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)

        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 3.10.7 : Krita and python - part 001.

Here is a Python script for Krita that will help you read the Python functions of a document.

Open a new document, create a python script, and add the source code. Use the main menu Tools - Scripts - Ten Scripts to choose the place where the script exists and the combination of keys for execution.

This is the source code:

from PyQt5.QtWidgets import QWidget, QVBoxLayout, QTreeWidget, QTreeWidgetItem, QTextEdit
from krita import *

class LayerContentDialog(QWidget):
    def __init__(self, content):
        super().__init__()
        self.setWindowTitle("Conținutul preluat cu dir():")
        self.setGeometry(100, 100, 800, 600)

        main_layout = QVBoxLayout()

        tree_widget = QTreeWidget()
        tree_widget.setHeaderLabels(["Nume", "Tip"])
        self.add_items_recursive(tree_widget, content)
        main_layout.addWidget(tree_widget)

        close_button = QPushButton("Închide")
        close_button.clicked.connect(self.close)
        main_layout.addWidget(close_button)

        self.setLayout(main_layout)

    def add_items_recursive(self, tree_widget, items, parent_item=None):
        for item in items:
            if isinstance(item, str):
                if parent_item:
                    item_widget = QTreeWidgetItem(parent_item, [item, type(getattr(doc, item)).__name__])
                    help_text = "\n".join(dir(getattr(doc, item)))
                    item_widget.addChild(QTreeWidgetItem([help_text]))
                else:
                    item_widget = QTreeWidgetItem(tree_widget, [item, type(getattr(doc, item)).__name__])
                    help_text = "\n".join(dir(getattr(doc, item)))
                    item_widget.addChild(QTreeWidgetItem([help_text]))
            elif isinstance(item, type):
                parent = QTreeWidgetItem(tree_widget, [item.__name__, "Modul"])
                self.add_items_recursive(tree_widget, dir(item), parent)

doc = Krita.instance().activeDocument()
layerContents = dir(doc)

dialog = LayerContentDialog(layerContents)
dialog.show()

The result for this script is this:

You can use the main menu Tools - Scripts - Scripter to write, test, save, and run the source code.

Python 3.7.3 : Programming Krita.

Today I wrote a python tutorial about Krita software and programming python.
The Krita software use python version 3.6.2.

==== Warning: Script not saved! ====
3.6.2 (v3.6.2:5fd33b5, Jul  8 2017, 04:57:36) [MSC v.1900 64 bit (AMD64)]

The full tutorial can be found at my Blogspot (a Blogspot about the graphics area).
