Tesseract supports the creation of sandwich since version 3.0. But 3.02 or 3.03 are recommended for this feature. Pdfsandwich is a script which does more or ... .NET 2.0 adds a new TextRenderer class (in the System.Windows.Forms namespace), which implements a slightly different model for text rendering. Essentially, the TextRenderer draws text using GDI (or Uniscribe for non-Western characters) rather than GDI+. There are a few reasons why you might prefer to use the TextRenderer instead of the standard Graphics.DrawString() method: The rendering quality for international text has been improved regularly. As a result, GDI draws better quality text than GDI+ when using these complex scripts. Similarly, if the Windows operating system is updated to support new languages, the GDI drawing methods will draw these scripts correctly while GDI+ likely will not, even with the correct font. The Windows Forms controls often use GDI. In some cases (possibly when extending one of these controls), you might want to draw text that matches exactly. If you use GDI+, the alignment and smoothing may differ subtly but noticeably. GDI+ locks font files for the duration of the application s lifetime, making it difficult to update fonts. Using the TextRenderer class is easy, as it exposes only two methods: MeasureText() and DrawText(), although there are multiple overloads of both. Here s an example that draws text using the TextRenderer when a Paint event fires: su = new SimpleUniverse(canvas3D); createSceneGraph(); initUserPosition(); // set user's viewpoint orbitControls(canvas3D); // controls for moving the viewpoint su.addBranchGraph( sceneBG ); } // end of WrapPlanets3D() The usual Canvas3D object has been replaced by a BGCanvas3D instance, which takes the background image filename (backFnm) as an argument. Since BGCanvas3D is a subclass of Canvas3D, it can be used in the same way as Canvas3D. The panel holding the canvas is set to be 512 512 pixels. The background image must have (at least) these dimensions in order to fill the canvas. createSceneGraph() constructs the lights, the background node, and the planets: //globals private static final int BOUNDSIZE = 100; private BranchGroup sceneBG; // larger than world tesseract ocr pdf to text c# How to use OCR to extract text from PDF in ASP.NET, C#, C++, VB ...
