Python Qt6 : tool for game development with PNG images.

Today, I worked with art artificial intelligence, to create tool for my game development.

I used python and PyQt6 and this tool help me to remove border, resize, split, rename and save images as PNG file type for Godot game engine.

Python 3.10.7 : Krita and python - part 002.

A simple source code to export PNG file for Godot game engine as Texture2D .

from krita import *
from PyQt5.QtWidgets import QAction, QMessageBox
import os

class ExportGodotPNG(Extension):
    def __init__(self, parent):
        super().__init__(parent)

    def setup(self):
        pass

    def export_png(self):
        # Get the active document
        doc = Krita.instance().activeDocument()
        if not doc:
            QMessageBox.warning(None, "Error", "No document open! Please open a document and try again.")
            return

        # Create an InfoObject for PNG export
        info = InfoObject()
        info.setProperty("alpha", True)  # Keep alpha channel for transparency
        info.setProperty("compression", 0)  # No compression for maximum quality
        info.setProperty("interlaced", False)  # Disable interlacing
        info.setProperty("forceSRGB", True)  # Force sRGB for Godot compatibility

        # Build the output file path
        if doc.fileName():
            base_path = os.path.splitext(doc.fileName())[0]
        else:
            base_path = os.path.join(os.path.expanduser("~"), "export_godot")
        output_file = base_path + "_godot.png"

        # Export the document as PNG
        try:
            doc.exportImage(output_file, info)
            # Show success message with brief usage info
            QMessageBox.information(None, "Success", 
                f"Successfully exported as PNG for Godot: {output_file}\n\n"
                "This PNG has no compression, alpha channel support, and sRGB for Godot compatibility. "
                "To use in Godot, import the PNG and adjust texture settings as needed."
            )
        except Exception as e:
            QMessageBox.critical(None, "Error", f"Export failed: {str(e)}")

    def createActions(self, window):
        # Create only the export action in Tools > Scripts
        action_export = window.createAction("export_godot_png", "Export Godot PNG", "tools/scripts")
        action_export.triggered.connect(self.export_png)

# Register the plugin
Krita.instance().addExtension(ExportGodotPNG(Krita.instance()))

Python 3.13.0 : Script for python modules then installs them - updated with fix.

This script scans a folder full of .py files Python scripts, identifies all the external modules they import, filters out built-in ones, writes the installable ones to a requirements.txt file, and then installs them using pip—in parallel threads for speed.

I use the copilot and some comments are into my language, but I tested and works well:

NOTE: I updated with detection python modules based "from" and another issue: check if python module is instaled and step over that python module ...

This script will try to install many python modules, I can update to be better with these issues:

...some modules are default , some scripts are from another area, see Blender 3D with bpy python modules, some packages comes with same modules, this can be soleved with defined lists with unique items.

Python Qt6 : Use python with ffmpeg tool ...

If you download a video from youtube with high resolution using a tool as yt-dlp then you can get two files with video and audio content:

... one with be with .f401.mp4 and another with .f251-9.webm and using the ffmpeg tool you can create one .mp4 file with both audio and video content.

News : Django Hijack

Log in and work on behalf of other users without having to know their credentials.

With Django Hijack, admins can impersonate and work on behalf of other users without having to know their credentials.

Comes with two versions available: v2.x and v3.x. The last v3.x provides a security first design, easy integration, customisation, out-of-the-box Django admin support and dark-mode. It is a complete rewrite and all former APIs are broken.

News : The geoai-py - part 001.

A powerful Python package for integrating Artificial Intelligence with geospatial data analysis and visualization

GeoAI bridges the gap between AI and geospatial analysis, providing tools for processing, analyzing, and visualizing geospatial data using advanced machine learning techniques. Whether you're working with satellite imagery, LiDAR point clouds, or vector data, GeoAI offers intuitive interfaces to apply cutting-edge AI models.

Today , I tested this python package named geoai-py. I used the pip tool:

Python Qt6 : simple celtic knots tool with SVG file format.

Today, I try to create SVG file with an celtic knot design tool.

I used random values from -360 up to 360 for for Twist 1, Twist 2, and Twist 3 sliders.

The basic function is this, is created by artificial intelligence and not works very well.

        # Generate star polygon vertices
        points_cw = []
        points_ccw = []
        for i in range(steps):
            t = 2 * math.pi * i / steps
            r = outer_radius if i % 2 == 0 else inner_radius
            x_cw = center[0] + r * math.cos(t)
            y_cw = center[1] + r * math.sin(t)
            x_ccw = center[0] + r * math.cos(-t + math.pi / max(lobes, 1))
            y_ccw = center[1] + r * math.sin(-t + math.pi / max(lobes, 1))
            points_cw.append((x_cw, y_cw))
            points_ccw.append((x_ccw, y_ccw))

See one random example with this tool:
