uiimageview

I have it where a user can move an image and uilabel around the screen. Say it is a black image and black text. I want the portion of the text that overlaps with the image to become transparent so that the background shows through and you can still read the text even though they were originally the same color. Hopefully this makes sense. I've found some links on erasing with touch. I'm not sure how to go about automating this with the portion of the text that overlaps. Maybe something like this "Masking an image with an image"? https://developer.apple.com/library/mac/#documentation

I am attempting to save and load a UIImage to and from the iPhone documents directory after the image is picked from the iPhone Photo Library. It is able to do so, but for some reason, when I load the image, it rotates it 90 degrees counterclockwise. Here is my saveImage and loadImage methods: Save Image: - (void)saveImage: (UIImage*)image{ if (image != nil) { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString* path = [documentsDirectory stringByAppendingPathComponent: [NSString

I am using tesseract open source engine for OCR to read text from image. But I didn't get 100% result for a single time. Please give your suggestions about quality improvement for OCR using tesseract. Thanks here is how to get best result from tesseract Please make sure that you have done preprocessing on image. OVR will produce best results for the images which have following properties: fix DPI (if needed) 300 DPI is minimum fix text size (e.g. 12 pt should be ok) try to fix text lines (deskew and dewarp text) try to fix illumination of image (e.g. no dark part of image binarize and de-noise

I have an ImageView when clicked on that imageview, transparent circle should be created and again when double clicking on that circle, particular Image in that circle area should be zoomed.Any suggestion would be appreciated. sandy I think this code will helpfull to you - (id)initWithImage:(UIImage *)image { self = [super initWithImage:image]; if (self) { [self setUserInteractionEnabled:YES]; UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)]; UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc]

Just did this: self.imageView.backgroundColor = color1; self.imageView.layer.masksToBounds = YES; self.imageView.layer.borderColor = color1; self.imageView.layer.borderWidth = 3.0; Here is screenshot of the problem: I can see image, borders, and image fragments out of the border… How can I fix it? I had a similar issue using the border properties on the layer and managed to solve it by adding a CAShapeLayer on top. I can't tell you how it will behave on older devices as haven't tested it with many animations and so on, but I really doubt it will slow them down. Here is some code in Swift:

My problem is as follows: I have on top of a UIImageView some labels. The image is a formular and the UILabel s represents the entries. If I rotate the device the image inside UIImageView gets resized with option "aspect fit". How can I achieve that the UILabel is also resized and aligned correct? The normal options for resizing aren't working as needed. The UIImageView is zoomable with minimumZoomScale and maximumZoomScale set. Thanks. You can resize a UILabel proportionally using: label.transform = CGAffineTransformMakeScale(0.5, 0.5); You can reposition a UILabel relatively using: label

I have a UIImagePickerController that saves the image to disk as a png. When I try to load the PNG and set a UIImageView's imageView.image to the file, it is not displaying. Here is my code: - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; NSData *imageData = UIImagePNGRepresentation(image); // Create a file name for the image NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setTimeStyle:NSDateFormatterShortStyle];

i'm looking to remove an image from my app with a curl up animation. I've got [UIView transitionWithView:sender.view.superview duration:1.5 options:UIViewAnimationOptionTransitionCurlUp animations:^ { [sender.view removeFromSuperview]; } completion:nil]; but this curls the entire page away and looks as though there's a separate page beneath without the image on it. Instead of a 'transition' to a new page is it possible to curl the image off the page without affecting the rest of the page? Do I need to wrap the imageview in a 'container view' and change transition with view to that? Your view
