Implement lens magnification to magnify the Windows Taskbar

由 谁说我不能喝 提交于 2021-02-11 15:19:13
问题 I want to be able to perform lens magnificaiton on top of the windows taskbar. So far I've been unsuccessful in implementing this seeing as the taskbar will always open on top of my window. Windows built-in magnifier is able to do this so I'm hoping it is indeed possible. I've attached two screenshots showing Windows built-in magnifier and how it is able to magnify the taskbar and how my application will render below the taskbar. Windows built-in Magnifier: My application: Is there any way to

How to achieve magnifying square effect for D3 charts?

问题 Take a look at this jsfiddle. Magnifying on hover works well for text and images, but I would like to have the same effect for the chart. I would like the solution, if possible, to be applicable to any D3 SVG-based chart. The example uses jquery plugin AnythingZoomer, it looked to me as a good starting point, however, you don't need to stick to it, you can use anything else if you wish. I am aware of D3 fisheye pluging, this is related, but not quite what I want. 回答1: You can do this by not

Figure Size & Position after Matplotlib Zoom

由 北城余情 提交于 2019-12-24 00:58:14
问题 I have a matplotlib image plot within a wxPython panel that I zoom in on using the native matplotlib toolbar zoom. Having zoomed in I wish to know the size of the resulting image so that I can calculate the magnification. Moreover, I wish to know the position/dimensions of my zoomed in image in relation to the original image so that I can re-plot it again at a later time. I don't know how to approach this. I have looked over documentation for canvas and figure but haven't found anything which

How to add a magnifier to custom control?

How to add a magnifier to custom control? Control is a child of UIView. (It's a UIWebView - but native magnification functionality doesn't work at some pages.) UPDATED: Maybe it's possible to force a draw of magnifier on UIWebView? 1. Add the following files to your project: MagnifierView.h: // // MagnifierView.h // SimplerMaskTest // #import <UIKit/UIKit.h> @interface MagnifierView : UIView { UIView *viewToMagnify; CGPoint touchPoint; } @property (nonatomic, retain) UIView *viewToMagnify; @property (assign) CGPoint touchPoint; @end MagnifierView.m: // // MagnifierView.m // SimplerMaskTest //

How to disable the magnifying glass in UIWebview?

问题 How can I disable the magnifying glass that appears when you hold the touch on a UIWebView? I don't want to to disable user interaction but I don't want the webview to show that zoom glass. Any Ideas? 回答1: No, the loupe is inextricably linked to selection. To disable it, you will have to disable selection entirely (you can use -webkit-user-select: none to do that). 回答2: Because the accepted solution did not work for me, I had to look for other options and I found one. Note that I don't know
