I'm using Paint blackThin = new Paint (); blackThin . setStrokeWidth ( 0.1f ); blackThin . setColor ( Color . BLACK ); to initialize the paint object. This works fine in Android 2.2, but when I try it in 4.2 (also 4.1, I think - I tested that one briefly - I haven't tested any other versions other that 2.2, 4.1.2 and 4.2) the lines won't show up when I draw them. To make them show up in 4.2, it seems like I have to set the anti-aliasing flag to be true. (I

What is Device Pixel Ratio for?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: As far as I know it's the ratio between the "abstract" resolution and the device's physical resolution. So I test it (on HTC Desire), the physical resolution is 480x800 , it's logged out the ratio is 1.5 . I threw in some elements, but it still take exactly 480px width to fill the viewport where my naive thought it's need '320px'? 回答1: From http://www.quirksmode.org/blog/archives/2012/07/more_about_devi.html , where the author discusses the differences in devicePixelRatio across mobile devices: On iOS Retina devices, screen.width gives the

How does invisible pixel conversion tracking work?

≯℡__Kan透↙ 提交于 2019-12-03 00:33:40
问题 I'm trying to track clicks from our site to an external website. On the external website, I'd like to place some code on their checkout thank-you page, that tells our server that a particular click has resulted in a sale. How does this tracking code work? Does it need to be a pixel? Do we need to drop a cookie before we send the user to the external website? Thanks. 回答1: Pixel-based conversion tracking is pretty straightforward. You set up a basic web server to accept HTTP GET requests and

《Ray Tracing From The Ground Up》Chapter3

Bare-Bones Ray Tracing 这一章内容是写一个最简单的光线追踪器,我们trace plane 和 sphere 就可以了。 本篇文章主要是整理代码结构,具体图形学知识一定要看书,书上讲的很清楚。 本章的光线为平行光,起点都在viewplane,方向为z轴负方向。我们把要trace的物体放在viewplane后面。显示被光线击中并且离viewplane最近的物体的颜色。 本书作者给的代码实现中包含了很多类,所以理解起来有点困难。并且因为作者给的代码不能直接运行(编译会报错),我重新按照作者的结构实现了一下,不过去掉了Point3D这个类,所有三维的点都用Vector3D表示。输出的图像为PPM格式,代码运行环境为Archlinux,没在windows环境下测试过。 在此整理一下我的代码结构: 首先看下有main的主代码: #include "World.h" #include <fstream> #include <iostream> using namespace std; ofstream out; int main() { out.open("fileppm.ppm", ios::out); out << "P3\n" << 400 << " " << 400 << "\n255\n"; World w; w.build(); w.render_scene()

本文中,首先会介绍模型保存与加载的过程与要点,然后通过一个实例完成VGG模型数据的探索与加载的小demo。 通过本文,可以学到如何用Tensorflow保存和加载模型。 模型保存通过 tf.train.Saver() 对象实现。 def save () : """ 模型保存 :return: """ # 创建两个随机tensor v1 = tf.Variable(tf.random_normal([ 2 , 2 ]),dtype=tf.float32,name= 'v1' ) v2 = tf.Variable(tf.random_normal([ 3 , 3 ]),dtype=tf.float32,name= 'v2' ) init = tf.global_variables_initializer() # session执行init,然后查看变量值,之后保存 with tf.Session() as sess: sess.run(init) print( 'v1:' ,v1.eval()) print( 'v2:' ,v2.eval()) # 保存结果 saver = tf.train.Saver() # 这里后缀名ckpt,表示checkpoint,这个可以任意 save_path = saver.save(sess, 'model/test.ckpt' ) print(
