Determine if an image file is a photo or a graphic?

由 牧云@^-^@ 提交于 2019-12-12 08:04:23
问题 I'm embarking on what I believe may be somewhat of an experiment... To come up with (or discover, as it could already exist) a method to determine whether a given image file, regardless of format, is a photo or a graphic. "Photo" meaning something like scenery, people, etc. V.S. "Graphic" meaning an icon, illustration, chart, UI screenshot, etc. I came up with a nice PHP / ImageMagick script in the past week which pulls statistics from image files and nicely applies fixes to white balance,

Java Swing show progress in pie form

由 主宰稳场 提交于 2019-12-12 07:22:49
问题 I want to show a progress in pie format. Can anyone help? I have the data to show, but how to show it in this format. Something like progress shown in Google Chrome when we download files. 回答1: Based on the links provided by @trashgod, here is one way you can achieve a "Pie" effect. This only handles the indeterminate progress bar, but it would be very easy to add the "determinate" behaviour. import java.awt.BorderLayout; import java.awt.Color; import java.awt.Dimension; import java.awt

Does Java have any known issues with Images and displaying them

由 懵懂的女人 提交于 2019-12-12 05:27:58
问题 I am new to Java but not new to graphics I'm trying to expand my understanding with a project in which I'm displaying many photos of items using JLabels and Icons to display them, The items pictures are garnished from various locations on the net and so many sources. I've converted these into PNG files as they have transparent backgrounds to them. Thing is I wasted a whole weekend recently checking and re-checking some code because one item just would not display, following the logic to its

Print hierarchical vertices in a graph [closed]

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed last year . How to print all the parents of a given node. 回答1: Graham's answer is okay, but uses expensive path computations, which are not really required for your use-case. This is how I've set up your graph: g = TinkerGraph.open().traversal() g.addV().property(id, 1).as("v1"). addV()

DrawEllipse: Antialiasing broken with PenAlignment.Inset

由 耗尽温柔 提交于 2019-12-11 20:13:00
问题 As suggested by @TaW on this previous question, I setted PenAlignment.Inset to draw the circle inside the Bitmap, but this caused another problem. I want to draw a circle on a specified Bitmap with antialiasing. SmoothingMode.AntiAlias The problem is that, when I use PenAlignment.Inset , the antialiasing doesn't work correctly! Instead, with PenAlignment.Center , it works correctly... Any suggestion to resolve this problem? Bitmap layer = new Bitmap(80, 80); using (Graphics g = Graphics

How to Optimize this Image convolution filter Method in MonoTouch?

由 旧时模样 提交于 2019-12-08 07:37:37
问题 After having realized that no realtime graphics effect library exists for MonoTouch, I decided to write my own. After some research I've written a convolution method that works perfectly but, even using unsafe code, is VERY SLOW. What I'm doing wrong? Is there some optimization that I'm missing? Here is my c# class, any suggestion, not matter how small, is welcome! using System; using System.Drawing; using MonoTouch.CoreGraphics; using System.Runtime.InteropServices; using MonoTouch.UIKit;

How can I make my n-resize display correctly?

由 此生再无相见时 提交于 2019-12-04 18:13:02
Here is modified code originally tooken from this post . Resizing the rectangle on the Right middle, bottom middle and right bottom control point is fine as I don't need to change the translate coordinates in order to make the resize work. Now my problem as you can see is that my resizing on the top middle (same for the left middle, left bottom...) of my rectangle when the rotate angle is different from 0 doesn't work as it visually changes position when I resize it. I really don't know how to change that so any help is highly appreciated. note: change angle to 0 in the input field and you'll
