Image Processing in BAS

When a bot needs to produce or inspect pictures — stamp a watermark, build a content image, compare two pictures, or work an image captcha — the Image Processing module is the tool. It edits images you load and searches for pictures within pictures.

What it’s for

The module exists to edit and process images you load in your tasks. The two headline use cases:

• Content generation — say you build an auto-posting bot for Telegram and need to overlay a watermark, text or description onto a picture before publishing. This module does it.
• Captchas and comparison — it’s frequently needed to help solve captchas, where comparing one image with another is the core operation.

The actions

Lifecycle.

• Start / finish working with an image — open an image to operate on, then release it.
• Create an empty image — start a blank canvas.
• Change image format — convert between formats.

Editing and compositing.

• Change size — resize.
• Overlay text — stamp text onto the image (watermarks, captions).
• Insert one image into another — composite images together.
• Fill with primary colour — paint a background.
• Get part of an image — crop a region.

Inspecting and matching.

• Get image data — read the raw data.
• Get pixel colour — read a single pixel, useful for checks and captcha logic.
• Search for one image inside another — locate a template within a larger image, the basis of image comparison and many captcha solves.

Where it fits

Image processing usually serves a bigger scenario rather than standing alone: it’s the watermarking step inside a content generator, the comparison step inside a captcha solver, the resize step before an upload. Combined with the string and file modules, it lets a bot generate finished media end to end — fetch a base image, overlay text, save, and post.
