resize or scale UIImage

hi,

we can scale the UIImage to any size using the follwing method

add this code to your .h file

@interface UIImage (INResizeImageAllocator)
+ (UIImage*)imageWithImage:(UIImage*)image
              scaledToSize:(CGSize)newSize;
- (UIImage*)scaleImageToSize:(CGSize)newSize;
@end

add the following to .m file


@implementation UIImage (INResizeImageAllocator)
+ (UIImage*)imageWithImage:(UIImage*)image 
              scaledToSize:(CGSize)newSize;
{
    UIGraphicsBeginImageContext( newSize );
    [image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
    UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    
    
    return newImage;
}
- (UIImage*)scaleImageToSize:(CGSize)newSize
{
    return [UIImage imageWithImage:self scaledToSize:newSize];
}

e.g to resize an image

self.resizeimage = [UIImage imageWithImage:actual_image scaledToSize:CGSizeMake(65.0f, 65.0f)];

UIWebView : load local html file

see this post

Formatting UITextView

There is no feature to format the text in UITextView

We can use the UIWebView to display the formatted text

The easy two methods are :

1. - (void)loadHTMLString:(NSString *)string baseURL:(NSURL *)baseURL

2. - (void)loadRequest:(NSURLRequest *)request

1.
use the html formatted text as input.
e.g:

NSString *htmlText = @"<html><head><meta name=""viewport"" content=""width=320""/></head><body><h3>Header</h3><p>Just for testing n;</p></body</html>";

[webView loadHTMLString:htmlText baseURL:[NSURL URLWithString:@"http://www.apple.com"]];

2. Or we can load a local html file
e.g:

[webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"]isDirectory:NO]]];

Dynamic Height for UITextView / UILabel / UITableViewCell

we can use this for calculating the height taken by a UILabel or UITextView or we can use this same method to calculate the height of cell according to its content..

CGRect frame1 = CGRectMake(5.0, 100.0, 300.0, 75.0 );
    UITextView *textView = [[UITextView alloc] initWithFrame:frame1];
    textView.font = [UIFont systemFontOfSize:17.0];
    NSString *str  = @"The Lord takes care of me as his sheep; I will not be without any good thing.";
    CGSize        textSize = { 300.0f, 9999.0f };
    CGSize size1 = [str sizeWithFont:textView.font constrainedToSize:textSize lineBreakMode:UILineBreakModeWordWrap];
    textView.text = str;
    frame1.size.height = size1.height;
    textView.frame = frame1;
    [self.view addSubview:textView];
    [textView release];

For UITableView
we can use like

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

{

//calculate the height of the text displayed on this cell using the above method

return MAX(size1.height, kMinRowHeight);

}

PIT Solutions extends Blue Brain association

Technopark based PIT Solutions to partner Blue Brain Project

THIRUVANANTHAPURAM: PIT Solutions based at the Technopark in Thiruvananthapuram, which focuses on IT solutions to the small and medium sector, has extended its comprehensive IT support to the Blue Brain project.

The project is the first comprehensive attempt to reverse re-engineer the mammalian brain in order to understand brain function and dysfunction through detailed simulations.

PIT Solutions will continue to partner Dr Henry Markram, director of the Swiss Federal Institute’s (EPFL) Brain Mind Institute, for the Blue Brain project. Dr Markram said the mysteries of the mind could be solved, and that it was possible to have a supercomputer that models all the brain’s 100 trillion synapses.

The project attempts to build a computerized copy of a brain, starting with a rat’s brain, and progressing to a human brain, inside one of the world’s most powerful computers. The project hopes to bring into being a mind that will be able to think, reason, express will, lay down memories and perhaps even experience different emotions including love, anger, sadness, pain and joy.

Developers version 3.4.0.

Setting up the BlackBerry JDE Plug-in for Eclipse

To create a BlackBerry Application for a specific version of BlackBerry Device Software, you must use a version of

You can enable preprocessing for your applications by updating the Eclipse™ configuration file.
> In C:\Program Files\Eclipse\configuration\config.ini, add the following line:
osgi.framework.extensions=net.rim.eide.preprocessing.hook
If you enable preprocessing after you have had a build, you must clean the project from the Project menu before

osgi.framework.extensions=net.rim.eide.preprocessing.hook

Creating your own HelloWorld

Hope that you all are familiar with Eclipse

Click File -> New -> Project

In the window, drill down the blackberry and select blackberry project

give project name and click finish

In src folder, create a class HelloWorld under the package com.sample

orkspace… and then give your program a name like MyHelloWorld. In the second box add MyHelloWorld to the end of the creation path leaving off the last backslash. Click Ok and then Yes to the directory creation question. You now have a new workspace in which to put your project.

do similar for
HELLOWORLD_CONTENTSTRING
HELLOWORLD_EXITSTRING

Build and Run the Program..

Run As Blackberry Simulator
