You’re looking for data serialisation. Popular choices that are robust are Sereal, JSON::XS and YAML::XS. Lesser known formats are: ASN.1, Avro, BERT, BSON, CBOR, JSYNC, MessagePack, Protocol Buffers, Thrift. Other often mentioned choices are Storable and Data::Dumper (or similar)/eval, but I cannot recommend them because Storable’s format is Perl version dependent, and eval is unsafe … Read more
Fragments do not have an onRestoreInstanceState method. You can achieve the same result in onActivityCreated, which receives a bundle with the saved instance state (or null). Check the source code here.
It’s best to have your plots in a list l = mget(plots) Then you can simply print them page-by-page, pdf(“all.pdf”) invisible(lapply(l, print)) dev.off() or save one plot per file, invisible(mapply(ggsave, file=paste0(“plot-“, names(l), “.pdf”), plot=l)) or arrange them all in one page, # On Windows, need to specify device ggsave(“arrange.pdf”, arrangeGrob(grobs = l), device = “pdf”) … Read more
If you are using Matplotlib and are trying to get good figures in a LaTeX document, save as an EPS. Specifically, try something like this after running the commands to plot the image: plt.savefig(‘destination_path.eps’, format=”eps”) I have found that EPS files work best and the dpi parameter is what really makes them look good in … Read more

I recommend you use shelve. For example: import shelve d = shelve.open(‘score.txt’) # here you will save the score variable d[‘score’] = score # thats all, now it is saved on disk. d.close() Next time you open your program use: import shelve d = shelve.open(‘score.txt’) score = d[‘score’] # the score is read from disk … Read more
You’re almost there. Using BitmapCacheOption.OnLoad was the best solution to keep your file from being locked. To cause it to reread the file every time you also need to add BitmapCreateOptions.IgnoreImageCache. Adding one line to your code should do it: imgTemp.CreateOption = BitmapCreateOptions.IgnoreImageCache; thus resulting in this code: uriSource = new Uri(Combine(imagesDirectoryTemp, generatedFileName), UriKind.Absolute); imgTemp … Read more
I know this question is 2 years old, but hopefully people will see this update. You can prompt the user to save an image in a base64 string (and also set the filename), without asking the user to do a right click var download = document.createElement(‘a’); download.href = dataURI; download.download = filename; download.click(); Example: var … Read more
The error regarding the file extension has been handled, you either use BMP (without the dot) or pass the output name with the extension already. Now to handle the error you need to properly modify your data in the frequency domain to be saved as an integer image, PIL is telling you that it doesn’t … Read more
