使用c＃在插图框中插入位图中的线条 [英] drawing lines in a bitmap which is inserted in picturebox using c#

问题描述

我已经采用了一个表单，其中包含listbox和带有位图的图片框。
当我点击一个按钮时，
...执行一个名为createbitmapatruntime（）的动作;



当时位图是白色的，带有x和y轴......在鼠标移动时我们可以在放置的鼠标指针处找到坐标....



i有另一个按钮......当被触发时...用文件大小填充列表框（假设有20个文件）..
特定文件夹的
。



位图大小为800 * 600.



所有以MB为单位的文件大小都被转换到字节。



现在/...i想在x轴上为每次迭代绘制不同的文件大小。



假设origibnal文件大小为500 ...并且休息文件大小小于500 ...



x axiz将是10个部分...每个部分代表80分。



1ST文件coordiante（80,500）

第二档cordinate（160,480） ）...



第3个文件坐标（240,460）....依此类推......我应该如何标记点...然后画一条线或者使用这些点的曲线。

I have taken a form which consits of listbox and a picturebox witha bitmap.
when i click a button...an action is performed which is called createbitmapatruntime();

at that time the bitmap is white in colour with x and y axis...and on mouse move we can c the coordinates....at the placed mouse pointer.

i have another button...which when triggered...fills the listbox with filesizes(suppose 20 files)..
of a particular folder.

size of bit map is 800*600.

all the filessizes which are in MB is converted to bytes.

now /...i want to plot different file sizes for each iteration on x axis.

suppose origibnal file size is 500...and rest file sizes are less than 500...

x axiz will be 10 parts...each part representing 80 points.

1ST file coordiante(80,500)
2nd file cordinate(160,480)...

3rd file coordinate(240,460)....and so on...how should i mark points...and then draw a line or curve using these points.

推荐答案

你想绘制一个图形。

你可以自己写一个绘图库，最简单的方法是GDI +（查看图形 [ ^ ]类。但是，我建议不要使用这条路线并搜索CodeProject文章，用C＃绘制库。

You want to draw a graph.
You could write a plotting library yourself, the easiest way is probably GDI+ (look into the Graphics[^] class. However I would advice against this route and search CodeProject articles for plotting libraries in C#.
