DecodePng

tensorflow C++ API

tensorflow::ops::DecodePng

Decode a PNG-encoded image to a uint8 or uint16 tensor.

Summary

The attrchannelsindicates the desired number of color channels for the decoded image.

Accepted values are:

• 0: Use the number of channels in the PNG-encoded image.
• 1: output a grayscale image.
• 3: output an RGB image.
• 4: output an RGBA image.

If needed, the PNG-encoded image is transformed to match the requested number of color channels.

This op also supports decoding JPEGs and non-animated GIFs since the interface is the same, though it is cleaner to usetf.image.decode_image.

Arguments:

• scope: A Scope object
• contents: 0-D. The PNG-encoded image.

Optional attributes (seeAttrs):

• channels: Number of color channels for the decoded image.

Returns:

• Output: 3-D with shape[height, width, channels].

Constructor

• DecodePng(const ::tensorflow::Scope & scope, ::tensorflow::Input contents, const DecodePng::Attrs & attrs).

Public attributes

• tensorflow::Output output.

Argument:

• Scope scope : A Scope object (A scope is generated automatically each page. A scope is not connected.)
• contents: connect Input node.
• DecodePng::Attrs attrs : input attrs value. ex) channels_ = 0; dtype_ = DT_UINT8;

Return:

• Output image : Output object of DecodePng class object.

Result:

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