Member Function Documentation

acquire_image_buffer()

ImBuf * blender::draw::image_engine::SpaceNodeAccessor::acquire_image_buffer ( Image * image, void ** lock )

inlineoverridevirtual

Acquire the image buffer of the image.

Parameters

image	Image to get the buffer from. Image is the same as returned from the get_image member.
lock	pointer to a lock object.

Returns

Image buffer of the given image.

Implements blender::draw::image_engine::AbstractSpaceAccessor.

get_image()

Image * blender::draw::image_engine::SpaceNodeAccessor::get_image ( Main * bmain )

inlineoverridevirtual

Return the active image of the space.

The returned image will be drawn in the space.

The return value is optional.

Implements blender::draw::image_engine::AbstractSpaceAccessor.

References BKE_image_ensure_viewer(), and IMA_TYPE_COMPOSITE.

get_image_user()

ImageUser * blender::draw::image_engine::SpaceNodeAccessor::get_image_user ( )

inlineoverridevirtual

Return the ImageUser of the space.

The return value is optional.

Implements blender::draw::image_engine::AbstractSpaceAccessor.

Definition at line 26 of file image_space_node.hh.

get_shader_parameters()

void blender::draw::image_engine::SpaceNodeAccessor::get_shader_parameters ( ShaderParameters & r_shader_parameters, ImBuf * image_buffer )

inlineoverridevirtual

Update the r_shader_parameters with space specific settings.

Only update the ShaderParameters.flags and ShaderParameters.shuffle. Other parameters are updated inside the image engine.

Implements blender::draw::image_engine::AbstractSpaceAccessor.

init_ss_to_texture_matrix()

void blender::draw::image_engine::SpaceNodeAccessor::init_ss_to_texture_matrix ( const ARegion * region, const float image_offset[2], const float image_resolution[2], float r_uv_to_texture[4][4] ) const

inlineoverridevirtual

The backdrop of the node editor isn't drawn in screen space UV space. But is locked with the screen.

release_buffer()

void blender::draw::image_engine::SpaceNodeAccessor::release_buffer ( Image * image, ImBuf * image_buffer, void * lock )

inlineoverridevirtual

Release a previous locked image from acquire_image_buffer.

Implements blender::draw::image_engine::AbstractSpaceAccessor.

use_tile_drawing()

bool blender::draw::image_engine::SpaceNodeAccessor::use_tile_drawing ( ) const

inlineoverridevirtual

Is (wrap) repeat option enabled in the space.

Implements blender::draw::image_engine::AbstractSpaceAccessor.
