Magnifying glass that follows cursor for canvas

由 99封情书 提交于 2021-02-07 14:23:56
问题 I'm working on a t-shirt designer for a client of mine and I made it using html5 canvas. The shirt designer is now finished but he requested I add a magnifying glass (something like this: http://mlens.musings.it/). I've found a lot of similar scripts out there, however, they all seem to have one thing in common they use a small and a large image. Using canvas, however, I have a different scenario and have been stumped on how I can add a magnifying glass to magnify where ever the cursor is on

问题 I'm searching for an image zoom solution for Angular 7, exactly like this I've found this, but it's for AngularJs. Is there something good as the linked example? 回答1: make a zoom it's only change the background with an image changing the background of a div according the move of the mouse, see, e.g. how create a image zoom in w3school background-image:... background-position:... background-size Imagine you has a component like: <div class="img-zoom-container"> <img #img id="myimage" [src]=

Change UISearchBar magnify icon color and position

由 ♀尐吖头ヾ 提交于 2020-01-04 06:15:21
问题 I have a UISearchBar and I would like to change the position of the initial magnify icon (the one that appears in the middle of the UISearchBar) as well as the color or icon. So far I changed the tint and the icon image. However, the new icon shows up only if I test the app on a simulator but on an actual device(both run iOS 9.3) it still shows the default icon. UISearchBar.appearance().setImage(UIImage(named: "SearchbarIcon"), forSearchBarIcon: UISearchBarIcon.Search, state: UIControlState

How to prevent the pixels from becoming blurry when I enlarge an image in my color pick project for iOS?

问题 I'm making a little project that provides the ability to enlarge an image and pick pixels' colors from the magnifier, now I can magnify the touched place of the image, but the magnifier shows the pixels with blurry effect, how can I make it show the pixels one by one very clearly without any fuzzy processing? - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGRect bounds = self.bounds; CGImageRef mask = [UIImage imageNamed: @"loupe-mask@2x.png"].CGImage;

Creating Magnifying Glass on website for text

由 旧巷老猫 提交于 2019-12-12 04:09:18
问题 I'm trying to find a HMTL code to create a magnifying glass that will magnify text on a website however I can only find codes for images. Could anyone help me out please? I'm not very code literate i'm afraid! 回答1: I think your best bet would be to use a CSS hover command for your text to scale up or down. (to keep things simple) Something like this: .grow:hover { transform: scale(1.1); } BUT If you are looking for a better explanation on the process, see @Andy 's answer to this question: How

Why do I see pixels when zooming WPF application in Windows?

由 五迷三道 提交于 2019-12-08 20:30:55
问题 I have developed a GUI for a random application using WPF. I have a bunch of out of box WPF controls laid on the application window. I haven't customized anything, didn't use bitmaps, etc. When running my application and zooming using Magnifier application in Windows 7 ( Win key + Plus key , the magnified GUI is showing pixels.I am probably wrong, because I can't explain it otherwise, but isn't WPF supposed to provide vector like control rendering? Thanks for participating in the discussion.

I have this : and what i want exactly is that to show portion of Bitmap via coords (X,Y) of object with OnTouchListener(orange square with dot in center). So the problem is that i want to draw portion of image like it shows on image(Red square " Area that i want " to show). So in this case,excepted result is(portion of bitmap) : At current moment i'm doing like this: public boolean onTouch(View view, MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_MOVE: Bitmap mBitmap = Bitmap.createBitmap(sourceBitmap,view.getX() - view.getWidth(),view.getY()-view.getHeight(),250,250

In iOS7 Text Magnifier isn't working app wide

I have a came across a rather annoying bug in one of my apps. In iOS7 when I hold down on a UITextView or UITextField to bring up the Magnifying Glass, nothing shows up in the magnified area. This problem is app wide and the only element that ever shows up in the circle area is the keyboard itself (when I drag my finger down to the top of it). I have tried everything from View Controllers with only a single UITextView to UIWebView and the problem is app wide. The magnifying glass works as expected on iOS6 devices, and the iOS7 simulator. But not on any of the devices I have tested it with
