我目前正在使用处理草图来处理文件夹中的大量图像。我已经设置了onClick命令以前进到字符串中的下一个图像。这是非常耗时的,我想自动完成草图完成后的动作,草图将重复它自己从字符串中选择下一个图像。 onClick命令还将图像保存为导出文件夹,但每次使用相同的文件名保存时,我都尝试设置顺序编号,但到目前为止还没有工作。任何帮助将不胜感激。
String[] imgNames = {"1.jpg", "2.jpg", "3.jpg"};
PImage img;
int imgIndex = 0;
void nextImage() {
background(255);
frameRate(10000);
loop();
frameCount = 0;
img = loadImage(imgNames[imgIndex]);
img.loadPixels();
imgIndex += 1;
if (imgIndex >= imgNames.length) {
imgIndex = 0;
}
}
void paintStroke(float strokeLength, color strokeColor, int strokeThickness) {
float stepLength = strokeLength/4.0;
// Determines if the stroke is curved. A straight line is 0.
float tangent1 = 0;
float tangent2 = 0;
float odds = random(1.0);
if (odds < 0.7) {
tangent1 = random(-strokeLength, strokeLength);
tangent2 = random(-strokeLength, strokeLength);
}
// Draw a big stroke
noFill();
stroke(strokeColor);
strokeWeight(strokeThickness);
curve(tangent1, -stepLength*2, 0, -stepLength, 0, stepLength, tangent2, stepLength*2);
int z = 1;
// Draw stroke's details
for (int num = strokeThickness; num > 0; num --) {
float offset = random(-50, 25);
color newColor = color(red(strokeColor)+offset, green(strokeColor)+offset, blue(strokeColor)+offset, random(100, 255));
stroke(newColor);
strokeWeight((int)random(0, 3));
curve(tangent1, -stepLength*2, z-strokeThickness/2, -stepLength*random(0.9, 1.1), z-strokeThickness/2, stepLength*random(0.9, 1.1), tangent2, stepLength*2);

答案 0 :(得分:0)
你不能只从这个nextImage()
声明中调用if
函数吗?
if (frameCount > 10000) {
noLoop();
}
将是:
if (frameCount > 10000) {
nextImage();
}
至于使用不同的文件名,只需使用在保存文件时递增的int
,并在save()
函数中使用该值。或者您可以使用frameCount
变量:
save("img" + frameCount + ".tif");
如果您有后续问题,请发布MCVE而不是整个项目。尝试在一个只做一件事的小例子程序中一次隔离一个问题。祝你好运。
