怎么用java代碼模擬一張圖片

用java代碼模擬一張圖片可以這樣操作：1.創(chuàng)建BufferedImage類

2.根據(jù)BufferedImage類得到一個(gè)Graphics2D對(duì)象

3.根據(jù)Graphics2D對(duì)象進(jìn)行邏輯操作

4.處理繪圖

5.將繪制好的圖片寫(xiě)入到圖片

解析下這個(gè)生成圖片的Java代碼

1.調(diào)用"images"文件夾里的文件放在ImageIcon里顯示2.在windows下面顯示正常Java在圖形處理時(shí)調(diào)用了本地的圖形處理庫(kù)。在利用Java作圖形處理（比如：圖片縮放，圖片簽名，生成報(bào)表）時(shí)，如果運(yùn)行在windows上不會(huì)出問(wèn)題。如果將程序移植到Linux/Unix上的時(shí)候有可能出現(xiàn)圖形不能顯示的錯(cuò)誤。3.提示信息："Can'tconnecttoX11windowserver"這是由于Linux的圖形處理需要一個(gè)XServer服務(wù)器。（關(guān)于Linux的圖形處理模式參考Tomcat的修改如下：打開(kāi)%Tomcat_home%/bin/catalina.sh文件在文件的86%處，啟動(dòng)Tomcat的腳本中加上:-Djava.awt.headless=true/參考："$_RUNJAVA"$JAVA_OPTS$CATALINA_OPTS/-Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS"-classpath"$CLASSPATH"/-Dcatalina.base="$CATALINA_BASE"/-Dcatalina.home="$CATALINA_HOME"/-Djava.io.tmpdir="$CATALINA_TMPDIR"/-Djava.awt.headless=true/org.apache.catalina.startup.Bootstrap"$@"start/"$CATALINA_BASE"/logs/catalina.out21if[!-z"$CATALINA_PID"];thenecho$!$CATALINA_PIDfifielif["$1"="stop"];then保存后，重新啟動(dòng)就可以處理圖形了。
