在没有文本的情况下调整照片大小..是否需要 RenderingHints？
我正在编写一个快速的小java类，它将图像大小调整为各种较小的尺寸（缩略图大/小/等）。我见过其中包含 RenderingHints 的示例。输出文件比没有时大得多。
我的问题是：如果正在调整大小的图像没有文本，是否有必要使用 RenderingHints？
int IMG_WIDTH = 100;
int IMG_HEIGHT = 100;
BufferedImage resizedImage = new BufferedImage(IMG_WIDTH, IMG_HEIGHT, type);
Graphics2D g = resizedImage.createGraphics();
g.drawImage(originalImage, 0, 0, IMG_WIDTH, IMG_HEIGHT, null);
g.dispose();
g.setComposite(AlphaComposite.Src);
g.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
我从 45kb 图像开始，输出差异是 3kb 文件（不带 RenderingHints）与 24kb 文件（带 RenderingHints）
I am writing a quick little java class that resizes an image into various smaller sizes (thumbnail large/small/etc). I have seen examples that have RenderingHints in it. The output file is significantly larger than without.
My question is: Is it necessary to use RenderingHints if the images that are being resized have no text?
int IMG_WIDTH = 100;
int IMG_HEIGHT = 100;
BufferedImage resizedImage = new BufferedImage(IMG_WIDTH, IMG_HEIGHT, type);
Graphics2D g = resizedImage.createGraphics();
g.drawImage(originalImage, 0, 0, IMG_WIDTH, IMG_HEIGHT, null);
g.dispose();
g.setComposite(AlphaComposite.Src);
g.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
I started with a 45kb image, and the output difference is a 3kb file (without RenderingHints) versus a 24kb file (with RenderingHints)

我想，在阅读以下 stackoverflow.com 问题/答案后：
我是倾向于认为当照片不包含文本时 RenderingHints 不会为我提供任何好处...在这种情况下，没有文本 = 没有 RenderingHints = 较小的调整大小图像
I suppose, after reading the following stackoverflow.com question/answer:
I am inclined to think that RenderingHints will provide no benefit for me when the photos contain no text ... In which case, no text = no RenderingHints = smaller resized image
