Class Image

Namespace

easyar

Assembly

EasyAR.Sense.dll

Image stores image data, used to represent images in memory. Image provides access to raw data in the form of a byte array, and also provides an interface to access information such as width/height. In all versions of EasyAR Sense, you can access image data.

In iOS, you can access it like this ::

#import <easyar/buffer.oc.h> #import <easyar/image.oc.h>

easyar_OutputFrame * outputFrame = [outputFrameBuffer peek]; if (outputFrame != nil) { easyar_Image * i = [[outputFrame inputFrame] image]; easyar_Buffer * b = [i buffer]; char * bytes = calloc([b size], 1); memcpy(bytes, [b data], [b size]); // use bytes here free(bytes); }

In Android, ::

import cn.easyar.*;

OutputFrame outputFrame = outputFrameBuffer.peek(); if (outputFrame != null) { InputFrame inputFrame = outputFrame.inputFrame(); Image i = inputFrame.image(); Buffer b = i.buffer(); byte[] bytes = new byte[b.size()]; b.copyToByteArray(0, bytes, 0, bytes.length); // use bytes here b.dispose(); i.dispose(); inputFrame.dispose(); outputFrame.dispose(); }

public Image(Buffer buffer, PixelFormat format, int width, int height)

Parameters

buffer

format

width

height

Methods

Clone()

public Image Clone()

Returns

CloneObject()

protected override object CloneObject()

Returns

buffer()

Returns the data buffer in the image. You can use the `Buffer`_ API to access the internal data. Do not modify the content of the obtained data `Buffer`_, as it may be used in other threads.

public virtual Buffer buffer()

Returns

create(Buffer, PixelFormat, int, int, int, int)

public static Image create(Buffer buffer, PixelFormat format, int width, int height, int pixelWidth, int pixelHeight)

Parameters

buffer

format

width

height

pixelWidth

pixelHeight

Returns

format()

Returns the image format.

public virtual PixelFormat format()

Returns

height()

Returns the image height. There will be padding of pixelHeight - height pixels below the image data.

public virtual int height()

Returns

pixelHeight()

Returns the pixel height used when encoding the image.

public virtual int pixelHeight()

Returns

pixelWidth()

Returns the pixel width used when encoding the image.

public virtual int pixelWidth()

Returns

width()

Returns the image width. There will be padding of pixelWidth - width pixels to the right of the image data.

public virtual int width()

Returns
