for a project, I am trying to provide a user interface where a user can position sensors on a foot and then save the sensors position in the image to display them later :
In doing, so I create 5 images, one per sensor and the image of the foot mapping but I have no idea how to put the sensors icon in the image and then save their position inside the image. I have the following code :
<p>Put on the foot mapping the sensors position</p>
<img
alt="foot_mapping"
src={require("assets/img/theme/circle-1.png")}
class="inner-image"
width="40em"
height="40em"
/>
<img
alt="foot_mapping"
src={require("assets/img/theme/circle-2.png")}
class="inner-image"
width="40em"
height="40em"
/>
<img
alt="foot_mapping"
src={require("assets/img/theme/circle-3.png")}
class="inner-image"
width="40em"
height="40em"
/>
<img
alt="foot_mapping"
src={require("assets/img/theme/circle-4.png")}
class="inner-image"
width="40em"
height="40em"
/>
<img
alt="foot_mapping"
src={require("assets/img/theme/circle-5.png")}
class="inner-image"
width="40em"
height="40em"
/>
<img
alt="foot_mapping"
src={require("assets/img/theme/foot.png")}
width="80%"
height="80%"
/>
I tried the inner image with no luck yet and I didn't find other ressources regarding this problem.
Thanks in advance :)
How can I display a PDF in a Laravel View like I can display a normal image?
The code I am using to implement an image is:
<div class="u-img">
<img
src="image/{{ Auth::user()->photo_jpeg }}"
alt="profile"
/>
</div>
What options/HTML-tags can I use to display a PDF?
you could use an object
<object data="/path/to/pdf.pdf" type="application/pdf">
</object>
you could use an iframe
<iframe src="http://example.com/pdf-sample.pdf" id="pdf_display_frame" width="100%" height="500px"></iframe>
I want something to happen in p5js when the mouse is over a map of a country (which is not a standard shape). How can I do that? I mean how can I track a mouse on a non-standard shape like the map of a country?
(I've loaded this shape as an image and the spots out of the borders are still part of the image but are transparent. )
Thanks
There are a few ways to do this:
You could get the geometry in your code, and use that to check whether the cursor is inside the shape. Then google something like "check if point is inside polygon" for a ton of resources. You can do this even if you still want to use an image, or you could draw the shape using the createShape() method instead.
Or you could check the color under the mouse. If it's not the background color, then you're inside the shape. This will only work if you only have one country, or if every country is a different color.
If I were you, I would lean towards the first option. Get something simple working first: create a hard-coded shape, and then create a sketch that prints a message to the console when the mouse clicks inside that shape. Then get the geometry for the country and use that instead of the hard-coded shape.
Then if you get stuck, you can post a MCVE along with a more specific technical question. Good luck.
Rather than going through effort to track the mouse and perform your own colission-detection, why not go old-school and use <map> and <area>?
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/area
The HTML <area> element defines a hot-spot region on an image, and optionally associates it with a hypertext link. This element is used only within a <map> element.
The HTML <map> element is used with elements to define an image map (a clickable link area).
<area> is represented in the DOM by HTMLAreaElement which implements the HTMLElement interface so you can listen to mouseover events coming from the <area> elements:
Example HTML (from the MDN article):
<map name="infographic" id="myInfographic">
<area shape="rect" coords="184,6,253,27"
href="https://mozilla.org"
target="_blank" alt="Mozilla" />
<area shape="circle" coords="130,136,60"
href="https://developer.mozilla.org/"
target="_blank" alt="MDN" />
<area shape="poly" coords="130,6,253,96,223,106,130,39"
href="https://developer.mozilla.org/docs/Web/Guide/Graphics"
target="_blank" alt="Graphics" />
<area shape="poly" coords="253,96,207,241,189,217,223,103"
href="https://developer.mozilla.org/docs/Web/HTML"
target="_blank" alt="HTML" />
<area shape="poly" coords="207,241,54,241,72,217,189,217"
href="https://developer.mozilla.org/docs/Web/JavaScript"
target="_blank" alt="JavaScript" />
<area shape="poly" coords="54,241,6,97,36,107,72,217"
href="https://developer.mozilla.org/docs/Web/API"
target="_blank" alt="Web APIs" />
<area shape="poly" coords="6,97,130,6,130,39,36,107"
href="https://developer.mozilla.org/docs/Web/CSS"
target="_blank" alt="CSS" />
</map>
<img usemap="#infographic" src="/media/examples/mdn-info.png" alt="MDN infographic" />
Script:
var areas = document.querySelectorAll( '#myInfographic area' );
for( var i = 0; i < areas.length; i++ ) {
areas[i].addEventListener( 'mouseover', function( e ) {
console.log( 'over some area' );
} );
}
I have an image gallery on my site that uses thumbnails that enlarge above the thumbnail line when clicked on. I'm having an issue with the auto-refresh; every time I click one of the thumbnails, the page refreshes, which restores it to the "master image".
I'm not (and sort of refuse, on the grounds that I believe all this can be done with simple CSS and HTML) using anything fancy to write this code, despite my knowledge of HTML being amateur at best.
Here's a sample of the code. Let me know if you need to see a different piece of it.
<div id="rightcol">
<img name="ImageOnly. src='#' /><img src="#" />
</div>
<div id="leftcol"> <div>
<a href="" onclick="ImageOnly.src='#'"><img src="#" />
</div>
Edit: Somehow I seem to have fixed this issue by changing
<a href="" onclick="ImageOnly.src='#'">
to
<a href="#" onclick="ImageOnly.src='#'">
Not really sure why this worked but would love an explanation...?
Why not just use some simple ajax/javascript .innerHTML? instead of trying to stop the auto refresh that occurs when you click on a hyperlink that has #. That way you could update the rightcol synchroniously.
HTML
<div id="rightcol">
<img name="ImageOnly.src" src='#' />
</div>
<div id="leftcol">
<img src="#" />
</div>
AJAX Script
function ajaxMove(src)
{
var image = '<img src="'+src+'" alt="my transferred image" />';
document.getElementById('rightcol').innerHTML = image;
}
How is it used?
Request the object from the onclick event.
Build an image tag based off the information in the object.
Transfer the new image tag to the element with the id 'rightcol'
Other options
You could also remove the href="#" from the <a> tag and work directly from the onclick event and then apply style="cursor:pointer;". Then it will work like a regular hyperlink but without the refresh.
<a onclick="javascript:ajaxMove('ImageOnly.src')" style="cursor:pointer;" >Click Me</a>
I need to display some graphical chart data on a website. In these charts are several images that when clicked on should display a larger version of the image. The charts themselves are currently saved as a single image file.
My initial thoughts are to use an imagemap to specify where the images are in the overall chart image and then use jQuery to highlight around the edge of the images. Then using something like lightbox or fancybox display the larger version clicked on image.
What I would appreciate is some insight as to whether this is the best way to achieve the desired result or if there is a better technique?
Thanks
Why not just use a tooltip?
Here is an example using qTip2, with some borrowed code ;)
HTML
<img src="planets.gif" width="145" height="126" alt="Planets" usemap="#planetmap" />
<map name="planetmap">
<area shape="rect" coords="0,0,82,126" alt="Sun" href="#" title="<img src='sun.gif'>" />
<area shape="circle" coords="90,58,3" alt="Mercury" href="#" title="<img src='merglobe.gif'>" />
<area shape="circle" coords="124,58,8" alt="Venus" href="#" title="<img src='venglobe.gif'>" />
</map>
Script
$('area').qtip({
position: {
my: 'left center',
at: 'right center',
target: $('img')
}
});
