imaging | Imaging is a simple image processing package for Go | Computer Vision library

After Microsoft apparently didn't find it necessary to implement the GDI+ components in a presentable way, I have solved the problem now completely differently and low-level.

Thanks to Bjørn for this excellent solution (it's a complete low-level Gif-Editor with UI): https://www.codeproject.com/Articles/1042433/Manipulating-GIF-Color-Tables?msg=5810217#xx5810217xx

The base64 value you provided in your question is malformed, my recommendation is to not use Json Serialization for this Api response effort.

Try using Convert.ToBase64String

• Ensure the method returns string
• and the jQuery request accepts/expects text for dataType response.

Set index, stack and unstack on the column name you need the values degenerated into columns

I was wrong thinking PdfiumCore is a binary provider package for PdfiumViewer. but it's an standalone package and as it uses a much newer Pdfium version (that seems to be a critical point for using pdfium) I decided to use it. (I also tested https://github.com/GowenGit/docnet and it worked fine but it use an older version of PDFium)

So used https://github.com/Dtronix/DtronixPdf/ (that is a thread safe implementation of PdfiumCore) and cleaned it to make a PDF To Image Converter from it and tested it on Windows and Linux. here's the final code: https://github.com/hmdhasani/DtronixPdf/blob/master/src/DtronixPdfBenchmark/Program.cs

Fascinating! The CIFaceBalance is actually not listed by the system as a "stand-alone" filter. (You can list all registered filters with CIFilter.filterNames(inCategories: nil)). So I guess it is intended to only be used auto adjustment filter with parameters set by the system. The parameters are also not really documented in its attributes dictionary...

However, it seems you can initialize it separately. The "image orientation" referenced in the documentation just means that you should make sure that faces in the image are aligned with the image's orientation (so they should not be on the side or upside down).
You can change the image orientation with image.oriented(.right), for instance, if needed. But Core Image should already orient images properly according to its metadata.

This class essentially does the same as the C# variant, without using temp files. The main method is only included as a usage example.

There's a TextChanged event on the TextBox that will run your code every time the text changes. Use that to disable the button.

A value like 145,55 which is stored in the column Cost is actually a string and not REAL, because it contains , as the decimal separator.

Do an update in the table to replace all occurrences of , to . in the column Cost and finally cast it to a REAL number implicitly by adding 0.0:

There is no need to specify any particular mapping for array values.

If you will not define any explicit mapping, then the rows field will be dynamically added as of the text data type

There is no data type that is defined for arrays in elasticsearch. You just need to make sure that the rows field contains the same type of data
