◆ allocatePages()

std::vector< Page > tt::pipeline_image::device_shared::allocatePages ( size_t num_pages )

noexcept

Allocate pages from the atlas.

void tt::pipeline_image::device_shared::destroy ( gui_device_vulkan * vulkanDevice )

Deallocate vulkan resources. This is called in the destructor of gui_device_vulkan, therefor we can not use our std::weak_ptr<gui_device_vulkan> device.

void tt::pipeline_image::device_shared::freePages ( std::vector< Page > const & pages )

noexcept

Deallocate pages back to the atlas.

static point3 tt::pipeline_image::device_shared::getAtlasPositionFromPage ( Page page )

inlinestaticnoexcept

Get the coordinate in the atlas from a page index.

Parameters

page	number in the atlas

Returns: x, y pixel coordinate in an atlasTexture and z the atlasTextureIndex.

Image tt::pipeline_image::device_shared::makeImage	(	size_t	width,
		size_t	height )

noexcept

Allocate an image in the atlas.

Parameters

width	of the image.
height	of the image.
