QUESTION
I used the python module html2image to convert html to an image, but due to the fixed image size, the html is broken or cut off and there is a blank space. Is there any way to solve this problem using Python? (I use chat exporter to generate html code)

Answered 2021-May-24 at 19:01Here is one way to crop the non-transparent area using Python:
- Read the input image, and convert it to NumPy array.
The array has 4 color channels, the 4'th channel is alpha (transparency channel). - Find indices of non-transparent pixels - indices where alpha channel value is above zero.
- Get the minimum and maximum index in both axes (top left corner and bottom right corner).
- Crop the rectangle (and convert the cropped rectangle to an image).
- Save the cropped image (with RGBA color format).
Here is the code:

QUESTION
I want to create images from HTML. I found that website where they show how it can be done: codepedia.info
Yes, it works. But you have to press a “preview button” and afterward a “download link” to save the graphic. I want users to press only one button and download the graphic directly without the preview. Also other users asked for that and the webmaster explained that it's easily possible as follows:
All you need to copy both button code into one function and comment this line
$("#previewImage").append(canvas);
.

div before creating a new preview, so just use $("#previewImage").empty();
before invoking html2canvas
, or right after saving the image to disk.
