Automate Meme Creation with Python: Image Overlay and Text Styling

Material Preparation

We start with the widely used "Jin Guan Zhang" meme, place a cute panda head as the background, and add text to form a meme image.

Resize the image to a 250×250 template and trim white borders.

Image Overlay

The first step is to paste the meme face onto the template, taking care that the face image has a white background rather than transparency.

<ol><li><code>from PIL import Image, ImageDraw, ImageFont</code></li><li><code>img = Image.open(".ackground.jpg")</code></li><li><code>jgz = Image.open(".jgz.jpg")</code></li><li><code>img.paste(jgz,(73,42))</code></li><li><code>img.show()</code></li></ol>

The combined image is displayed:

Text Overlay

Although the meme’s core is the image, a short, striking caption often adds the final punch.

<ol><li><code>draw = ImageDraw.Draw(img)</code></li><li><code>ttfront = ImageFont.truetype('simhei.ttf', 24)</code></li><li><code>draw.text((32,190), "我的内心毫无波动   甚至还想笑", fill=(0,0,0), font=ttfront)</code></li><li><code>img.show()</code></li><li><code>img.save('.Python生成的表情包.jpg')</code></li></ol>

The final meme image with caption is generated:

The draw.text() function can be called repeatedly to add multiple text layers, enabling batch production of memes.

Problem Elevation

Consider the challenge of fitting a caption that mixes Chinese, English, and many punctuation marks into the limited blank space below the meme:

Space for the caption is limited.

Chinese characters, English letters, and punctuation occupy different widths.

If the text is too long, it must wrap; too many lines may exceed the image height.

Design an algorithm to determine appropriate font size, insertion position, and line‑break points so that the mixed‑language caption is centered and visually appealing within the constrained area.

Through this tutorial we learned a practical Python technique for simple image processing and automated meme generation.
