问题 Disclaimer: I rewrote most of this question, including its title, because I partially figured it out. I'd like to maximize the size of the button on all screen sizes, because it looks silly when it is to small. It should look similar to this: (Sadly, I cannot include a picture, because my reputation is too low.) But if I turn the orientation of the device, for example, the button matches it's parents width, becoming ugly proportioned. (Sadly, I cannot include a picture, because my reputation

Fitting ImageView Horizontally

耗尽温柔 提交于 2020-01-02 07:01:17
问题 I am developing a sort of ebook application and I am trying to display an image in the following two ways. When the screen is in portrait , I have the image horizontally fitted and vertically centered. When the screen is in landscape , I want the image to fill the screen horizontally with the aspect ratio maintained. Since the images that I am using are longer than they are wide, I have a ScrollView to allow viewing of the entire image. How should I be scaling my ImageView to achieve this? I

Can i use Calc inside Transform:Scale function in CSS?

问题 I'm trying to calculate the right scale to apply to children inside a parent but i can't use calc() inside transform: scale CSS function. I've done this function with javascript but i'm interested in a pure CSS solution to avoid bloating the page with scripts as much as possible. Example: CSS .anyclass{ height:250px; /*this value can change dinamically */ transform:scale(calc(100% / 490 )); /*is using height value*/ } This definition gives back an invalid property value. Other uses like

时光毁灭记忆、已成空白 提交于 2020-01-02 03:29:30
问题 Is there any way to make WPF application get same size at every system scale? When I change Change size of text, apps and other items in windows system setting from 125% (Recommended) to 100% in a Full-HD screen, My WPF application gets too small. To implement independent system scale application I've wrote a function like this to change scaling of my app back to 125%: private void ScaleTo125Percents() { // Change scale of window content MainContainer.LayoutTransform = new ScaleTransform(1.25

How to animate scale of TextBlock in UWP

问题 When I use Storyboard to zoom in TextBlock it pixelates while zooming and rerenders only on complete. <DoubleAnimationUsingKeyFrames Storyboard.TargetName="TextBlock" Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.ScaleY)"> <EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="1.5"/> Is there a way the TextBlock is rerendered each frame? 回答1: I found a solution though it's not about TextBlock anymore but for me it worked: private void CreateText(string text) { _compositor

matplotlib: Setting both major and minor ticks forces same x and y scale

∥☆過路亽.° 提交于 2020-01-01 18:13:51
问题 This question is related to the earlier question I asked "matplotlib: Change grid interval and specify tick labels" but now I want to change the scale for x and y axes. When I set the range for x and y axes and then specify the intervals for major and minor ticks, it forces the x and y axes to be the same. This is my code. import matplotlib.pyplot as plt import numpy as np fig = plt.figure() ax = fig.add_subplot(111) for key, value in sorted(data.items()): x = value[0][2] y = value[0][3]

问题 i don't want to use the scale as classic zoom, instead i want to change the form of quadrates to a rectangle for example. After a lot of trying i'm that far that my fingers are the corners of the rectangle. So but if i start a new pinch gesture inside my view gets smaller to my fingers instead of getting bigger like the normal scale does. if ([gestureRecognizer numberOfTouches] >1) { //getting width and height between gestureCenter and one of my finger float x = [gestureRecognizer

Opencv multiply scalar and matrix

问题 I have been trying to achieve something which should pretty trivial and is trivial in Matlab . I want to simply achieve something such as: cv::Mat sample = [4 5 6; 4 2 5; 1 4 2]; sample = 5*sample; After which sample should just be: [20 24 30; 20 10 25; 5 20 10] I have tried scaleAdd , Mul , Multiply and neither allow a scalar multiplier and require a matrix of the same "size and type". In this scenario I could create a Matrix of Ones and then use the scale parameter but that seems so very
