gofile | Provides a generic interface to filesystems in Go | File Utils library

Finally I managed to do this, and I will explain how so that someone can use it too.

First of all i removed every "non data" character and used spaces as a separator. Then i opened the file in R by inserting it ina 768 columns long dataframe (3 vlaues x 256 pixels), with NA for every missing value.

The parsing is done by chosing every third column starting from the 1st (for X), from the 2nd (for Y) and 3rd (for VALUE).

As discussed in the comments, the image had a .jpg extension in the name, but was a PNG image file. The PDImageXObject createFromFile(String imagePath, PDDocument doc) method assumes the file type by its extension, so it embedded the file 1:1 in the PDF and assigned a DCT filter. Both of these would have been correct for a jpeg file, but not for png.

So the solution would be to either rename the file, or use the createFromFileByContent method.

Your raster is simply almost empty, in the sense that it has just the 2% of values !=0. However if you export the raster and visualize it in a GIS software (like Qgis, or ArcMap), by setting a 100% transparency for the 0 values you can see the remaining values:

Here an example:

In order to serve the static files from a container using the nginx proxy, the nginx proxy must have access to files statically... it would not 'proxy' but 'read' and serve the files... which means you must mount the app files into the proxy...

I would recommend you put up a new, light and clean nginx behind the nginx proxy along with your php-fpm service so you can have full management of your routes/locations,

First of all I have created a docker-compose.yml in my app that contains the following:

I can't seem to find an answer directly filtering spark dataframe using %in% operator based by vector matchings.. so I had to make a custom function by filtering directly from SQL, which is look like this:

Try changing the urls in your html code from stuff like

The problem you have is a conflict between:

• zooming and dragging the image inside the custom ClipPath
• dragging the images between two custom ClipPath

The solution I propose is to use drag handles to swap the images

!!! SPOILER : It does not work (yet) !!!

To implement this drag-n-drop with custom ClipPath, we need the support of HitTestBehavior.deferToChild on DragTarget.

The good news is... It's already available in Flutter master channel! [ref]

So, if you can wait a bit for it to be released in stable, here is my solution:

The main idea is to have the zoomable images as DragTargets and for each image a drag handle as Draggable.

I added a layer of State Management to keep the zoom level and offset when swapping the images.

I also improved the zoomable feature to ensure that the image always covers the full ClipPath.

Use the following technique to achieve your effect – override didHighlightItemAt and didUnhighlightItemAt in your collection view delegate like so:
