Java Forum / General / August 2005extract text from screen or screenshots...
Is there a way to extract or search for text on a computer screeen? I have a java program that caputures the screen shots of a constantly changing database log file and saves the screen shots as .png or .jpeg files. I need to search for a particular value, "timeelapsed" from the screenshots -- is there any way to do this? Another method would be to have a java program to read the text from the screen directly without having to go through screenshots. Is this possible to do? Thank you very much. > Is there a way to extract or search for text on a computer screeen? > > I have a java program that caputures the screen shots of a constantly > changing database log [1] >..file and saves the screen shots as .png or .jpeg > files.

It would be far easier (generally) to search the database log itself. Where is it?

[....] > [ To continue with your current folly, Google 'OCR'. ] More specifically google Screen+OCR. Also look up CopyText.exe . Google results for Windows+Controls+Clipboard brings up some utilities. The log files are the output of a customized java application, not one generated by the database itself. The java application writes messages to the screen when data is updated or deleted from the database. The data on the log screen keeps updating constantly hence the need for screen images. Thank you very much for the OCR information - wonder if there are any sample source codes to implement this in java? ============================================ > > Is there a way to extract or search for text on a computer screeen? > > [quoted text clipped - 20 lines] > physci.org 1point1c.org javasaver.com lensescapes.com athompson.info > Secreted by the Comedy Bee > The log files are the output of a customized java application, not one > generated by the database itself.

Thank you very much for the OCR information - wonder if > there are any sample source codes to implement this in java? Where is the java application writing messages? To the console? In that case pipes are perhaps more appropriate. Pipe the java programs output to another program which can parse the data and store for future reference and also output all of its input to the console. > The log files are the output of a customized java application, not one > generated by the database itself.

Forget the OCR, and please stop changing the 'Subject' line, as it breaks normal threading behaviour in some news clients[1]. It is (probably) going to be orders of magnitude simpler to intervene directly in the Java application for your data. Give us more information on it. Who wrote it, where is the source?
