本文实例讲述了python通过pil为png图片填充上背景颜色的方法。分享给大家供大家参考。具体分析如下:
png图片有些是没有背景颜色,如果希望以单色(比如白色)填充背景,可以使用下面的代码,这段代码将当前目录下的 jb51.net.png图片填充了白色背景。
使用指定的颜色的背景色即可,然后把该图片用alpha通道填充到该单色背景上。
比如下面使用白色背景:
im = Image.open('jb51.net.png') x,y = im.size try: # 使用白色来填充背景 from:www.jb51.net # (alpha band as paste mask). p = Image.new('RGBA', im.size, (255,255,255)) p.paste(im, (0, 0, x, y), im) p.save('jb51.net.png') except: pass
希望本文所述对大家的Python程序设计有所帮助。

You can manage different Python versions by using pyenv, venv and Anaconda. 1) Use pyenv to manage multiple Python versions: install pyenv, set global and local versions. 2) Use venv to create a virtual environment to isolate project dependencies. 3) Use Anaconda to manage Python versions in your data science project. 4) Keep the system Python for system-level tasks. Through these tools and strategies, you can effectively manage different versions of Python to ensure the smooth running of the project.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
