wkhtmltopdf +混合照片颜色 [英] wkhtmltopdf + mixed photo colors
问题描述
我有一个颜色和黑色&的页面白色图像,当我使用wkhtmltopdf从html文件生成pdf时,
I have a page with color and black & white images, when I use wkhtmltopdf to generate a pdf from the html file,
我只得到彩色图像,如何让它打印所有图像,我已经尝试过预选项,但没有成功。
I get only the color images, how can I get it to print all the images, I have tried the advance options, but no success.
如果我以灰度打印,那么所有图像都会出现,但我不想要灰度。
If I print in grayscale, then all the images are coming, but I don't want grayscale.
任何帮助?
推荐答案
我想出了如何解决这个问题,我试过了一个试错法,并且发现如果我们提供以下参数所有图像,无论颜色或B& W,它都会出现
I figured out how to solve this problem, I tried a trial-and-error method and figured out that if we provided the following parameters all the images irrespective of color or B&W, it would come up
wkhtmltopdf - 图像质量75
wkhtmltopdf --image-quality 75
注意:任何值< = 75都有效,较高的值仅为B& W图像打印空白
NOTE: Any value <= 75 works, higher value print a blank space for B&W images only
