Read data from a Gif

i have a requirement to read data from a gif. The gif is exported from a Bloomberg terminal and contains Stock Prices. Is there anyway of reading the Stock Prices off开发者_开发百科 this gif?

I'd prefer to do it in C#, but if there is any other programming language that is recommended, i would be grateful if you can share that with me.

regards

A GIF is a graphic file. The only way to read data from it would be to use some form of OCR.

These software packages/libraries usually aren't free, but you could look at FreeOCR and try out what's there. Or look at the Tessnet2 Tesseract .NET library (most of the free/open source OCRs use the Tesseract engine).

I also feel compelled to point out that this is probably violating some sort of license agreement or TOC. Even if it isn't, you'd have a hard time guaranteeing any sort of accuracy for the information, and inaccuracy is an extremely bad thing when you're talking about stock prices. Be careful.

This sounds very dodgy to me. You would have to:

1. Have a high enough resolution such that optimization of the gif doesn't cause you to loose accuracy
2. You would have to use edge and corner detection to re-plot the time series / line from the gif. This is inherently inaccurate
3. You would have to now relative price/time for the gif dimensions. If this changes between gifs then forget it. Reading the values on the side/bottom would be a nightmare.

In short, find another source of data would be my recommendation. Image analysis on a gif to produce financial information isn't exactly a FIX update
