Efl.Gfx.Buffer (interface)

Common APIs for all objects representing images and 2D pixel buffers.

alpha (get, set)

Indicates whether the alpha channel should be used.

Eina_Bool efl_gfx_buffer_alpha_get(const Eo *obj);
void efl_gfx_buffer_alpha_set(Eo *obj, Eina_Bool alpha);

buffer_borders (get)

void efl_gfx_buffer_borders_get(const Eo *obj, unsigned int *l, unsigned int *r, unsigned int *t, unsigned int *b);

buffer_copy_set

Set the pixels for this buffer by copying them, or allocate a new memory region.

Eina_Bool efl_gfx_buffer_copy_set(Eo *obj, const Eina_Slice *slice, Eina_Size2D size, int stride, Efl_Gfx_Colorspace cspace, int plane);

buffer_managed_get

Get a direct pointer to the internal pixel data, if available.

Eina_Slice efl_gfx_buffer_managed_get(Eo *obj, int plane);

buffer_managed_set

Set the pixels for this buffer, managed externally by the client.

Eina_Bool efl_gfx_buffer_managed_set(Eo *obj, const Eina_Slice *slice, Eina_Size2D size, int stride, Efl_Gfx_Colorspace cspace, int plane);

buffer_map

Map a region of this buffer for read or write access by the CPU.

Eina_Rw_Slice efl_gfx_buffer_map(Eo *obj, Efl_Gfx_Buffer_Access_Mode mode, const Eina_Rect *region, Efl_Gfx_Colorspace cspace, int plane, int *stride);

buffer_size (get, set)

Rectangular size of the pixel buffer as allocated in memory.

Eina_Size2D efl_gfx_buffer_size_get(const Eo *obj);
void efl_gfx_buffer_size_set(Eo *obj, Eina_Size2D sz);

buffer_unmap

Unmap a region of this buffer, and update the internal data if needed.

Eina_Bool efl_gfx_buffer_unmap(Eo *obj, Eina_Rw_Slice slice);

buffer_update_add

Mark a sub-region of the given image object to be redrawn.

void efl_gfx_buffer_update_add(Eo *obj, const Eina_Rect *region);

colorspace (get)

Returns the current encoding of this buffer's pixels.

Efl_Gfx_Colorspace efl_gfx_buffer_colorspace_get(const Eo *obj);

stride (get)

int efl_gfx_buffer_stride_get(const Eo *obj);
