3d object converter stream read error
The use of events and event handlers allows separate code blocks the ability Through event handler content attributes and the firing of events.
This specification defines an asynchronous API based on an event model to read and access a File or Blob’s data.Ī FileReader object provides asynchronous read methods to access that file’s data With an optional synchronous API used within threaded web applications.Īn asynchronous API for reading files prevents blocking and UI "freezing" on a user agent’s main thread. File or Blob reads should happen asynchronously on the main thread,
("Binary Large Object" - a name originally introduced to web APIs in Google Gears) The File interface represents file data typically obtained from the underlying file system, The interfaces and API defined in this specification can be used with other interfaces and APIs exposed to the web platform. Which can be asynchronously processed on the main thread of conforming user agents. This specification defines the basic representations for files,Īdditionally, this specification also defines an interface that represents "raw data" Including files that a user may wish to upload to a remote server or manipulate inside a rich web application. Web applications should have the ability to manipulate as wide as possible a range of user input, 8.4.1 Examples of blob URL Creation and Revocation.8 A URL for Blob and MediaSource reference.7.1 Throwing an Exception or Returning an Error.6.5.1.5 The readAsBinaryString() method.6.2.3.4 The readAsBinaryString() method.This document is governed by the 15 September 2020 W3C Process Document.

These kinds of behaviors are defined in the appropriate affiliated specifications. with an overloaded send() method for File or Blob arguments), postMessage(), DataTransfer (part of the drag and drop API defined in )Īdditionally, it should be possible to programmatically obtain a list of files from the input element This API is designed to be used in conjunction with other APIs and elements on the web platform, notably: XMLHttpRequest (e.g. § 10 Requirements and Use Cases covers the motivation behind this specification. Ī URL scheme for use with binary data such as files, so that they can be referenced within web applications.Īdditionally, this specification defines objects to be used within threaded web applications for the synchronous reading of files.Ī FileReader interface, which provides methods to read a File or a Blob, and an event model to obtain the results of these reads.Ī File interface, which includes readonly informational attributes about a file such as its name and the date of the last modification (on disk) of the file.Ī Blob interface, which represents immutable raw binary data, and allows access to ranges of bytes within the Blob object as a separate Blob.when the input element is in the File Upload state. The user interface for selection can be invoked via, i.e. This includes:Ī FileList interface, which represents an array of individually selected files from the underlying system. This specification provides an API for representing file objects in web applications,Īs well as programmatically selecting them and accessing their data.
