只是想编辑一些代码,以便输出 jpg 质量不是默认的低质量设置
try
{
ImageIO.write(var6, "jpg", var7);
}
.....目前正在使用。
我看过一些其他设置质量的 Java 示例,但对 Java 不太熟悉,我无法理解如何插入内容并修改一些示例,这些示例是我在使用 Java 设置图像质量时看到的。
ImageWriteParam iwparam = new JPEGImageWriteParam(Locale.getDefault());
iwparam.setCompressionMode(ImageWriteParam.MODE_EXPLICIT);
iwparam.setCompressionQuality(quality);
writer.write(null, new IIOImage(image, null, null), iwparam);
这是我正在尝试工作的代码......

{
File var4 = new File(par0File, "screenshots");
var4.mkdir();

if (field_74293_b == null || field_74293_b.capacity() < var5)
{
field_74293_b = BufferUtils.createIntBuffer(var5);
field_74294_c = new int[var5];
