<h2>File Not Found</h2>

<p>We recommend that you update the default path in <span class="text_button" title="Show Project Settings" onclick="settings_panel_toggle()">project settings</span> to the folder which contains this image.</p>
<p>A temporary fix is to use <span class="text_button" title="Load or Add Images" onclick="sel_local_images()">browser's file selector</span> to manually locate and add this file. We do not recommend this approach because it requires you to repeat this process every time your load this project in the VIA application.</p>

<ol>
<li><strong>Load Images</strong>: The first step is to load all the images that you wish to annotate. There are multiple ways to add images to a VIA project. Choose the method that suits your use case.
<ul>
<li>Method 1: Selecting local files using browser's file selector
<ol>
<li>Click <span class="text_button" title="Load or Add Images" onclick="sel_local_images()"><code>Project → Add local files</code></span></li>
<li>Select desired images and click <code>Open</code></li>
</ol>
</li>
<li>Method 2: Adding files from URL or absolute path
<ol>
<li>Click <span class="text_button" title="Add images from a web URL (e.g. http://www.robots.ox.ac.uk/~vgg/software/via/images/swan.jpg)" onclick="project_file_add_url_with_input()"><code>Project → Add files from URL</code></span></li>
<li>Enter URL and click <code>OK</code></li>
</ol>
</li>
<li>Method 3: Adding files from list of url or absolute path stored in text file
<ol>
<li>Create a text file containing URL and absolute path (one per line)</li>
<li>Click <span class="text_button" title="Add images from a list of web url or absolute path stored in a text file (one url or path per line)" onclick="sel_local_data_file('files_url')"><code>Project → Add url or path from text file</code></span></li>
<li>Select the text file and click <code>Open</code></li>
</ol>
</li>
</ul>
</li>
<li><strong>Draw Regions</strong>: Select a region shape (<span class="text_button" onclick="select_region_shape('rect')">rectangle</span>, <span class="text_button" onclick="select_region_shape('circle')">circle</span>, <span class="text_button" onclick="select_region_shape('ellipse')">ellipse</span>, <span class="text_button" onclick="select_region_shape('polygon')">polygon</span>, <span class="text_button" onclick="select_region_shape('point')">point</span>, <span class="text_button" onclick="select_region_shape('polyline')">polyline</span>) from the left sidebar and draw regions as follows:
<ul>
<li>Rectangle, Circle and Ellipse
<ul>
<li>Press left mouse button, drag mouse cursor and release mouse button.</li>
<li>To define a point inside an existing region, click inside the region to select it (if not already selected), now press left mouse button, drag and release to draw region inside existing region.</li>
<li>To select, click inside the region. If the click point contains multiple regions, then clicking multiple times at that location shuffles selection through those regions.</li>
</ul>
</li>
</ul>
<ul>
<li>Point
<ul>
<li>Click to define points.</li>
<li>To draw a region inside existing region, click inside the region to select it (if not already selected), now click again to define the point.</li>
<li>To select, click on (or near) the existing point.</li>
</ul>
</li>
</ul>
<ul>
<li>Polygon and Polyline
<ul>
<li>Click to define vertices.</li>
<li>Press <strong>[Enter]</strong> to finish drawing the region or press [Esc] to cancel.</li>
<li>If the first vertex needs to be defined inside an existing region, click inside the region to select it (if not already selected), now click again to define the vertex.</li>
<li>To select, click inside the region. If the click point contains multiple regions, then clicking multiple times at that location shuffles selection through those regions.</li>
</ul>
</li>
</ul>
</li>
<li><strong>Create Annotations</strong>: For a more detailed description of this step, see <a href="http://www.robots.ox.ac.uk/~vgg/software/via/docs/creating_annotations.html">Creating Annotations : VIA User Guide</a>. Click the <span class="text_button" onclick="annotation_editor_toggle_all_regions_editor()"><code>View → Toggle attributes editor</code></span> to show attributes editor panel in left sidebar and add the desired file or region attributes (e.g. name). Now click <span class="text_button" onclick="annotation_editor_toggle_all_regions_editor()"><code>View → Toggle annotations editor</code></span> to show the annotation editor panel in the bottom side. Update the annotations for each region.</li>
<li><strong>Export Annotations</strong>: To export the annotations in json or csv format, click <span class="text_button" onclick="download_all_region_data('csv')"><code>Annotation → Export annotations</code></span> in top menubar.</li>
<li><strong>Save Project</strong>: To save the project, click <span class="text_button" onclick="project_save_with_confirm()"><code>Project → Save</code></span> in top menubar.</li>

<p>VGG Image Annotator (VIA) is an image annotation tool that can be used to define regions in an image and create textual descriptions of those regions. VIA is an <a href="https://gitlab.com/vgg/via/">open source project</a> developed at the <a href="http://www.robots.ox.ac.uk/~vgg/">Visual Geometry Group</a> and released under the BSD-2 clause <a href="https://gitlab.com/vgg/via/blob/master/LICENSE">license</a>.</p>
<p>Here is a list of some salient features of VIA:
<ul>
<li>based solely on HTML, CSS and Javascript (no external javascript libraries)</li>
<li>can be used off-line (full application in a single html file of size < 400KB)</li>
<li>requires nothing more than a modern web browser (tested on Firefox, Chrome and Safari)</li>
<li>supported region shapes: rectangle, circle, ellipse, polygon, point and polyline</li>
<li>import/export of region data in csv and json file format</li>
</ul>
