explicit

これはオーバーロードされたメンバ関数です。利便性のために用意されています。元の関数との違いは引き数のみです。

引数

arr	Input array (host or device memory, it can be Mat , cuda::GpuMat or ogl::Buffer ).
autoRelease	Auto release mode (if true, release will be called in object's destructor).

関数詳解

copyFrom()

void cv::ogl::Texture2D::copyFrom	(	InputArray	arr,
		bool	autoRelease = false
	)

Copies from host/device memory to OpenGL texture.

引数

arr	Input array (host or device memory, it can be Mat , cuda::GpuMat or ogl::Buffer ).
autoRelease	Auto release mode (if true, release will be called in object's destructor).

copyTo()

void cv::ogl::Texture2D::copyTo	(	OutputArray	arr,
		int	ddepth = CV_32F,
		bool	autoRelease = false
	)		const

Copies from OpenGL texture to host/device memory or another OpenGL texture object.

引数

arr	Destination array (host or device memory, can be Mat , cuda::GpuMat , ogl::Buffer or ogl::Texture2D ).
ddepth	Destination depth.
autoRelease	Auto release mode for destination buffer (if arr is OpenGL buffer or texture).

create() [1/2]

void cv::ogl::Texture2D::create	(	int	arows,
		int	acols,
		Format	aformat,
		bool	autoRelease = false
	)

Allocates memory for ogl::Texture2D object.

引数

arows	Number of rows.
acols	Number of columns.
aformat	Image format. See cv::ogl::Texture2D::Format .
autoRelease	Auto release mode (if true, release will be called in object's destructor).

create() [2/2]

void cv::ogl::Texture2D::create	(	Size	asize,
		Format	aformat,
		bool	autoRelease = false
	)

これはオーバーロードされたメンバ関数です。利便性のために用意されています。元の関数との違いは引き数のみです。

引数

asize	2D array size.
aformat	Image format. See cv::ogl::Texture2D::Format .
autoRelease	Auto release mode (if true, release will be called in object's destructor).

release()

void cv::ogl::Texture2D::release

(

)

Decrements the reference counter and destroys the texture object if needed.

The function will call setAutoRelease(true) .

setAutoRelease()

void cv::ogl::Texture2D::setAutoRelease

(

bool

flag

)

Sets auto release mode.

引数

flag	Auto release mode (if true, release will be called in object's destructor).

The lifetime of the OpenGL object is tied to the lifetime of the context. If OpenGL context was bound to a window it could be released at any time (user can close a window). If object's destructor is called after destruction of the context it will cause an error. Thus ogl::Texture2D doesn't destroy OpenGL object in destructor by default (all OpenGL resources will be released with OpenGL context). This function can force ogl::Texture2D destructor to destroy OpenGL object.
