How to expand a traineddata file in Tesseract? - tesseract

I want to add a new font to my language trained data file. I can build a new trained data file, and it works fine but is there any way that I could expand the old trained data file with the new one?

I have seen here someone seems to do it... I am not able to check it since I am on Windows...

Mbtiles to underlying dataset

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.

iTextSharp 5: Create image from text

I am using iTextSharp (C#) to generate a few PDF-reports.
One of them creates a bill. The bill must contain one line in OCR-B.
I cannot embed the font file.
Since im doing the new reports after the old ones, I went to check how it was done in the old bill-report. They inserted a picture.
Seems like a good workaround.
I have been googling on how to render text as image using iTextSharp, without success.
I am open for suggestions.
Apparently, there is no iTextSharp way of doing this.
This approach worked for me How to generate an image from text on fly at runtime
That way I didn't have to include any 3rd party libraries.

modify a template PDF using iTextSharp server side

So I'm brand spanking new to iTextSharp and I know I have quite a bit of reading ahead of me but in an attempt to shave a bunch of time off a relatively trivial task I thought I reach out the stack brain-trust.
I have a very simple goal: Starting with a template pdf, I need to create new pdf with a few of the characters changed. We're talking single characters on each page. I don't need a detailed answer complete with code (although that'd be awesome) so much as a general list of tools and api's I'm going to need.
The data I need will already be in a db which I could output to xml files if need be.
So far it looks like my template will need the "editable" characters tagged somehow (not sure how to do that yet) and using PDFStamper I can modify the copy. Is that the right path or is there a better way?
Thanks for any insight.

Perl how to add sheet into existing excel file which contains macros and formulas?

I have a problem with editing a file.
I'm using the module Spreadsheet::ParseExcel::SaveParser from CPAN.
The existing data in the file I want to add a new set of data and save the file as a new.
Unfortunately, the new file will not write a macro or formula.
Does anybody know how to solve this problem?
This is a limitation of Spreadsheet::ParseExcel, I believe.
You should be able to do it with Win32::OLE, which allows you to programmatically control Excel itself. See the first example in the documentation.

.des files not opening in xcode

I have a problem that i want to open and edit some images of .png extension that are currently in .des extension (for example button_start.png is in the form button_start.des) when i open button_start.des in the xcode it just show a text file like this(button_start.png 12234.00132330122309.that is now of image along with a long numerical number or possibly a hash code) i had been trying to open this .des file with many softwares like coreldraw and quickbooks but it still dont open.It had been weeks but still i am not finding any solution.please guys help me to solve this problem. thanks
.des-files are 3D-project-files. Xcode can't read nor see them, so you need to open them in the application they were created in and export them as PNGs.
If you added the .des-ending manually to a .png-file, you could simply rename the file file.png and it will work.
