EncodePng

tensorflow C++ API

tensorflow::ops::EncodePng

PNG-encode an image.

Summary

imageis a 3-D uint8 or uint16Tensorof shape[height, width, channels]wherechannelsis:

• 1: for grayscale.
• 2: for grayscale + alpha.
• 3: for RGB.
• 4: for RGBA.

The ZLIB compression level,compression, can be -1 for the PNG-encoder default or a value from 0 to 9. 9 is the highest compression level, generating the smallest output, but is slower.

Arguments:

• scope: A Scope object
• image: 3-D with shape [height, width, channels].

Returns:

• Output: 0-D. JPEG-encoded image.

Optional attributes (seeAttrs):

• compression: Compression level.

Constructor

• EncodePng(const ::tensorflow::Scope & scope, ::tensorflow::Input image, const EncodePng::Attrs & attrs) .

Public attributes

• tensorflow::Output contents.

Argument:

• Scope scope : A Scope object (A scope is generated automatically each page. A scope is not connected.)
• image: connect Input node.
• EncodePng::Attrs attrs : input attrs value. ex) compression_ = -1;

Return:

• Output contents : Output object of EncodeJpeg class object.

Result:

• std::vector(Tensor) product_result : Returned object of executed result by calling session.
