Incorrect result for some indicators using TA-Lib

I'm getting shifted "to past" result of some indicators when using TA-Lib.
Here it is incorrect shifted results: ( TEMA dark blue line is visible by a click/enlarge the picture )
TEMA indicator chart
Here it is correct results from Dukascopy:
TEMA indicator chart from Dukascopy
My Java source code for calculation indicators:
//initialization
double[] outRes = new double[array.length];
MInteger begin = new MInteger();
MInteger length = new MInteger();
//library call
Core c = new Core();
RetCode retCode = c.tema(0, array.length - 1, array, period, begin, length, outRes);
//result handling
if (retCode == RetCode.Success) {
return outRes;
} else {
System.out.println("Error in TEMA calculation");
return null;
}
Looks like bug in TA-Lib.
Does anybody encountered this problem? I heard before that there are forks of TA-Lib. Can anybody advise such forks or any other solution?

iTextSharp Footer Gets Progressively Bolder with Each Page

Using OnEndPage, I add a footer to my PDF created with iTextSharp. The footer font gets progressively bolder with each page.
How can I create consistent NORMAL fonts in my footer?
Here is my code:
public override void OnEndPage(PdfWriter writer, Document doc)
{
iTextSharp.text.Image gif = null;
if (FooterImage)
{
if (File.Exists(PathImages))
{
gif = iTextSharp.text.Image.GetInstance(PathImages);
gif.ScaleToFit(75f, 75f);
gif.SetAbsolutePosition(0, 0);
}
}
string sFooter = string.Empty;
if (FooterURL != null && FooterURL.Length > 0)
{
sFooter = FooterURL + " ";
}
if (FooterDate != null && FooterDate.Length > 0)
{
sFooter += FooterDate + " ";
}
if (FooterPage)
{
sFooter += "Page " + doc.PageNumber.ToString();
}
PdfPTable footerTbl = new PdfPTable(1);
footerTbl.TotalWidth = 900;
footerTbl.HorizontalAlignment = Element.ALIGN_CENTER;
Phrase ph = new Phrase(sFooter, FontFactory.GetFont(FontFactory.TIMES, 10, iTextSharp.text.Font.NORMAL));
PdfPCell cell = new PdfPCell(ph);
cell.Border = 0;
cell.PaddingLeft = 10;
footerTbl.AddCell(cell);
if (FooterImage)
{
PdfContentByte cbfoot = writer.DirectContent;
PdfTemplate tpl = cbfoot.CreateTemplate(gif.Width / 5, gif.Height / 5);
tpl.AddImage(gif);
cbfoot.AddTemplate(tpl, doc.PageSize.Width - 100, 10);
}
footerTbl.WriteSelectedRows(0, -1, 10, 30, writer.DirectContent);
}

In the old days, when there wasn't as much choice as today regarding fonts, people used workarounds to create bold fonts. One way to make a font bold, was by adding the same text over and over again at the same position. I think that this is happening to you.
When you use page events correctly, the onEndPage() method is triggered automatically each time a page ends. My guess is that you're doing something very wrong that triggers the onEndPage() many times. Maybe you are called the onEndPage() from your code, maybe you're adding the page event to the writer more than once (and page events are cumulative).
If I have to guess, I would guess that you are doing the latter. My guess is based on the fact that you are using variables such as FooterImage in your onEndPage() method. How are you setting that variable. If you are setting it in the constructor of the page event and you're adding the new page event over and over again to the writer, then you're doing it wrong.

JEditorPane remove border from image link

I have a JEditorPane that displays a link containing an image like so:
<a href='http://somesite.com/'>
<img src='someImage.png' />
</a>
When the JEditorPane display this as HTML, it puts a blue border around the image which I am trying to remove without any luck.
I want it to look like this inside of the jeditorpane:
image: (http://randomcloud.net/img/prob/valid.png)
But this is how the JEditorPane displays it:
image(http://randomcloud.net/img/prob/jeditorpane.png)
This is what I have tried so far, and it still is not working
editorPane = new JEditorPane("http://randomcloud.net/ads/index.php?id=1");
StyleSheet style = ((HTMLDocument)editorPane.getDocument()).getStyleSheet();
style.addRule("a img {text-decoration: none; border: none;}");
Any suggestions or insight ?

HTLEditorKit's ImageView source. As you can see borderSize is set to DEFAULT_BORDER (2 pixels). You can replace the ImageView creation in your implementation of ViewFactory and override the method to provide desired border (0 as I understand).
protected void setPropertiesFromAttributes() {
StyleSheet sheet = getStyleSheet();
this.attr = sheet.getViewAttributes(this);
// Gutters
borderSize = (short)getIntAttr(HTML.Attribute.BORDER, isLink() ?
DEFAULT_BORDER : 0);
leftInset = rightInset = (short)(getIntAttr(HTML.Attribute.HSPACE,
0) + borderSize);
topInset = bottomInset = (short)(getIntAttr(HTML.Attribute.VSPACE,
0) + borderSize);
borderColor = ((StyledDocument)getDocument()).getForeground
(getAttributes());
AttributeSet attr = getElement().getAttributes();
// Alignment.
// PENDING: This needs to be changed to support the CSS versions
// when conversion from ALIGN to VERTICAL_ALIGN is complete.
Object alignment = attr.getAttribute(HTML.Attribute.ALIGN);
vAlign = 1.0f;
if (alignment != null) {
alignment = alignment.toString();
if ("top".equals(alignment)) {
vAlign = 0f;
}
else if ("middle".equals(alignment)) {
vAlign = .5f;
}
}
AttributeSet anchorAttr = (AttributeSet)attr.getAttribute(HTML.Tag.A);
if (anchorAttr != null && anchorAttr.isDefined
(HTML.Attribute.HREF)) {
synchronized(this) {
state |= LINK_FLAG;
}
}
else {
synchronized(this) {
state = (state | LINK_FLAG) ^ LINK_FLAG;
}
}
}
I think the blue border is just selection of text. Try to deselect the content or use jEditorPaneInstance.getCaret().setSelectionVisible(false);

#Alien595: On img tags, you can add an attribute named border that is 0.
Example:
<a href="your_link.html">
<img border="0" src="your_image.png"/>
</a>

Xcode image link ImageView into next View Controller

I have made a Xcode project for a tabbed application that displays images of color swatches in a Scrollview. How do I link One of the images in my scrollview to go to the next View Controller? Below is my code and pictures. So when you click on one of the images or swatch color in the scrollview it links to the New Controller.
I have multiple images that scroll down the page of the iPhone, Do I have to loop the images cause there are 24 images. I was able to make one button and link it to the next scene with the interface builder, But I can fit 5 images on the screen..
DecorsViewController_iPhone.h
#import <UIKit/UIKit.h>
#interface DecorsViewController_iPhone : UIViewController
{
IBOutlet UIScrollView *scrollViewDecors;
}
#property (nonatomic, retain) UIView *scrollViewDecors;
#end
DecorsViewController_iPhone.m
#import "DecorsViewController_iPhone.h"
#interface DecorsViewController_iPhone ()
#end
#implementation DecorsViewController_iPhone
#synthesize scrollViewDecors;
const CGFloat kScrollObjHeight = 81.5;
const CGFloat kScrollObjWidth = 320.0;
const NSUInteger kNumImages = 24;
- (void)layoutScrollImages
{
UIImageView *view = nil;
NSArray *subviews = [scrollViewDecors subviews];
// reposition all image subviews in a horizontal serial fashion
CGFloat curXLoc = 0;
CGFloat curYLoc = 0;
CGFloat curYSpace = 1;
for (view in subviews)
{
if ([view isKindOfClass:[UIImageView class]] && view.tag > 0)
{
CGRect frame = view.frame;
frame.origin = CGPointMake(curXLoc, curYLoc);
view.frame = frame;
curYLoc += (curYSpace + kScrollObjHeight);
}
}
// set the content size so it can be scrollable
[scrollViewDecors setContentSize:CGSizeMake(([scrollViewDecors bounds].size.width), (kNumImages * kScrollObjHeight))]; // Vertical Option
}
- (void)viewDidLoad
{
self.view.backgroundColor = [UIColor viewFlipsideBackgroundColor];
// 1. setup the scrollview for multiple images and add it to the view controller
//
// note: the following can be done in Interface Builder, but we show this in code for clarity
[scrollViewDecors setBackgroundColor:[UIColor blackColor]];
[scrollViewDecors setCanCancelContentTouches:NO];
scrollViewDecors.indicatorStyle = UIScrollViewIndicatorStyleWhite;
scrollViewDecors.clipsToBounds = YES; // default is NO, we want to restrict drawing within our scrollview
scrollViewDecors.scrollEnabled = YES;
// pagingEnabled property default is NO, if set the scroller will stop or snap at each photo
// if you want free-flowing scroll, don't set this property.
// scrollView1.pagingEnabled = YES;
// load all the images from our bundle and add them to the scroll view
NSUInteger i;
for (i = 1; i <= kNumImages; i++)
{
NSString *imageName = [NSString stringWithFormat:#"Artwork_iPhone_Decors_Scrollview_%d.png", i];
UIImage *image = [UIImage imageNamed:imageName];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
// setup each frame to a default height and width, it will be properly placed when we call "updateScrollList"
CGRect rect = imageView.frame;
rect.size.height = kScrollObjHeight;
rect.size.width = kScrollObjWidth;
imageView.frame = rect;
imageView.tag = i; // tag our images for later use when we place them in serial fashion
[scrollViewDecors addSubview:imageView];
//[imageView release];
}

Firstly, you need to add a gesture recogniser to your view with something like:
UITapGestureRecognizer *singleTapGestureRecognizer = [[UITapGestureRecognizer alloc]
initWithTarget:self
action:#selector(flipView:)];
[singleTapGestureRecognizer setNumberOfTapsRequired:1];
[self.view addGestureRecognizer:singleTapGestureRecognizer];
You then need to implement the 'flipView' method:
- (void)flipView:(UIPanGestureRecognizer *)recognizer {
[self performSegueWithIdentifier:#"textView" sender:self];
}
As you can see in my case, when the method is triggered I perform a segue (see below):
- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:#"textView"])
{
//---Pass text to view
CGRect visibleRect;
visibleRect.origin = scrollView.contentOffset;
visibleRect.size = scrollView.bounds.size;
int number;
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
number = visibleRect.origin.x / 768;
}
else {
number = visibleRect.origin.x / 320;
}
TextViewController *textViewController = segue.destinationViewController;
AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
textViewController.text = [appDelegate.textArray objectAtIndex:number];
}
}
The 'number' variable is used to decide which image has been clicked, I divide the visible rects origin by the width of the screen in pixels to calculate which image has been pressed and therefore what data to send to my new view.
In your case, you would use the Y coordinate to perform a calculation to decide which colour has been pressed, possibly something like:
int number;
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
number = visibleRect.origin.y / <height of each image on iPad in pixels>;
}
else {
number = visibleRect.origin.y / <height of each image on iPhone in pixels>;
}
Alternatively, you could use a UITableView and just populate the cells with the appropriate colour and then display the new view based on which cell was pressed.
EDIT
Use a UITableView, and populate each cell with your image using custom tableview cells. This is a much easier approach than what you are suggesting.
See these links:
adding images to UItableView

You are overcomplicating this task massively, follow the above tutorials and you'll be done in no time. If this answer helped you, please mark it as correct.

You can customize your UIImageView. For example, MyImageView. Set its delegate to your main ScrollView and add UITapGestureRecognizer and TapDetecting Delegate methods.
You can implement in the MyImageView:
- (void)handleSingleTap:(UIGestureRecognizer *)gestureRecognizer {
// single tap
if ([_delegate respondsToSelector:#selector(myImageViewWasSingleTapped:)])
[_delegate myImageViewWasSingleTapped:self];
}
then in your main ScrollView(delegate of MyImageView):
- (void)myImageViewWasSingleTapped:(MyImageView *)miv {
AnotherViewController *asv = [[AnotherViewController alloc] initWithImage: miv];
[self.navigationController pushViewController: asv animated:YES];
[asv release];
}

You can use a button instead of a UIImageView, and set the button's image to your image. Your loop in viewDidLoad would be like this:
// load all the images from our bundle and add them to the scroll view
NSUInteger i;
for (i = 1; i <= kNumImages; i++)
{
NSString *imageName = [NSString stringWithFormat:#"Artwork_iPhone_Decors_Scrollview_%d.png", i];
UIImage *image = [UIImage imageNamed:imageName];
UIButton *imageButton = [[UIButton alloc] init];
[imageButton setImage:image forState:UIControlStateNormal];
[imageButton addTarget:self action:#selector(pushNextViewController:) forControlEvents:UIControlEventTouchUpInside];
// setup each frame to a default height and width, it will be properly placed when we call "updateScrollList"
CGRect rect = CGRectMake(0, 0, kScrollObjWidth, kScrollObjHeight);
imageButton.frame = rect;
imageButton.tag = i; // tag our images for later use when we place them in serial fashion
[scrollViewDecors addSubview:imageButton];
// Release imageButton unless you're using ARC
}
And then you'd need to define an action for imageButton, in this case I called it pushNextViewController:
- (void)pushNextViewController:(id)sender
{
UIViewController *yourNextViewController = // initialise your next view controller here
[self.navigationController pushViewController:yourNextViewController animated:YES];
}

How to display frame only when required & set frame to appear on top all the time?

My program will alert users when data (stock name & price) in the database matches with the data (stock name and price) from Yahoo Finance. With the help of HarryJoy i'm able to implement a pop up notification.
Problem is the pop up location on the screen is based on the database loop (int db). The frame will pop even if data doesn't match.
How can I set a counter or some method to pop up the frame only when database data = Yahoo Finance data? Also, my notification panels appears to be behind the main frame. How can make the panels appear on top of my main frame?
I hope I've given enough information, please ask if still unclear. Any guidance will be appreciated! Thanks!
In the database (using code sample only to display my explanation in order, source code below).
Object 1 = match
Object 2 = doesn't match (hence there's a gap)
Object 3 = match
Object 4 = match
Screenshot:
Code:
for (int db=0; db<= rowCount; db++)
{
Object popSymbol = table.getModel().getValueAt(db, 0);
String popupSymbol = popSymbol.toString();
Object popValue = table.getModel().getValueAt(db, 1);
String str = popValue.toString();
double popStockValue = Double.valueOf(str).doubleValue();
String stockNameDB = popupSymbol;
StockPara stock = YahooStock.getInstance().getStockPrice(stockNameDB);
double stockPriceDB = Math.round(stock.getPrice());
final JFrame popUpFrame;
final JPanel popupPanel;
if (stockPriceDB == popStockValue)
{
String header = "Stock: " + stock.getTicker() + " is now # " + stock.getPrice();
String message = "";
popUpFrame = new JFrame();
popUpFrame.setSize(320,90);
popUpFrame.setUndecorated(true);
popUpFrame.getContentPane().setLayout(null);
popupPanel = new JPanel();
popupPanel.setBorder(new LineBorder(new Color(0, 0, 0)));
popupPanel.setBounds(0, 0, 320, 90);
getContentPane().add(popupPanel);
popupPanel.setBackground(new Color(255, 255, 224));
popupPanel.setLayout(null);
popUpFrame.add(popupPanel);
// Other labels, images, etc.
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Insets toolHeight = Toolkit.getDefaultToolkit().getScreenInsets(popUpFrame.getGraphicsConfiguration());
popUpFrame.setLocation(screenSize.width - popUpFrame.getWidth(), screenSize.height - toolHeight.bottom - (popUpFrame.getHeight() * (db+1)));
}
}

To solve your issue quickly, simply create an additional counter (int counter = 0;). Then use that counter instead of db to position your popUpFrame and right after that increment counter.
int counter = 0; // Initiate outside de loop
...
for(int db=0; db<= rowCount; db++) {
...
if (stockPriceDB == popStockValue) {
...
popUpFrame.setLocation(screenSize.width - popUpFrame.getWidth(),
screenSize.height - toolHeight.bottom - (popUpFrame.getHeight() * (counter+1)));
counter++;
}
}
To bring your frame to the front use:
popUpFrame.toFront()
and to force it to be always on top (although I would really not recommend that because it is more annoying for the user than anything else):
popUpFrame.setAlwaysOnTop(true);
This is not necessarily supported by all platforms.

for on top issue, use
notificationPanel.requestFocus();
