我编写了一个函数,其目的是获取从重新缩放的输入图像定义的子图像的集合(这些子图像称为“重新缩放的输入图像的重新缩放的块”)并将这些重新缩放的块重新组装成输出整个图像(其尺寸是输入图像的那些,重新缩放)。所有块都具有相同的尺寸。
该函数定义如下。问题是 SonarLint 警告我认知复杂度是 16 而不是 15,而且我不想更改这个默认的 SonarLint 限制。我能做什么?
该功能的描述如下,代码如下:
final BufferedImage reassembleChunksInASingleImage(final int inputImageWidth, final int inputImageHeight, final int scalingCoefficient, final int chunkWidth, final int chunkHeight, final List<BufferedImage> theChunks) {
logger.log(Level.INFO, "Reassembling...");
final int reassembled_chunks_image_width = scalingCoefficient * inputImageWidth;
final int reassembledChunksImageHeight = scalingCoefficient * inputImageHeight;
final int rescaled_chunk_width = scalingCoefficient * chunkWidth;
final int rescaledChunkHeight = scalingCoefficient * chunkHeight;
final BufferedImage reassembledChunksImage = new BufferedImage(reassembled_chunks_image_width, reassembledChunksImageHeight, BufferedImage.TYPE_INT_RGB);
int indexOfTheChunkToUse = 0;
for(int i = 0; i < reassembled_chunks_image_width; i += rescaled_chunk_width) {
for(int j = 0; j < reassembledChunksImageHeight; j += rescaledChunkHeight) {
final BufferedImage chunkToUse = theChunks.get(indexOfTheChunkToUse);
int iForDraw = i;
int jForDraw = j;
final int deltaI = reassembled_chunks_image_width - (i + rescaled_chunk_width);
final int deltaJ = reassembledChunksImageHeight - (j + rescaledChunkHeight);
if(deltaI < 0) {
iForDraw -= Math.abs(deltaI);
}
我浏览重新缩放的图像,用块的足够(x 轴或 y 轴)尺寸(所有块具有相同的尺寸)增加水平或垂直移位。相关循环是:for(int i = 0; i < reassembled_chunks_image_width; i += rescaled_chunk_width) {for(int j = 0; j < reassembledChunksImageHeight; j += rescaledChunkHeight) {
我将当前重新缩放图像的像素颜色设置为当前块的颜色之一。相关循环是:for(int x = 0; x < rescaled_chunk_width; x++) {for(int y = 0; y < rescaledChunkHeight; y++) {
.
如果当前块超出了重新缩放图像的范围,我会将其移动到左侧或顶部,然后绘制它。相关控件是:if(deltaI < 0) {if(deltaJ < 0) {
.
