Loading command is taking lot of time to load the file. Is there anyway to improve this performance. Please advice its urgent!!! Herewith I have attached text file which I used for testing. Please find Code: ----- string _loadFile = @"C:\LeadTools.txt"; RasterCodecs _codecs = new RasterCodecs(); _codecs.Options.Txt.Load.Enabled = true; _codecs.Options.Txt.Load.TopMargin = 1; _codecs.Options.Txt.Load.BottomMargin = 1; _codecs.Options.Txt.Load.LeftMargin = 1; _codecs.Options.Txt.Load.RightMargin = 1; _codecs.Options.Txt.Load.FontColor = new Leadtools.RasterColor(System.Drawing.Color.Black); _codecs.Options.Txt.Load.FontSize = 12; _codecs.Options.Txt.Load.Bold = false; using (Leadtools.IRasterImage image = _codecs.Load(_loadFile)) { string filename = ""; Leadtools.RasterImageFormat format = Leadtools.RasterImageFormat.TifCcittGroup4; int bpp = 1; int firstPage = 1; int lastPage = image.PageCount; int firstSavePageNumber = 1; Leadtools.Codecs.CodecsSavePageMode pageMode = Leadtools.Codecs.CodecsSavePageMode.Append; for (int i = 1; i <= lastPage; i++) { filename = @"C:\Tiff_Images\img"+i.ToString()+".tif"; _codecs.Save(image, filename, format, bpp, i, i, i, pageMode); } } It will be greatly helpful if you can provide some sample code to improve the performance. Note: I am using Leadtools version 14.5.0.68 and C# 2008. Thanks, Ganesh.    Report

Hi Ganesh, For some reason the TXT file didn't get attached.  How big is the text file?  Try setting the _codecs.Options.Load.XResolution and _codecs.Options.Load.YResolution to 150, and then 300 to see how long the loading times are. How many pages does the TXT file have?  Call _codecs.GetInformation() before calling _codecs.Load() to find out how many total pages there are. LEADTOOLS Technical Support    Report

I tried calling _codecs.GeInformation() before calling _Codecs.load(). It seems, text file contains 2000+ pages. Could you please provide some way to improve the file load performance. Thanks Ganesh.    Report

Loading TXT files is a CPU intensive process because TXT files are vector files and they have no explicit page separators.  So you can load a certain number of pages at a time.  You can specify the first and last page parameters of the codecs.Load() method.  You can load pages 1-10, 11-20, etc., in blocks.  See how that works out for you.

Is it possible to get a stream for a particular page or is it possible to identify how many lines we can print for each page(including wordwrap)? If you have any sample code to acheive the above please send. Thanks, Ganesh.    Report

07-01-2008, 12:07 jigar Joined on 08-22-2007 Posts 480 Re: Text file loading is taking long time...Please help!!! You can calculate it to an approximate value.  Knowing the dpi and font size of the image, as well as the page margins, you can calculate how many characters you can fit in one page. Have you tried loading one page at a time?  Like: RasterCodecs.Load("file.txt", 0, CodecsLoadByteOrder.BgrOrGray, 1, 1).  The last two parameters are equal and you increment them by 1 for each page.

I tried loading single page(as you suggessted) and save them, for 1hour it just converted only 29pages only... Could you please give some sample to calcuate the content per page based on the below code... _codecs.Options.Txt.Load.Enabled = true; _codecs.Options.Txt.Load.TopMargin = 1; _codecs.Options.Txt.Load.BottomMargin = 1; _codecs.Options.Txt.Load.LeftMargin = 1; _codecs.Options.Txt.Load.RightMargin = 1; _codecs.Options.Txt.Load.Bold = false; _codecs.Options.Txt.Load.FaceName = "Arial"; _codecs.Options.Txt.Load.FontSize = 10; _codecs.Options.Txt.Load.FontColor = new RasterColor(System.Drawing.Color.Black); _codecs.Options.Load.XResolution = 150; _codecs.Options.Load.YResolution = 300; because some of the line in the text file are longer one so while converting image it coming as 2lines(word warp) sometime morethan 3times... It will be greatly helpful if you can provide some sample. Also I am getting one error message while loading text(even 2kb) file...

What build version is your Leadtools.Codecs.Txt.dll file?  I'm trying load a simple 4 byte text file and it's throwing a null reference error for me with default settings.  I'm running 14.5.0.77.  Also zip up the 2kb file that fails on you and attached it to your post.  I want to try that one out too.

"Attempted to read or write protected memory" is thrown by the .NET framework.  If you are trying to read from a Stream object you can get this for any number of reasons.  Are you trying to load the TXT file into a MemoryStream and then load it with codecs.Load()?  Make sure you can read from the Stream object you are using.  Try calling the ReadByte() method and see if that throws an error.

Loading a page 1 at a time is slower overall, as opposed to loading 10 pages at a time.  For me it takes 60 seconds to load 10 pages, and 68 seconds if I load those 10 pages one by one.  60 seconds for 10 pages is expected since text files need to be rasterized.
