Question

我有一个项目来创建一个拼贴画，其中包含一些图像的副本，其中一些是翻转的，一些是颜色变化的等等。我对这一切都是全新的，并且几乎不知道我在做什么。我写了我的代码，但是当我在JES和命令探索（newpicture）中测试它时，弹出一个标题为“无”的白框。我试图弄乱它，但我被卡住了。在此之前我有我的所有defs用于翻转，改变颜色百分比等。我想我的问题是我测试不正确或者我的偏移或拼贴代码如下。为了测试我正在输入：

    verticalPicture = flipVertically(myPict)
    redPicture = matchRedToGreen(myPict)
    negativePicture = negative(myPict)
    bluePicture = clearBlue(myPict)
    clockwisePicture = rotateC90(myPict)
    newpicture = makeCollage(myPict)
    explore(newpicture)

def offsetPicture(littlePicture, bigPicture, xOffset, yOffset):
  for aPixel in getPixels(myPict):
  littleX = getX(aPixel)
  littleY = getY(aPixel)
  bigX = littleX + xOffset
  bigY = littleY + yOffset
  bigPicturePixel = getPixel (bigPicture, bigX, 375)
  setColor(bigPicturePixel, getColor (aPixel))

def makeCollage(myPict):
 newWidth = 3*getWidth(myPict)
 newHeight = 2*getHeight(myPict)
 bigPicture = makeEmptyPicture(newWidth, newHeight)
 offsetPicture(littlePicture, bigPicture, 0, 0)
 offsetPicture(clockwisePicture, bigPicture, getWidth(myPict), 0)
 offsetPicture(redPicture, bigPicture, 0, getHeight(myPict))
 offsetPicture(bluePicture, bigPicture, 2*getWidth(myPict), 0)
 offsetPicture(verticalPicture, bigPicture, getWidth(myPict), getHeight(myPict))
 offsetPicture(negativePicture, bigPicture, 2*getWidth(myPict), 2*getHeight(myPict))
return (bigPicture)

Answer 1

您的代码中存在一些缩进错误。我不知道这是否是将代码复制并粘贴到Stack Overflow中的结果。

发现错误：

return makeCollage()语句需要缩进一个空格。
offsetPicture()中for循环后的语句需要缩进。

您还可以在顶部找到以下代码行。这些行应该在您定义函数之后进行。

verticalPicture = flipVertically(myPict)
redPicture = matchRedToGreen(myPict)
negativePicture = negative(myPict)
bluePicture = clearBlue(myPict)
clockwisePicture = rotateC90(myPict)
newpicture = makeCollage(myPict)
explore(newpicture)
