通过拉动进度条的位置(1到99),可以改变JPG/PDF品质设置,此设置项目只影响扫描输出格式为JPG或PDF的效果,不影响实时图像和预览效果.
该选项设置JPG图像的压缩率,品质越高(该数值越大),图像品质越好,则压缩率越小,即保持的JPG或PDF文件更大;反之,品质越低(该数值越小),图像品质越差,则压缩率越高,即保持的JPG或PDF文件更小.建议选用在70-90之间,一般选择为75既可以达到良好的图像效果,并具有比较小的文件(通常全范围扫描在300K左右).
By pulling the progress bar's position (1 to 99) that can change JPG/PDF quality setting,this setting only affects the scan output format is JPG or PDF,does not affect live images and preview the results.
This option sets the JPG image compression,the higher the quality (the higher the value),the better the image quality,the smaller the compression rate,that maintains the JPG or PDF file larger; Conversely,the lower the quality (the smaller the number,),the lower the image quality,the higher the compression ratio,i.e.keep the JPG or PDF file smaller.It is proposed to adopt in 70-90,in General,choose between 75 can achieve good image effects,and has a smaller file (usually full range scan around the 300K).
