Looking for a component, dll, etc, for OCR for a VB.NET program. Using VS PRO 2008.
The source is a bunch of small png images, and I am just getting a price out of them. Very simple.
Tried tessnet2, but could not get png to work. Don't mind commercial, but not too expensive - maybe about $100. Want something simple to use and preferably with support if needed. This is for a commercial application.
Thank you!
Microsoft Office 2003 onwards (Or Word 2003+) comes with something called Microsoft Office Document Imaging (MODI) Its a COM component you can use to perform ocr.
See this:

And I also bumped into this:
http://weblogs.asp.net/jgalloway/archive/2006/10/01/Free-OCR-software_3F00_-You-may-already-have-it_2E002E002E00_.aspx
The downside of course would be needing office installed I think.
Got tessnet2 to work with png. png was not working because of the transparent background. Made a second image with a background color contrasting the text color, and drew the original image on top of that. The second image ocr'd perfectly.
Would still be interested in a commercial ocr not too expensive, but this works now.
Thank you for your replies!

I'm trying to make an image file from a control using CopyFromScreen, and it fails unless I set the scale to 100%. With a larger scale the image is progressively offset left and up, the further right and down the window is on the screen. (Unfortunately my eyes struggle at 100%)
I initially tried using DrawToBitmap but that fails as there's a rich text box in the control and it's documented that that won't paint.
I've read articles on this forum and followed the suggestion of including the dpiAware setting in the manifest, but that has no effect. I'm no expert and I'm wondering if it's because I only have VS 2012 and my manifest declaration starts with asmv1 rather than asmv3 so I had to amend the example code?
Any suggestions most welcome.
I was recently asked to do some research on some third party HTML editors to be embedded into our current software (Which is built in VB).
I began doing some research, but no luck.
I don't know much about building HTML editors, but is this something that can easily be done?
From what I've been told, I need something like CKEditor, but not for web use.
Thanks
My quick search:
Microsoft WinForms HTML Editor

TX Text Control
Definitely what I was looking for
I just installed Visual Basic 2010, went through some tutorials on how to display files, but can't find any material on how to select and embed existing PDF files into a form. Any suggestions or pointers in the right direction would be great, thanks!
Just embed a browser control in your form and navigate that to the PDF file. That should do the trick.
There aren't too many out of the box controls for that. Anyway, this guide might be helpful:

Disclaimer: I work at Atalasoft.
We make a GUI control that can load a bunch of image formats, and an add-on to turn PDF pages into images. The GUI control (ImageViewer) is part of our free SDK (DotImage Photo) and you can learn about the add-on here: http://www.atalasoft.com/products/dotimage/pdf-reader
I am working on generating a document for printing. It should use a specific TTF font and everything must be printed with vector graphics (for quality). Some of the text should be replaced automatically (e.g. current time). Also it should include a custom-generated EPS image with a chart.
Ideally I would like to have some kind of document template where the text could be replaced easily, and it would be nice if it could import the image through path. But I am not sure which format could be good for this. Best I can come to think of is LaTeX, but I don't like that it's a lot of manual work to use it with TTF... any other ideas?
By the way, I am using OS X...
Memoir package is very flexible for your special layouts.
Xetex uses your system fonts (Installed together with TexLive).
You could blend most of those elements to an EPS using imagemagick or gimp script-fu
There are several products out there that will build you a PDF programmatically. I've only used the Coldfusion Report Builder myself and that may not be practical/affordable for your application. If your budget allows I'd look into a commercial reporting product. I know Adobe have several that will generate Flash, FlashPaper or PDF output.
I am trying to identify the right tool, language, software package, or other for the automated development of presentations, where the presentation is user interactive.
The presentation will consist of images with titles and some descriptive text. Most of the time there will be 35–70 images. I would like to show each image on a separate page, slide, tab, etc. (I guess proper terminology depends on the solution.)
The images will change, but the titles will remain the same, and there will be a little bit of change to the description of each image.
After putting the presentation together, I would like the user to be able to circle and "write" on the electronic image in kind of the wax pencil sense (I previously worked in a photo lab and we worked with wax pencils on negatives all the time and would like to have kind of a similar flexibility). Moreover, I would like users to be able to add comments as well, kind of in the way Adobe PDF Professional allows, e.g. inserting bubble comments, etc.
Most importantly, I would like to be able to do this in an automated way. Right now we are using PowerPoint, but the amount of time it is taking to put an image on a slide in PowerPoint, resize it, and then set up the text is killing us. Plus, as the images change it takes tons of time to go back and update them. Thus, we would like something that is a bit faster to update images and get the feedback from our few users. Does not necessarily have to be a web hosted solution, but could be run through a browser.
Sorry this is so long and thanks for any ideas and feedback, especially if there is an existing software package solution, language that can be used, or other approach to get this done.
These days, two of the most popular are Adobe Captivate and Articulate Presenter. For service, instead of product, you can check out services like http://voicethread.com.
I don't know of any product that completely answers your requirements.
But, for similar results I use two different tools for developing the presentations and another one for drawing while presenting.
If I just want to make a presentation made of pictures and texts, and I want to automate its creation, I use irfanview http://www.irfanview.com/ with its wonderful feature for automated slideshows. I put all the images together, annotate them (I use either their filenames, or if not enought, with EXIF and comment fields) and create a slideshow, that can be compiler into an .exe file.
If I want a more elaborated presentation. With full annotation capabilities, I use Wink http://www.debugmode.com/wink/
For drawing over the screen during the presentation, I use a very old bitmap drawing program, called PC-Draw, that allows, with a hotkey, to capture the screen as a bitmap and begin drawing over it, and with another hotkey, to return to the original screen without altering the running programs at all. I have not found it anywhere in the web. However, I found similar programs just a quick google away.
All three tools are free and easy (and even fun) to use.
