래스터 형식의 예외 (자바)

Question

나는 또 다른 질문을 볼 수 같은 일부 코드를 사용하려고 해요

대답 : https://stackoverflow.com/a/621849/1044984

이 사용되면 나는 다음과 같은 오류 얻을 : 여기

코드입니다 이 오류와 관련된 :

try { 

      tileSheetBig = ImageIO.read(new File("sprites/tiles.png")); 
      charSheetBig = ImageIO.read(new File("sprites/player.png")); 

     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

     final int tileWidth = 64; 
     final int tileHeight = 64; 
     final int tileRows = 1; 
     final int tileCols = 11; 
     tileSheet = new BufferedImage[tileRows * tileCols]; 

     for (int i = 0; i < tileRows; i++) { 
      for (int j = 0; j < tileCols; j++) { 
       tileSheet[(i * tileCols) + j] = tileSheetBig.getSubimage(i 
         * tileWidth, j * tileHeight, tileWidth, tileHeight);

     final int charWidth = 16;

     final int charRows = 2; 
     final int charCols = 3; 
     charSheet = new BufferedImage[charRows * charCols]; 

     for (int i = 0; i < charRows; i++) {

      } 
     } 

답변에 제공된 코드와 별다른 차이가 없으므로 문제가 무엇인지 알 수 없습니다. Google에 오류를 시도했지만 거기에는 많은 답변이 나와 있지 않습니다.

Answer 1

[X, Y, X + 폭, 높이 (Y) +]에 의해 지정된 영역이 때 RasterFormatExceptiongetSubImage() 의해 thrown 있다는 BufferedImage 지역 내에 포함되지 않는다.

tiles.png 이미지가 704x64 픽셀 (너비 * cols, 높이 * 행) 이상이고 player.png이 48x46 픽셀 이상인지 확인하십시오.

편집 : 죄송합니다. 언뜻보기에는 눈치 채지 못했습니다. player.png는 32x69 px 및 tiles.png이어야합니다. 64x704 px

EDIT 2 : 이렇게하면 스프라이트를 편집하지 않고 플레이어 코드가 수정됩니다. 타일에도 동일하게 적용하십시오.

final int charWidth = 64; 
final int charHeight = 64; 
final int charCols = 11; 
final int charRows = 1; 
for (int i = 0; i < charCols; i++) { 
    for (int j = 0; j < charRows; j++) { 
     charSheet[i * charRows + j] = charSheetBig 
      .getSubimage(i * charWidth, j * charHeight, charWidth, charHeight); 
    } 
}
