Thanks to everyone in advance -

I cannot seem to figure out why I wouldnt receive multiple groups back from this match. I would assume I would receive:

[hello]
[john]


instead i am getting:

[hello]
[hello]

It seems like the regex stops after the first match is found, which leads me to believe that it has to do with some sort of flag -

String Format = "[hello] my name is [john]"; String RegexPattern = "(\\[.*?\\])"; Pattern MyPattern = Pattern.compile(RegexPattern, Pattern.CASE_INSENSITIVE | Pattern.DOTALL ); Matcher MyMatcher = MyPattern.matcher(Format); if(MyMatcher.find()) { for(int i = 0; i <= MyMatcher.groupCount(); i++) { out.print(MyMatcher.group(i) +"<br>"); } }


Thanks,

Sam

Thank you very much for the reply -


So I dropped in TYPE_INT_ARGB in and it gave me the error "java.io.IOException: Image can not be encoded with compression type BI_RGB", after looking into that a bit, I set the "getImageWritersByFormatName" to use PNG instead of BMP (I guess BMP doesnt support transparency, or it does, but no one ever implements it). This time though the image that I am overlaying colors were modified and the background is still black : )

Any suggestions?

Thanks,

Sam

I have created an image resizing class, with a crop method. The cropping works great, the issue that I am having is the background color that i specify in the drawImage function of Graphics is not working correctly, it defaults everything to black. Here is the code below that I am working with, I have also included the SaveTo method so you can see how I am saving as well

Thanks,

Sam


public void Crop(int Height, int Width, int SourceX, int SourceY) throws Exception { //output height and width int OutputWidth = this.OutputImage.getWidth(); int OutputHeight = this.OutputImage.getHeight(); //create output streams ByteArrayOutputStream MyByteArrayOutputStream = new ByteArrayOutputStream(); MemoryCacheImageOutputStream MyMemoryCacheImageOutputStream = new MemoryCacheImageOutputStream(MyByteArrayOutputStream); //Create a new BufferedImage BufferedImage NewImage = new BufferedImage(Width, Height, BufferedImage.TYPE_INT_RGB ); Graphics MyGraphics = NewImage.getGraphics(); MyGraphics.drawImage(this.OutputImage, -SourceX, -SourceY, OutputWidth, OutputHeight, Color.WHITE, null); // Get Writer and set compression Iterator MyIterator = ImageIO.getImageWritersByFormatName("BMP"); if(MyIterator.hasNext()) { //get image writer ImageWriter MyImageWriter = (ImageWriter)MyIterator.next(); //get params ImageWriteParam MyImageWriteParam = MyImageWriter.getDefaultWriteParam(); //set outputstream MyImageWriter.setOutput(MyMemoryCacheImageOutputStream); //create new ioimage IIOImage MyIIOImage = new IIOImage(NewImage, null, null); //write new image MyImageWriter.write(null, MyIIOImage, MyImageWriteParam); } //convert output stream back to inputstream ByteArrayInputStream MyByteArrayInputStream = new ByteArrayInputStream(MyByteArrayOutputStream.toByteArray()); MemoryCacheImageInputStream MyMemoryCacheImageInputStream = new MemoryCacheImageInputStream(MyByteArrayInputStream); //resassign as a buffered image this.OutputImage = ImageIO.read(MyMemoryCacheImageInputStream); } public void SaveTo(String DirectoryPath) throws Exception { if(this.ContentType == "image/gif"){ ImageIO.write(this.OutputImage, "gif", new File(DirectoryPath + this.ImageName)); } else if(this.ContentType == "image/jpeg"){ ImageIO.write(this.OutputImage, "jpg", new File(DirectoryPath + this.ImageName)); } else if(this.ContentType == "image/png"){ ImageIO.write(this.OutputImage, "png", new File(DirectoryPath + this.ImageName)); } else if(this.ContentType == "image/bmp"){ ImageIO.write(this.OutputImage, "bmp", new File(DirectoryPath + this.ImageName)); } else{ ImageIO.write(this.OutputImage, "jpg", new File(DirectoryPath + this.ImageName)); } }

Coming from other languages such as PHP, the DateTime object has max and min dates that the respective object will allow. For instance PHP's DateTime is:

$MinValue = "1901-12-13 20:45:54";
$MaxValue = "2038-01-19 03:14:07";

And C#:

DateTime.MaxValue
DateTime.MinValue

I have played around with calendars getMinimum/getMaximum methods and here is what I come up with

this is the minimum date - Thu, 1 Jan 0001 00:00:00 -0700 (does not change)

this is the max date - Wed, 17 Apr 292269054 21:34:07 -0700 (the second is constantly changing)

Am I on the right path or is there a better way to get max/min Calendar dates that are constant?


Thanks,

Sam
