To do this I took a sample code from github and tried it in my local Eclipse Setup. import java.io.File; import java.io.FileNotFoundException; import javax.xml.bind.JAXBException; import org.docx4j.convert.in.xhtml.XHTMLImporterImpl; import org.docx4j.openpackaging.exceptions.Docx4JException; import org.docx4j.openpackaging.exceptions.InvalidFormatException; import org.docx4j.openpackaging.packages.WordprocessingMLPackage; import org.docx4j

I create Image objects from files, the problem is that when I convert 9 png files(each 50kb) to gif, it taks only 50ms. but when it turns to 9 jpg files (each 20kb), it takes 1900ms. What is the reason behind? How can I make it faster with jpg files? for(int i = 2; i < argc-1; i++) { // I pass the file path from command line cout << argv[i] << endl; Image img(argv[i]); img.animationDelay(delay); img.magick("GIF"); frames.push_back(img); } long

I have tried using queries like: ALTER TABLE mytable ADD COLUMN mycol_tmp oid; UPDATE mytable SET mycol_tmp = CAST(mycol as oid); ALTER TABLE mytable DROP COLUMN mycol; ALTER TABLE mytable RENAME mycol_tmp TO mycol; But that just gives me the error: ERROR: cannot cast type bytea to oid Is there any way to achieve what I want? 回答1: A column of type Oid is just a reference to the binary contents which are actually stored in the system's pg_largeobject table.

I'm looking for a simple format cell function such as =Hex2b64(Hexstring) that will accept any length of hex characters. I have found pieces here and there but no one simple code block. I have been using http://home.paulschou.net/tools/xlate/ in order to do my conversion manually up to this point. The conversion works well and the data is received by all relevant databases and parsed appropriately. The data I am receiving is hex represented binary, which has been

So let's write it! private static System.Array ToSystemMatrix<T>(ILInArray<T> A) { using (ILScope.Enter(A)) { // some error checking (to be improved...) if (object.Equals(A, null)) throw new ArgumentException("A may not be null"); if (!A

Why? result = line * 2 print type ( line ) #prints as string? print type ( result ) #prints as string? print " Entered value times two is " , result print 'Done! Enter to close' As far as I can tell, it should be working fine.The issue is that when I input a value, for example 6, I receive 66 instead of 12. It seems like this portion of code:

String date = "03-05-2013 00:00:00"; I parsed it to Datetime as follows: DateTime Start = DateTime.Parse(date); Start.ToString() gave me "3/5/2013 12:0:00 AM" I also used: DateTime Start = DateTime.ParseExact(date,"dd-MM-yyyy HH:mm:ss",CultureInfo.InvariantCulture); Then, Start.ToString() gave me "3/5/2013 12:0:00 AM" , which is the exact same result as the previous one. I need to keep the original formatting. How may I do it? Thanks. 回答1: The format you parse with does not dictate how the
