Thread.Sleep(TimeSpan.FromSeconds(cancelCheckInterval)); } } // Use the forced approach. thread.Abort(); } You could use a similar approach to implement the Pause() and Resume() methods. The next refinement is progress tracking. If your derived class supports progress reporting, it should set the SupportsProgress property to true. It can then supply the percentage complete through the protected progress variable. private bool supportsProgress = false; protected bool SupportsProgress { get { return supportsProgress; } set { supportsProgress = value; } } protected int progress; public int Progress { get { if (!supportsProgress) throw new InvalidOperationException( "This worker does not report progess."); else return progress; } } You ll see progress reporting in the next example. tesseract ocr pdf to text c#: How to Extract Text From Scanned PDFs using C# - YouTube tesseract c# pdf The C# OCR Library | Iron Ocr - Iron Software

One improvement would be to implement some form of task queuing. This approach prevents the possibility that the user might start a huge number of threads running simultaneously, ensuring that none can get enough system resources to finish their work (a problem known as thread starvation). Instead, you allow only a set number of threads to work at once. Once you reach the limit, you add any additional requests to a queue and execute them only when a thread becomes available. To manage this work, you need to replace the simple collection of worker threads (from the previous example) with a dedicated class that wraps the queuing and thread management work. This model requires too much code to show it all here, but you can see the complete code in the downloadable examples for this chapter. add watermark to pdf c#: Watermark pdf in C# - asp.net tips and tricks tesseract ocr pdf to text c# NuGet Gallery | Pdf.Ocr 4.4.4.1

IronOCR and Tesseract Comparison for . When getRotatedImage() is given a BufferedImage and an integer angle, it creates a new BufferedImage rotated by that number of degrees in a clockwise direction. The image s center is used as the center of rotation: private BufferedImage getRotatedImage(BufferedImage src, int angle) { if (src == null) return null; int transparency = src.getColorModel().getTransparency(); BufferedImage dest = gc.createCompatibleImage( src.getWidth(), src.getHeight(), transparency); Graphics2D g2d = dest.createGraphics(); AffineTransform origAT = g2d.getTransform(); // save original transform // rotate the coord. system of the dest. image around its center AffineTransform rot = new AffineTransform(); rot.rotate( Math.toRadians(angle), src.getWidth()/2, src.getHeight()/2); g2d.transform(rot); g2d.drawImage(src, 0, 0, null); g2d.setTransform(origAT); g2d.dispose(); return dest; } // end of getRotatedImage() // copy in the image tesseract ocr pdf c# Tesseract OCR C# - YouTube

Indexes greatly increase search operations on the database, but they slow down operations that change the database (delete, update, and insert operations). Having too many indexes can slow down the general performance of the database. The general rule is to set indexes on columns frequently used in WHERE, ORDER BY, and GROUP BY clauses, used in table joins, or having foreign-key relationships with other tables. Indexes are automatically created on primary key and unique table columns. You can use dedicated tools to test the performance of a database under stress conditions with and without particular indexes; in fact, a serious database administrator will want to make some of these tests before deciding on a winning combination for indexes. You can also use the Database Engine Tuning Advisor, which can be accessed through SQL Server Management Studio (the tuning advisor doesn t ship with Express Edition, however). Consult a specialized SQL Server book for more details on these subjects. In your application, you ll rely on the indexes that are automatically created on the primary key columns, which is a safe combination for our kind of web site. Note You can also use the ThreadPool class from the System.Threading namespace for a simple implementation of thread queuing that uses threads from the CLR s pool. However, the ThreadPool doesn t give you much flexibility for example, you can t stop tasks, report progress, control how many tasks execute at once, and change priorities. However, the ThreadPool implementation is still better than the example you ll consider in this section in one respect. Because it reuses threads for more than one task, you avoid the overhead of creating new threads. A tricky aspect of getRotatedImage() is that the affine transformation employs the original image as a clipping rectangle. If the rotation takes the picture outside those bounds, it ll be clipped, as illustrated by Figure 8-11. c# ocr pdf to text [Solved] C# code to extract text from a scanned pdf document ...
