Scaling

enum class open3d::visualization::gui::UIImage::Scaling

strong

Enumerator
NONE
ANY	No scaling, fixed size.
ASPECT	Scales to any size and aspect ratio. Scales to any size, but fixed aspect ratio (default)

Constructor & Destructor Documentation

UIImage() [1/4]

open3d::visualization::gui::UIImage::UIImage ( const char * image_path )

explicit

UIImage() [2/4]

open3d::visualization::gui::UIImage::UIImage ( std::shared_ptr< geometry::Image > image )

explicit

UIImage() [3/4]

open3d::visualization::gui::UIImage::UIImage ( std::shared_ptr< t::geometry::Image > image )

explicit

UIImage() [4/4]

open3d::visualization::gui::UIImage::UIImage ( visualization::rendering::TextureHandle texture_id, float u0 = 0.0f, float v0 = 0.0f, float u1 = 1.0f, float v1 = 1.0f )

explicit

Uses an existing texture, using texture coordinates (u0, v0) to (u1, v1). Does not deallocate texture on destruction. This is useful for using an icon atlas to reduce draw calls.

UpdateImage() [1/2]

void open3d::visualization::gui::UIImage::UpdateImage

(

std::shared_ptr< geometry::Image >

image

)

Updates the contents of the texture. If the image is a different size from the original, a new texture will be created.

UpdateImage() [2/2]

void open3d::visualization::gui::UIImage::UpdateImage

(

std::shared_ptr< t::geometry::Image >

image

)

Updates the contents of the texture. If the image is a different size from the original, a new texture will be created.
