            I've come across an issue of trying to fade the edges of the background image of a div so that it looks like it's blending with the background image of the full site (so the background image applied to the body).

            ANSWER

            You can use the background as gradient where the edges are rgba(0,0,0,0). This way it will smoothly blend with background. But this will not work for images. For images You will have to a div of background color and rgba(0,0,0,0) in gradient with color facing outward.

            General approach to parsing text with special characters from PDF using Tesseract?
            Asked 2021-Jun-15 at 20:17

            I would like to extract the definitions from the book The Navajo Language: A Grammar and Colloquial Dictionary by Young and Morgan. They look like this (very blurry):

            I tried running it through the Google Cloud Vision API, and got decent results, but it doesn't know what to do with these "special" letters with accent marks on them, or the curls and lines on/through them. And because of the blurryness (there are no alternative sources of the PDF), it gets a lot of them wrong. So I'm thinking of doing it from scratch in Tesseract. Note the term is bold and the definition is not bold.

            How can I use Node.js and Tesseract to get basically an array of JSON objects sort of like this:

            ...

            ANSWER

            Answered 2021-Jun-15 at 20:17

            Tesseract takes a lang variable that you can expand to include different languages if they're installed. I've used the UB Mannheim (https://github.com/UB-Mannheim/tesseract/wiki) installation which includes a ton of languages supported.

            To get better and more accurate results, the best thing to do is to process the image before handing it to Tesseract. Set a white/black threshold so that you have black text on white background with no shading. I'm not sure how to do this in Node, but I've done it with Python's OpenCV library.

            If that font doesn't get you decent results with the out of the box, then you'll want to train your own, yes. This blog post walks through the process in great detail: https://towardsdatascience.com/simple-ocr-with-tesseract-a4341e4564b6. It revolves around using the jTessBoxEditor to hand-label the objects detected in the images you're using.

            Edit: In brief, the process to train your own:

            1. Install jTessBoxEditor (https://sourceforge.net/projects/vietocr/files/jTessBoxEditor/). Requires Java Runtime installed as well.
            2. Collect your training images. They want to be .tiffs. I found I got fairly accurate results with not a whole lot of images that had a good sample of all the characters I wanted to detect. Maybe 30/40 images. It's tedious, so you don't want to do TOO many, but need enough in order to get a good sampling.
            3. Use jTessBoxEditor to merge all the images into a single .tiff
            4. Create a training label file (.box)j. This is done with Tesseract itself. tesseract your_language.font.exp0.tif your_language.font.exp0 makebox
            5. Now you can open the box file in jTessBoxEditor and you'll see how/where it detected the characters. Bounding boxes and what character it saw. The tedious part: Hand fix all the bounding boxes and characters to accurately represent what is in the images. Not joking, it's tedious. Slap some tv episodes up and just churn through it.
            6. Train the tesseract model itself
            • save a file: font_properties who's content is font 0 0 0 0 0
            • run the following commands:

            tesseract num.font.exp0.tif font_name.font.exp0 nobatch box.train

            unicharset_extractor font_name.font.exp0.box

            shapeclustering -F font_properties -U unicharset -O font_name.unicharset font_name.font.exp0.tr

            mftraining -F font_properties -U unicharset -O font_name.unicharset font_name.font.exp0.tr

            cntraining font_name.font.exp0.tr

            You should, in there close to the end see some output that looks like this:

            Master shape_table:Number of shapes = 10 max unichars = 1 number with multiple unichars = 0

            That number of shapes should roughly be the number of characters present in all the image files you've provided.

            If it went well, you should have 4 files created: inttemp normproto pffmtable shapetable. Rename them all with the prefix of your_language from before. So e.g. your_language.inttemp etc.

            Then run:

            combine_tessdata your_language

            The file: your_language.traineddata is the model. Copy that into your Tesseract's data folder. On Windows, it'll be like: C:\Program Files x86\tesseract\4.0\tessdata and on Linux it's probably something like /usr/shared/tesseract/4.0/tessdata.

            Then when you run Tesseract, you'll pass the lang=your_language. I found best results when I still passed an existing language as well, so like for my stuff it was still English I was grabbing, just funny fonts. So I still wanted the English as well, so I'd pass: lang=your_language+eng.

            Managing nested Firebase realtime DB queries with await/async
            Asked 2021-Jun-15 at 19:34

            I'm writing a Firebase function (Gist) which

            1. Queries a realtime database ref (events) in the following fashion:

              await admin.database().ref('/events_geo').once('value').then(snapshots => {

            2. Iterates through all the events

              snapshots.forEach(snapshot => {

            3. Events are filtered by a criteria for further processing

            4. Several queries are fired off towards realtime DB to get details related to the event

              await database().ref("/ratings").orderByChild('fk_event').equalTo(snapshot.key).once('value').then(snapshots => {

            5. Data is prepared for SendGrid and the processing is finished

            All of the data processing works perfectly fine but I can't get the outer await (point 1 in my list) to wait for the inner awaits (queries towards realtime DB) and thus when SendGrid should be called the data is empty. The data arrives a little while later. Example output from Firebase function logs can be seen below:

            Super hyggelig aften :)

            super oplevelse, ... long string generated

            Gist showing the function in question

            I'm probably mixing up my async/awaits because of the awaits inside the await. But I don't see how else the code could be written without splitting it out into many atomic pieces but that would still require stitching a bunch of awaits together and make it harder to read.

            So, two questions in total. Can this code work and what would be the ideal way to handle this pattern of making further processing on top of data fetched from Realtime DB?

            ListView is a widget that represents a list of widgets arranged linearly.

            You have multiple constructors for this widget. The one you used, ListView.builder() is the one suggested when there is a large number of children to be displayed. (In your example, if the Map contains many players.)

            The default constructor only requires a List and is considerably more simple. If you don't have a large map, I strongly suggest you to use this one instead. But since you tried using the builder one, you should do as follow:

            • First, have your data arranged in a List. This way you can access the elements through an integer index easily: List[0]. Ideally you should have the data already in a list form, but if you need you can convert it like this:

            VBA - NULL values in Listview
            Asked 2021-Jun-15 at 17:10

            I've created a simple VBA interface to connect Excel to a MySQL DB. The VBA part acts as a preview of data for the user to choose what item he wants to import to the Excel sheet.

            Until now I've work with a very complete set of data, but I got to a Table which (because of the nature of the items) some fields are NULL.

            Now every time I try to check the values in the VBA I get the Run-time error 13 Type mismatch in the listview component. At first I though it was a field with DECIMAL typing, but after changing it to a DOUBLE (for testing) the problem persisted, and it was until I notice that if only checks columns with no NULL value, the problem disappears. Off course I can't omit this values.

            I tried some .Tostring functions but with no success. And I failed to implement a IF to check for NULL in the obj.

            This question is related to Azure MSIX Build and Package task only has Release and Debug configurations

            We have a WinForms project that has an MSIX installer. Manually, we can successfully create

            1. An MSIXBUNDLE and deploy it to Kudu
            2. An MSIX and deploy it to an Azure VM through a VHDX. We have manually convert the MSIX to a VHDX first

            We are now trying to automate the build and release process to create the VHDX. However, we are getting a blank screen when the VHDX is mounted using a process that we have already validated. The only thing different is the build method (i.e., MSBuild versus VS Publish).

            Assuming you already have Redis installed:. Or add the gem to your Gemfile. If you are using Rails, add the above to an initializer. If Redis is running on localhost and on the default port the second line is not needed.
            It is easy to use Related in a distributed cluster setup. As of writing this (November 2011) Redis Cluster is not yet ready for production use, but is expected for Redis 3.0 sometime in 2012. Redis Cluster will then be the preferred solution as it will allow you to setup up a dynamic cluster that can re-configure on the fly. If you don’t need to add or remove machines for the cluster you can still use Related in a distributed setup right now using the consistent hashing client Redis::Distributed which is included in the "redis" gem. The regular expression supplied in the :tag option tells Redis::Distributed how to distribute keys between the different machines. The regexp in the example is the recommended way of setting it up as it will partition the key space based on the Related ID part of the key, in effect localizing all data directly related to a specific node on a single machine. This is generally good both for reliability (if a machine goes down, it only takes down a part of the graph) and speed (set operations on relationships originating from the same node can be done on the server side, which is a lot faster, for example). You could also specify a regexp like /:(n|r):/ that will locate all relationships on the same machine, making set operations on relationships a lot faster overall. But with the obvious drawback that the total size of your graph will be limited by that single machine.
