util_3d_rotate(). The original set is done by this function, avoiding code duplication all around.

Z Point coordinate is assumed as 0 (zero).

Parameters:

m map to change all 4 points (must be of size 4). obj object to use unmapped geometry to populate map coordinates.

EAPI void evas_map_util_points_populate_from_object_full (Evas_Map * m, const Evas_Object * obj, Evas_Coord z)

Parameters:

m map to change all 4 points (must be of size 4). obj object to use unmapped geometry to populate map coordinates. z Point Z Coordinate hint (pre-perspective transform). This value will be used for all four points.

EAPI void evas_map_util_rotate (Evas_Map * m, double degrees, Evas_Coord cx, Evas_Coord cy)

Change the map to apply the given rotation. This rotates the indicated map's coordinates around the center coordinate given by cx and cy as the rotation center. The points will have their X and Y coordinates rotated clockwise by degrees degress (360.0 is a full rotation). Negative values for degrees will rotate counter-clockwise by that amount. All coordinates are canvas global coordinates.

Parameters:

m map to change. degrees amount of degrees from 0.0 to 360.0 to rotate. cx rotation's center horizontal positon. cy rotation's center vertical positon.

evas_map_point_coord_set()
evas_map_util_zoom()

EAPI void evas_map_util_zoom (Evas_Map * m, double zoomx, double zoomy, Evas_Coord cx, Evas_Coord cy)

Change the map to apply the given zooming. Like evas_map_util_rotate(), this zooms the points of the map from a center point. That center is defined by cx and cy. The zoomx and zoomy parameters specific how much to zoom in the X and Y direction respectively. A value of 1.0 means 'don't zoom'. 2.0 means 'dobule the size'. 0.5 is 'half the size' etc. All coordinates are canvas global coordinates.

Parameters:

m map to change. zoomx horizontal zoom to use. zoomy vertical zoom to use. cx zooming center horizontal positon. cy zooming center vertical positon.

EAPI Eina_Bool evas_object_map_enable_get (const Evas_Object * obj)

Get the map enabled state. This returns the currently enabled state of the map on the object indicated. The default map enable state is off. You can enable and disable it with evas_object_map_enable_set().

Parameters:

obj object to get the map enabled state from

Returns:

the map enabled state

EAPI void evas_object_map_enable_set (Evas_Object * obj, Eina_Bool enabled)

Enable or disable the map that is set. This enables the map that is set or disables it. On enable, the object geometry will be saved, and the new geometry will change (position and size) to reflect the map geometry set. If none is set yet, this may be an undefined geometry, unless you have already set the map with evas_object_map_set(). It is suggested you first set a map with evas_object_map_set() with valid useful coordinates then enable and disable the map with evas_object_map_enable_set() as needed.

Parameters:

obj object to enable the map on enabled enabled state

EAPI const Evas_Map* evas_object_map_get (const Evas_Object * obj)

Get current object transformation map. This returns the current internal map set on the indicated object. It is intended for read-only acces and is only valid as long as the object is not deleted or the map on the object is not changed. If you wish to modify the map and set it back do the following:

  const Evas_Map *m = evas_object_map_get(obj);
  Evas_Map *m2 = evas_map_dup(m);
  evas_map_util_rotate(m2, 30.0, 0, 0);
  evas_object_map_set(obj);
  evas_map_free(m2);

Parameters:

obj object to query transformation map.

Returns:

map reference to map in use. This is an internal data structure, so do not modify it.

See also:

evas_object_map_set()

EAPI void evas_object_map_set (Evas_Object * obj, const Evas_Map * map)

Set current object transformation map. This sets the map on a given object. It is copied from the map pointer, so there is no need to keep the map object if you don't need it anymore.

A map is a set of 4 points which have canvas x, y coordinates per point, with an optional z point value as a hint for perspective correction, if it is available. As well each point has u and v coordinates. These are like 'texture coordinates' in OpenGL in that they define a point in the source image that is mapped to that map vertex/point. The u corresponds to the x coordinate of this mapped point and v, the y coordinate. Note that these coordinates describe a bounding region to sample. If you have a 200x100 source image and wannt to display it at 200x100 with proper pixel precision, then do:

  Evas_Map *m = evas_map_new(4);
  evas_map_point_coord_set(m, 0,   0,   0, 0);
  evas_map_point_coord_set(m, 1, 200,   0, 0);
  evas_map_point_coord_set(m, 2, 200, 100, 0);
  evas_map_point_coord_set(m, 3,   0, 100, 0);
  evas_map_point_image_uv_set(m, 0,   0,   0);
  evas_map_point_image_uv_set(m, 1, 200,   0);
  evas_map_point_image_uv_set(m, 2, 200, 100);
  evas_map_point_image_uv_set(m, 3,   0, 100);
  evas_object_map_set(obj, m);
  evas_map_free(m);

Note that the map points a uv coordinates match the image geometry. If the map parameter is NULL, the sotred map will be freed and geometry prior to enabling/setting a map will be restored.

Parameters:

obj object to change transformation map map new map to use
