I am trying to extract and save a google map image from the internet using a URL so as to try and extract some data out of it.
Appreciate any sort of suggestions or help regarding this matter.
Thanks !
You can pass a URL of an image file into imread. However, you cannot read in an html document as an image into MATLAB directly.

I have a .mbtiles and would like to convert it back to a dataset so I can edit it.
I don't see a convert/export button for this function on mapbox studio or maptiler.
Any help would be great thanks.
You could try using a tool like https://github.com/mapbox/mbtiles-extracts .
In general it's a problematic, lossy process, and you're better off trying to get the original source data from somewhere else.
After parsing a media, libVLC libvlc_media_get_meta does returns libvlc_meta_ArtworkURL as :
attachment://picture0.jpg.
Could someone help shed some light on how to extract the image data to let say, export the image data as an external file? I'm simply interested on how to access the image data here.
Thank you,
Okay so I want to load a image from a URL in my app, however this image will need to be updated every month manually, therefore its not practical to have to submit a new update to apple every time the url changes. So does anyone no of a picture/file sharing site that would allow me keep the same URL for the image even when uploading a updated version of the image?
You can just use the same url for the image that you want presented hosted on your domain or a hosting site.
So something like
http://www.mydomain.com/appImage.jpg
That you always call to and always is the address of the relevant image. Basically the URL is just a location that you can store any image at.
Up to my knowledge, in order to achieve this you will need a static URL. So that means you'll have to buy a domain from a hosting service.
Or if not you can use Google Drive for this. But you'll have to do some more coding for this.
Try using Google Drive:
Upload a text file(*.txt) to your Google Drive and get a shareable link. Convert it to a direct download link.
Next save whatever your image as a String (base64); I have attached some interesting coding examples below.
Then give the file link to your app; download the file; read the String(base64) convert it back to image format.
When you want to update the Image convert it to a String; open the Google Drive; edit your file using Drive Notepad (Do not use
Google Docs) and simply save it Ctrl+S.

I have developed a pdf reader using schwa/iOS-PDF-Reader API. I am experiencing a caching problem, I supply my file path dynamically to the API, but the reader always brings up the first pdf file irrespective of the file path supplied.
Please help me out..
Thanks in advance...
You can give all pdf paths into an array and then just pass array index path to your API.
Just try it i hope it will help for you.
I want to take a photo or pick a picture from iphoto library and then upload it to webserver.
Use imagePickerController I can only get a UIImage Object,I can't know it's file path or file type(png,jpg,etc.). I have google for a long time but still can't find a solution. Any one can help me? Thank You!
You need to get the raw data from the image. Take a look at questions like this one.
Then, just set the appropriate MIME type on your http request and shoot the data up to the server.
