NaraMotion + +> **NOTE FOR AI CODING ASSISTANTS (ChatGPT, Claude, Gemini, DeepSeek, Cursor, Copilot, Kaggle)**: +> This document defines the strict architectural rules, API standards, and execution patterns for writing code using **NaraMotion** (`import naramotion as nm` or `from naramotion import ...`). + +--- + +## 🛑 1. The Cardinal Rule: 100% Native & Self-Contained Engine + +**NaraMotion is an All-in-One Super Engine** combining JIT-accelerated vector drawing, cinematic visual FX, motion graphics, 2.5D perspective camera, particle physics, GIS mapping, multi-threaded Parquet ingestion, and hardware video encoding into a single native C++ pipeline. + +### ⛔ BANNED EXTERNAL LIBRARIES (DO NOT USE): +| Prohibited Library | Reason | Native NaraMotion Replacement | +| :--- | :--- | :--- | +| `import cv2` (OpenCV) | Redundant & slow memory copies | `from naramotion.fx import bloom, neon_glow, gaussian_blur, box_blur_integral, chromatic_aberration, color_grade, tone_map_aces` | +| `import moviepy` / `imageio` | Inefficient Python video wrappers | `from naramotion.video import VideoWriter` or direct `img.buffer` pipe | +| `from PIL import Image` | Unnecessary wrapper overhead | `from naramotion import Image, Context` (includes `to_pil()` / `from_pil()`) | +| `import matplotlib.pyplot` | Slow vector rendering | `from naramotion.shapgeo import GeoCanvas` or `ctx.stroke_line_array` | +| `import scipy.ndimage` | External filter dependency | `from naramotion.fx import FXPipeline, gaussian_blur, box_blur, box_blur_integral` | +| `import pyproj` | Heavy external projection dependency | `from naramotion.shapgeo import Transformer, reproject_gdf` (Native C++ Proj Engine) | + +--- + +## 🔑 2. Mandatory Commercial License Activation + +Every standalone script or notebook cell must begin by activating the license: + +```python +import naramotion as nm + +# 1. Activate License (Bypasses evaluation watermark) +nm.set_license("08032008is") +``` + +--- + +## 🗺️ 3. Native Module Directory & Import Map + +```python +# 1.

Zero-Copy Hardware Video Encoder & Reader +from naramotion.video import VideoWriter, VideoReader, record_animation +``` + +--- + +## 🎬 4. Core Motion & Declarative Kinetic Suite + +### Declarative Reveal Actions (`Create`, `ShowCreation`, `Uncreate`): +```python +from naramotion.motion import Create, ShowCreation, Uncreate, Timeline + +timeline = Timeline(fps=60) +timeline.add_action(Create(road_path, duration=2.5, easing=Easing.cubic_out), start_time=0.0) +``` + +### Chaikin's Corner Smoothing (Native C++ Curve Curvature Continuous): +```python +from naramotion.motion import chaikin_smooth + +# Smooth raw polygon/linestring/coords in C++ in 0.01ms +smooth_geometry = chaikin_smooth(raw_road_geometry, iterations=2) +``` + +### Interpolation & Extrapolation Remapping: +```python +from naramotion.motion import interpolate, Extrapolate + +# Piecewise remapping with clamping or bounce +val = interpolate(progress, [0.0, 0.5, 1.0], [0.0, 100.0, 50.0], extrapolate=Extrapolate.CLAMP) +``` + +### Distributed Temporal Composition (`Sequence`, `delay_render`): +```python +from naramotion.motion import Sequence, Composition, delay_render + +seq = Sequence(from_frame=60, duration_frames=180) +``` + +--- + +## 🗺️ 5. Geospatial Super-Engine (Structure of Arrays, Dual-Buffer, Spring Pop-in) + +### 1. Structure of Arrays (SoA) & Path Memory Arena (`NativeGeoLayerSoA`): +Pre-allocates city blocks in contiguous C++ cache lines (`distances`, `bboxes`, `paths`, `centroids`, `start_frames`), eliminating heap jitter: +```python +from naramotion import NativeGeoLayerSoA + +layer = NativeGeoLayerSoA(capacity=50000) +layer.from_wkb_batch(wkb_list, transform=canvas.transform) +layer.compute_propagation(epicenters=[(-74.0060, 40.7128)], duration_frames=300.0) +``` + +### 2. Dual-Buffer Polygon Rendering & Centroid Spring Pop-in: +> **PERFORMANCE RULE**: Group fills into Pass 1 and strokes into Pass 2 to keep Blend2D JIT pipelines 100% hot (2.5x faster). Animate expansion via `popin=True` ($Scale(t) = \text{Easing::back\_out}(t)$) centered on feature centroids: +```python +with GeoCanvas(width=3840, height=2160, bg_color="#030408") as canvas: + canvas.crop_and_fit(min_lon, min_lat, max_lon, max_lat, aspect_ratio=16/9) + + with VideoWriter("output_4k.mp4", 3840, 2160, fps=60) as vw: + for frame in range(300): + canvas.clear_frame("#030408") # Fast memset clear in 0.4ms + + # Dual-buffer batch render with elastic spring pop-in + layer.render_popin( + canvas, current_frame=frame, + fill_color="#00F0FF", stroke_color="#FFFFFF", stroke_width=1.0 + ) + + # Zero-copy pipe stream directly to FFmpeg stdin + vw.write_frame(canvas.image) +``` + +### 3. Flat Uniform Grid Spatial Indexing (`UniformGridIndex`): +```python +from naramotion import UniformGridIndex + +grid = UniformGridIndex(bounds=(-74.1, 40.6, -73.8, 40.9), grid_w=64, grid_h=64) +grid.build_from_bboxes(bboxes) +visible_ids = grid.query_bbox(-74.01, 40.70, -73.98, 40.75) # < 1 microsecond! +``` + +### 4. Zero-Object Native Parquet / WKB Ingestion: +```python +import naramotion as nm + +# Streams WKB directly into C++ SoA layers bypassing Python/Shapely completely +layer = nm.read_parquet_native("nyc_blocks.parquet", return_native_soa=True) +``` + +### 5. Fast Built-in Metric Projection (Proj Engine): +```python +# C++ SIMD transformations for EPSG:4326, 3857, 2263, 5070, and UTM +projected = nm.reproject_gdf(gdf, target_crs="EPSG:2263") +``` + +### 6. 4K Ultra-Fast Hierarchical Downsampled Bloom: +```python +from naramotion.fx import bloom + +# Multi-threaded pyramid downsampling runs in < 60ms on full 4K frames +bloom(canvas.image, threshold=0.4, intensity=1.5, radius=16.0) +``` + +--- + +## 🎯 6. AI Code Validation Checklist + +Before presenting NaraMotion code to the user, ensure: +1. `naramotion.set_license("08032008is")` is present. +2. NO `cv2`, `PIL`, `pyproj`, or `moviepy` are imported. +3. For video loops, instantiate `GeoCanvas` ONCE outside the loop and reuse via `canvas.clear_frame(...)`. +4. For polygon blocks/roads in animations, pre-compile with `canvas.create_retained_layer(...)` or `NativeGeoLayerSoA(...)`. +5. For animated building reveals, utilize `layer.render_popin(...)` or `dual_buffer=True`. +6. Visual FX use `naramotion.fx.*` or `FXPipeline`. +7. Video export uses `naramotion.video.VideoWriter` or direct `img.buffer` pipe. diff --git a/DOCUMENTATION.md b/DOCUMENTATION.md new file mode 100644 index 0000000000000000000000000000000000000000..b8a80c712e54d6dc1a5242d23607fd332a093a79 --- /dev/null +++ b/DOCUMENTATION.md @@ -0,0 +1,889 @@ +# NaraMotion Complete API Documentation & Reference Guide 📚✨ + +**Author & Creator**: Islam Arifi +**Official PyPI Package**: [`naramotion`](https://pypi.org/project/naramotion/) (v0.26.0) +**Core Engine**: Powered by Blend2D (Native C++ JIT Compiler & SIMD Hardware Acceleration) +**License**: Proprietary Commercial License (with Evaluation Mode) + + +--- + +## 📑 Table of Contents + +1.

Comprehensive Error Catalog, Exceptions & Troubleshooting Guide + +NaraMotion wraps all native C++ engine errors into standard Python exceptions. Below is the complete catalog of errors, their root causes, and step-by-step resolution. + +### 22.1 Native Engine Errors (`naramotion.Blend2DError`) + +| Error Code | Exception Output | Root Cause | Resolution | +| :--- | :--- | :--- | :--- | +| **`BL_ERROR_INVALID_VALUE` (1)** | `Blend2DError: Invalid value` | Passing invalid image width/height ($\le 0$), negative radius, NaN, or Inf coordinates. | Ensure dimensions are integers $> 0$ and coordinates are valid finite numbers (`math.isfinite(x)`). | +| **`BL_ERROR_INVALID_STATE` (2)** | `Blend2DError: Invalid state` | Calling drawing methods on a context after `ctx.end()`, or before `ctx.begin()`. | Always use the context manager `with Context(img) as ctx:` which guarantees safe lifecycle. | +| **`BL_ERROR_INVALID_HANDLE` (3)** | `Blend2DError: Invalid handle` | Calling methods on a destroyed image/path resource (e.g. after `img.reset()`). | Do not access an image after calling `img.reset()`. Create a new image if needed. | +| **`BL_ERROR_NO_MATCHING_VERTEX` (4)** | `Blend2DError: No matching vertex` | Attempting to trim or query path tangent on an empty `Path()`. | Ensure the path contains at least one `move_to` and `line_to` before calling `trim_path()` or `PathFollower`. | +| **`BL_ERROR_OUT_OF_MEMORY` (6)** | `Blend2DError: Out of memory` | Requesting an image allocation larger than available RAM (e.g. $100000 \times 100000$). | Verify image dimensions before creating canvas. For large maps, render in tiles or at 4K/8K. | +| **`BL_ERROR_FONT_NOT_MATCHED` (14)** | `Blend2DError: Font not matched` | Passing a corrupted font file or unsupported font format. | Provide a standard OpenType (`.otf`) or TrueType (`.ttf` / `.ttc`) font file. | + +--- + +### 22.2 Common Python Exceptions in NaraMotion + +#### 1. `ValueError: Unsupported color format` +- **When it happens**: Passing CSS functional strings like `"rgba(255, 0, 0, 0.5)"` or `"rgb(0, 255, 0)"`. +- **Fix**: Convert to hex string or numeric tuple: + ```python + # ❌ Incorrect: + ctx.fill_circle(100, 100, 50, "rgba(56, 189, 248, 0.5)") + + # ✅ Correct: + ctx.fill_circle(100, 100, 50, "#38BDF880") # Hex with 50% alpha + ctx.fill_circle(100, 100, 50, (56, 189, 248, 128)) # Tuple with alpha + ``` + +#### 2. `RuntimeError: FFmpeg executable not found` +- **When it happens**: Using `VideoWriter` or `VideoReader` when FFmpeg is not installed or not in system `PATH`. +- **Fix**: + - **Windows**: `winget install Gyan.FFmpeg` + - **Ubuntu / Debian**: `sudo apt update && sudo apt install -y ffmpeg` + - **macOS**: `brew install ffmpeg` + +#### 3. `TypeError: Array must be C-contiguous and uint8` +- **When it happens**: Passing a non-contiguous slice or float array to `Image.from_numpy()`. +- **Fix**: Ensure array is C-contiguous with `uint8` dtype: + ```python + import numpy as np + arr = np.ascontiguousarray(arr, dtype=np.uint8) + img = Image.from_numpy(arr) + ``` + +#### 4. `FileNotFoundError: Font file not found` +- **When it happens**: Calling `FontFace.from_file("arial.ttf")` when the file does not exist at that path. +- **Fix**: Use absolute paths: + ```python + # Windows: + face = FontFace.from_file("C:/Windows/Fonts/segoeui.ttf") + # Linux: + face = FontFace.from_file("/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf") + ``` + +#### 5. `ImportError: DLL load failed while importing _bin` +- **When it happens**: Missing Visual C++ runtime on Windows. +- **Fix**: Install the official [Microsoft Visual C++ 2015-2022 Redistributable (x64)](https://aka.ms/vs/17/release/vc_redist.x64.exe) or reinstall with: + ```bash + pip install --force-reinstall naramotion + ``` + +--- + +### 22.3 Environment Conflicts & Compatibility Solutions + +| Environment Issue | Cause | Solution | +| :--- | :--- | :--- | +| **GeoPandas / Shapely version mismatch** | Old versions missing `__geo_interface__` | `pip install --upgrade geopandas shapely` | +| **Virtualenv DLL isolation** | Custom sandbox blocking `.dll` search | NaraMotion auto-adds `blend2d/_bin` with `os.add_dll_directory()`. | +| **Multithreading OpenMP / Context Sharing** | Two threads drawing to the same `Context` simultaneously | Create one `Context` per image per thread. Images can be rendered in parallel across threads. | diff --git a/README.md b/README.md new file mode 100644 index 0000000000000000000000000000000000000000..96c5aa33a28a15e4fe6b31a357aaf9e18a603ee6 --- /dev/null +++ b/README.md @@ -0,0 +1,128 @@ +# NaraMotion 🎨🚀 + +[![Python Version](https://img.shields.io/badge/python-3.8+-blue.svg)](https://www.python.org/) +[![License](https://img.shields.io/badge/License-Proprietary-red.svg)](https://pypi.org/project/naramotion/) +[![JIT Accelerated](https://img.shields.io/badge/JIT-AsmJit%20Hardware%20Accelerated-orange.svg)](https://blend2d.com) + +**Author & Creator**: Islam Arifi +**Official PyPI Package**: [`naramotion`](https://pypi.org/project/naramotion/) (v0.22.0) + +**NaraMotion** is an ultra-fast 2D/2.5D vector graphics, GIS, motion graphics, and cinematic video engine for Python powered by **[Blend2D](https://blend2d.com)** (embedded JIT compiler and SIMD hardware acceleration). + +--- + +## 🔑 License Activation & Evaluation Mode + +NaraMotion is distributed under a **Proprietary Commercial License** with an Evaluation Mode. +Unlicensed evaluation renders include a subtle semi-transparent `"Auras"` watermark in the center. + +### To Activate Full Commercial Version: +Call `naramotion.set_license()` at the beginning of your program with your commercial key: + +```python +import naramotion + +# Activate official license (removes all evaluation watermarks) +naramotion.set_license("YOUR_COMMERCIAL_KEY") +``` + +Or set the environment variable: +```bash +export NARAMOTION_LICENSE_KEY="YOUR_COMMERCIAL_KEY" # Linux/macOS +set NARAMOTION_LICENSE_KEY="YOUR_COMMERCIAL_KEY" # Windows +``` + +--- + +## 📦 Official Installation + +### 1.
