EasyAR.Sense.dll

ImageTarget represente un target pour une planar image, which can be tracked by `ImageTracker`_. Values in ImageTarget must first be filled by create... methods before they can be read. Then, after it is successfully loaded into `ImageTracker`_ through `ImageTracker.loadTarget`_, it can be detected and tracked by `ImageTracker`_.

Clone()

aspectRatio()

Aspect ratio of the image.

public virtual float aspectRatio()

createFromImageFile(string, StorageType, string, string, string, float)

Cree from an image. If not needed, name, uid, and meta can be empty strings, and scale can use the default value 1. jpeg or png files are supported.

createFromTargetData(Buffer)

Cree from an etd data buffer.

createFromTargetFile(string, StorageType)

images()

Obtient the list of images stored in the target. This method is usually used to get the recognition images of a target returned from the cloud.

public virtual List<Image> images()

meta()

Obtient the meta data set by setMetaData. Or, in a target returned by cloud recognition, gets the meta data set by the server.

public override string meta()

name()

Obtient the target name. The name is used to distinguish targets in a json file.

public override string name()

runtimeID()

Obtient the target id. target id is integer data created at runtime and is valid (non-zero) only after successful configuration. This id is non-zero and globally incremental.

public override int runtimeID()

save(string)

Saves as an etd file.

public virtual bool save(string path)

Paramètres

path

scale()

Scale ratio of the image. Its value is the ratio between the physical width of the image and 1 meter. The default value is 1.

public virtual float scale()

setMeta(string)

Definit meta data. This operation overrides the previous setting or data returned by the server.

public override void setMeta(string data)

Paramètres

data

setName(string)

Definit the target name. This operation overrides the previous setting or data returned by the server.

public override void setName(string name)

Paramètres

name

setScale(float)

Sets the scale ratio of the image. After it is set, it overrides the default value and the value set in the json file. Its value is the ratio between the physical width of the image and 1 meter. The default value is 1. This model scale also needs to be set separately in the rendering engine.

public virtual bool setScale(float scale)

Paramètres

scale

uid()

Obtient the target uid. The uid of ImageTarget is used in the cloud recognition algorithm. When cloud recognition is not integrated, you can set this uid in json configuration and use it in your own code as another way to distinguish targets.

public override string uid()
