BY CRAIG CHAPMAN · PUBLISHED 2015-08-05 · UPDATED 2015-08-20   I have a customer with an application which makes heavy use of GDI calls for graphics rendering, and with a desire to migrate this application to OSX. Unfortunately, in this case, OSX has…
在.net下,如果你加载了一副8位的灰度图像,然后想向其中绘制一些线条.或者填充一些矩形.椭圆等,都需要通过Grahpics.FromImage创建Grahphics对象,而此时会出现:无法从带有索引像素格式的图像创建graphics对象 这个错误,让我们的后续工作无法完成.本文叙述了一种另外的方法来实现它. 我们通过Reflector发编译.net framework的相关函数后发现,FromImage的实现过程如下: public static Graphics FromImage(Imag…

问题场景:asp.net给图片添加文字水印保存为jpg格式时出现标题所描述错误(图片为.jpg格式): 简单验证:用本机的画图程序打开,然后保存为jpg格式会出现警告框"画图程序不能存储该文件,保存被中断  所以文件未被保存"     解决代码:              try             {                 using (System.Drawing.Image image = System.Drawing.Image.FromFile(@"D…
大家在用 .NET 做图片水印功能的时候, 很可能会遇到 “无法从带有索引像素格式的图像创建graphics对象”这个错误,对应的英文错误提示是“A Graphics object cannot be created from an image that has an indexed pixel format" 这个exception是出现在 System.Drawing.Graphics g = System.Drawing.Graphics.FromImage("图片路径"…

最近在尝试Direct2D编程,挺好玩的. 但是有时候还是会用到GDI+来生成图片,但D2D绘图需要用到自己的D2DBitmap类. 因此需要转换,查阅了下网上的资料,写了这么一个方法: using System; using System.Windows.Forms; using System.Linq; using System.Text; using System.Diagnostics; using DX = SharpDX; using D2D = SharpDX.Direct2D1;…
Graphics类(纸) Graphics类封装一个GDI+绘图图面,提供将对象绘制到显示设备的方法,Graphics与特定的设备上下文关联. 画图方法都被包括在Graphics类中,在画任何对象时,我们首先要创建一个Graphics类实例,这个实例相当于建立了一块画布,有了画布才可以用各种画图方法进行绘图.   现实中作画或写字,都离不开笔(Pen).墨(Brush).纸(Graphics).砚,那么今天说的Graphics类就相当于纸. 绘图程序的设计过程一般分为两个步骤: 创建Graphi…
