有可能利用《条约汇编》产生一份PDF文件,其中载有150份复印件的成像。
(图象是,它正在将图像质量降低到72pi。)

见thread 。 http://itext-general.2136553.n4.nabble.com/Image-units-of-measurement-td2140117.html。 阅读得很好。
Essentially (and this isn t technically accurate but close enough) by default, when you place an image using iText assume for every 72 pixels that 1 inch of printed space will be used. If you want to change this rule then you need to change the image s matrix
. You can either do this directly (which is hard) or use the scaling methods (much easier) such as scaleAbsolute()
, scaleAbsoluteWidth()
, scaleAbsoluteHeight()
, scalePercentage()
and
scaleToFit()
.
改变“<><>>
所有这些都可能给你的头部造成伤害,特别是如果你重新利用Adobe照片店等节目,允许你为某些图像类型制定“解决方案”。 不幸的是,这更多是“印有线”的,实际上并没有改变如此之多的档案。 72DPI的100x100帕克斯图像与300DPI的100x100 pixel完全相同,但印刷除外。 i Text完全忽视了这一印刷线,要么是因为所有印刷形式都支持它。 (没有直接关联,但一个共同的神话是,“网络之声”在现实中将第72DPI号决议的信息完全从档案中删除时,就使图像变得如此。)
忽视实际发生的情况,使图像成为你认为的150个新闻部的形象,将来源图像的阴 w和高高压带和多面带带在<00.48(72除以150外)上,并将这些新数字传送到plAbsolute(
)。
在<代码>Image类别中有一种称为setDPI
的方法,但只要我能告诉它,实际上不会对图像的放置有任何影响,而且更是信息。
