I am evaluating a completely headless setup with kirby.
I would like to be able to upload an image in one big size and kirby should generate different sizes of responsive images. (I know this feature from WordPress where this is possible).
I see there is this: https://getkirby.com/docs/guide/templates/resize-images-on-the-fly
But this is all php kirby code, and I want just to consume the REST API. So now kirby syntax available.
I tried to preconfigure the sizes within site/config/config.php but when uploading a new image, it would not save it in different sizes…
I then thought, maybe it would just generate the specific size the first time the image is requested. I've seen this behaviour with multiple CDNs. But also I did not find any documentation about that.
So what would be the best way to upload an image, and then being able to load a resized version of that image via REST API?
Is there even a possibility?
thank you for every input on that.
Cheers
Well some time has passed and I learnt a bit more about kirby and how it works.
The image is generated on the fly, when executing kirby syntax like $file->resize(720, null, 60)->url() (read more: https://getkirby.com/docs/guide/templates/resize-images-on-the-fly)
So to get images in different sizes via REST API, one can write a custom route where you are responsible of executing these resize commands whenever somebody is consuming this endpoint. A simpler solution would be using the plugin better-rest (https://github.com/robinscholz/better-rest) which does part of it for you already (for example in the better-rest endpoint images are amongst other stuff returned as srcset).
I hope this helps somebody one day. Cheers

I'm trying to get version of a photo that FB uses as the background image for album layouts where one side is always exactly 206px and the other one at least the same, for example https://fbcdn-sphotos-b-a.akamaihd.net/hphotos-ak-xpa1/v/t1.0-9/p206x206/10401476_409218399235620_1454525834273554679_n.jpg?oh=eda59fce63113796b35c46cc4bec162a&oe=55760EFD&gda=1433681435_6b4729404e05493108c271a50c753d7f I've scoured both the graph and SO, but am having absolutely no luck here. I'm aware that you can get 3 versions of a photo using type=album/thumbnail/normal ie https://graph.facebook.com/409218399235620/picture?type=album (you'd think this one would work, but they probably never updated it to redirect to the new size?). I've tried all kinds of variants of this knowing that the graph documentation is pretty crap, to no avail.
I've also used the Explorer to for example pull up ?fields=images, but it's never one of the listed images there. I've tried using widths, replacing parts of the URL etc. etc. I am running the checks with a valid access_token.
I've pretty much resigned myself to just resizing myself, but given the time I've spent on this, I thought I'd at least put it out there in case someone else has had the same problem, and come up with a solution.
I am trying to upload an image to Twitter and make it appear automatically, meaning not needing to click "Show Photo". I am able to post a status and image using POST statuses/update_with_media. That is fairly easy to do, but it still does not appear "inline." The documentation shows an example of uploading an image with twurl but I am working on Windows. Does anyone have an example with jQuery or a REST client showing how to us the https://upload.twitter.com/1.1/media/upload.json service? I tried putting the parameters in the url and the body but each time I get Bad Request.
Even though I spend about 15 hours working on this, I found a "solution" 10 minutes after posting on SO. It seems that the size of the image plays a role. I just used statuses/update_with_media using a larger image and it appeared inline. A slightly smaller image does not appear inline. I would still like to know how to call the service though.
I want to run an A/B-test or an experiment for whole part of the site. For example on my /blog/ page, where one variation would have a newsletter form and other variation a free ebook download button.
The problem is that I have to use a full URL path for the experiments, for example /blog/2013/article/1?var=1 and /blog/2013/article/1?var=2 With this method I would need create a new experiment for each blog post. This is impossible.
Any tips on how to approach this?
It's possible, but the documentation is lacking.
When you choose your variation URLs, you need to use relative instead of http://. This let's you use query parameters to define the variations, instead of the full URL. In your example, you would define your original page as:
http: //www.example.com/blog/2013/article/1
and your variation URLs would be ?var=1, var=2, etc. using relative as the option in the dropdown (instead of http:// or https://).
Here's the not-so-clear documentation on using relative URLs for your variations:
https://support.google.com/analytics/answer/2664470?hl=en&ref_topic=1745208
One important thing to remember is that if you're doing it this way, you need to include the content experiment code on every "original" page.
There's also another way to have even more control over serving the variation pages and controlling the experiment using the Content Experiments JavScript API. This is a relatively new feature - you can see the developer documentation about this here:
https://developers.google.com/analytics/devguides/collection/gajs/experiments
I am not sure this is possible. You might look at a more robust yet simple to use tool like Visual Website Optimizer or Optimizely.
I'm building a website using GWT and would like to add Image Cropping capability so users can upload their profile image and then crop it as they need to. I'm looking for something similar to Jcrop but in GWT.
I found THIS and THIS code samples how to crop an image on the client side but there is no UI part where user can select part of their image that needs to be cropped.
There were also couple of similar questions on SO (for example and this GWT with Jcrop) but nobody gave an example of the selection part of the image that uses pure GWT.
If you have an idea how to do it please share and I'm sure other people will leverage from this in the future.
Here is the example of what I'm looking for:
I recommend that you take route #1. I've been working full time in GWT for awhile and spend a lot of time looking for libraries, and this is one that I just don't think exists yet.
Here are your options:
Wrap Jcrop using a JSNI interface.
Pros: You have to include JQuery and JCrop, which are small and robust
Cons: Learning how to build your first JSNI wrapper can be a pain
Build your own from GWT Drag and Drop
Pros: "Pure GWT"
Cons: You probably won't handle all the edge cases that JCrop has figured out over time, nor be as featureful.
Port JCrop to GQuery
Pros: JCrop is open source and only around ~1600 lines of code
Cons: It's ~1600 lines of code, which is likely to be much bigger when ported to Java
If you decide to do any of the above, please open source it! I'd be happy to contribute, and it looks like something that I could use in my GWT projects as well.
GWT Cropper is a widget that allows cropping an image.

What I am trying to do is to load a webpage into in a UIWebView. The problem is that I need to do some preprocessing on the html before displaying it in the web view.
The UIWebview loadHTMLString is quiet slow when the html is big. I don't need to display the full page therefore i am trying to remove some html nodes before displaying it in the web view to speed up the loading time.
I don't think using regex for that is a wise idea. I checked out NSXMLParser and TFHPPLE but I couldn't find any way to remove nodes from the html tree using an XPath or something.
I know I could do that using Javascript but that won't solve my problem. I also don't have no control on the website so I can't edit in the webpage itself.
Is there something as easy as deleteNodeUsingXPath or something :)
Cheers and thanks a lot for your help in advance.
One possibility solution: do a proxy website which strips out unwanted stuff. The iphone accesses the proxy website URL. The proxy website loads from the original website, strips out unwanted stuff, and replies with the remaining stuff.
There is a tool called Objective-C-HTML-Parser that will do what you are looking for. The documentation is thorough, and the implementation is pretty straight-forward.
Basically, you take your HTML string and make an HTMLParser object that you can then manipulate however you want. It is a very powerful library that basically lets you do whatever you want with HTML with easy-to-use Objective-C APIs.
Good luck!
