dpi

问题 I've learn how to manage different DPI settings the hard way, so that at runtime my applications are properly displayed. But there is still a big issue with Design time Visual Studio. Say I build an application at 96 dpi and I switch my display to 120 dpi for testing purposes. Now IF I open a form designer at 120 dpi, the form is resized according to 125%, the controls moved aso! :-((( So I try to avoid reopening forms, but that's NOT a nice solution, isn't it? Is there by any chance a design

问题 Google suggests to create for each image 4 different versions - one for each density (ldpi, mdpi, hdpi, xhdpi). Sometimes you might even want to create others, based on the screen size (small, normal, large, xlarge). This causes a weird situation where most of the app's images will never be used by the app, right? How come Google doesn't create multiple APKs on their website, to target the best APK to the end user's device, so that 100% of the resources will be targeted on the device's specs?

问题 I have created a new Bitmap object and now want do draw some text to it using GDI+. So I call Graphics.DrawString(...). The problem is that the size of the string depends on Windows 7's DPI settings. Is there any way to make my text drawing independent of the windows settings? PS: The DPI settings seem to affect text only. A rect for example stys the same size when changing the DPI... 回答1: Just found the solution myself: The key is to create the font with the parameter GraphicsUnit.Pixel.

问题 How do Dpi Points relate to Pixels for any display my application is running on? int points; Screen primary; public Form1() { InitializeComponent(); points = -1; primary = null; } void OnPaint(object sender, PaintEventArgs e) { if (points < 0) { points = (int)(e.Graphics.DpiX / 72.0F); // There are 72 points per inch } if (primary == null) { primary = Screen.PrimaryScreen; Console.WriteLine(primary.WorkingArea.Height); Console.WriteLine(primary.WorkingArea.Width); Console.WriteLine(primary

问题 In the past I had seen occasions where images that weren't 72 dpi wouldn't show in some web browsers, primarily Internet Explorer 7. However, weird thing is, I have tested this lately and it appears that images of 300dpi are showing in IE. Does DPI matter anymore for web? Will photos of some DPIs not display in some web browers? 回答1: No, it doesn't and it never matter. DPI only matters for printing. 来源： https://stackoverflow.com/questions/3803644/does-image-dpi-matter-to-web-browsers

问题 I am trying to create images programatically on Python using Pillow library but I'm having problems with the image quality of the text inside the image. I want to save the Image the I generate to PNG, so I'm setting the DPI when saving according to this, but whether I save with dpi=(72,72) or dpi=(600,600) it visually looks the same. My code for doing it is the following: from PIL import Image, ImageDraw, ImageFont def generate_empty_canvas(width, height, color='white'): size = (width, height

问题 Note: this question may not be suitable to SO, but I'd like to ask here because I want to hear from Mac OS X developers. Macbook Pro Retina (MPB Retina) has a native 2880x1800 resolution. However, such native resolution is not directly exposed. Rather, resolutions like 1440x900 and 1920x1200 are provied as shown in the below figure. I want to know what resolution programmers will see . Is it 2880x1800? Or, a reduced resolution? I'm particularly interested in how Mac OS X handles such ultra

问题 I'm facing a issue which related to dpi setting of windows. If the windows dpi setting is set to 100% everything is fine. But if user changed it to 125%...some part of my application displayed a wrong size. I know the problem and I know how to deal with but my customer wants that when application running, if the current dpi setting of windows is not equal to 100% -> change it to 100% And I'm standing still with the solution. Do you have some solution to change windows dpi setting value?
