  • OptiPNG Shell Integration: Fast Lossless PNG Optimization from the Command Line

    Automating PNG Compression: OptiPNG Shell Integration Guide

    Overview

    OptiPNG is a lossless PNG optimizer that recompresses image files to smaller sizes without quality loss. This guide shows how to automate PNG compression by integrating OptiPNG into shell workflows for single files, directories, and CI pipelines.

    Prerequisites

    • Install OptiPNG (Linux/macOS: package manager; Windows: binaries).
    • Basic shell knowledge (bash, zsh, or sh).
    • Optional: find, xargs, parallel, Git, CI provider (GitHub Actions, GitLab CI, etc.).

    Basic Commands

    • Compress a single file:

    bash

    optipng -o7 image.png
    • Show help:

    bash

    optipng -h

    Batch Processing

    • Compress all PNGs in a directory (non-recursive):

    bash

    for f in.png; do optipng -o7 \(f</span><span class="token" style="color: rgb(163, 21, 21);">"</span><span class="token" style="color: rgb(57, 58, 52);">;</span><span> </span><span class="token" style="color: rgb(0, 0, 255);">done</span><span> </span></code></div></div></pre> <ul> <li>Recursive using find:</li> </ul> <pre><div class="XG2rBS5V967VhGTCEN1k"><div class="nHykNMmtaaTJMjgzStID"><div class="HsT0RHFbNELC00WicOi8"><i><svg width="16" height="16" fill="none" xmlns="http://www.w3.org/2000/svg"><path fill="currentColor" fill-rule="evenodd" clip-rule="evenodd" d="M15.434 7.51c.137.137.212.311.212.49a.694.694 0 0 1-.212.5l-3.54 3.5a.893.893 0 0 1-.277.18 1.024 1.024 0 0 1-.684.038.945.945 0 0 1-.302-.148.787.787 0 0 1-.213-.234.652.652 0 0 1-.045-.58.74.74 0 0 1 .175-.256l3.045-3-3.045-3a.69.69 0 0 1-.22-.55.723.723 0 0 1 .303-.52 1 1 0 0 1 .648-.186.962.962 0 0 1 .614.256l3.541 3.51Zm-12.281 0A.695.695 0 0 0 2.94 8a.694.694 0 0 0 .213.5l3.54 3.5a.893.893 0 0 0 .277.18 1.024 1.024 0 0 0 .684.038.945.945 0 0 0 .302-.148.788.788 0 0 0 .213-.234.651.651 0 0 0 .045-.58.74.74 0 0 0-.175-.256L4.994 8l3.045-3a.69.69 0 0 0 .22-.55.723.723 0 0 0-.303-.52 1 1 0 0 0-.648-.186.962.962 0 0 0-.615.256l-3.54 3.51Z"></path></svg></i><p class="li3asHIMe05JPmtJCytG wZ4JdaHxSAhGy1HoNVja cPy9QU4brI7VQXFNPEvF">bash</p></div><div class="CF2lgtGWtYUYmTULoX44"><button type="button" class="st68fcLUUT0dNcuLLB2_ ffON2NH02oMAcqyoh2UU MQCbz04ET5EljRmK3YpQ CPXAhl7VTkj2dHDyAYAf" data-copycode="true" role="button" aria-label="Copy Code"><svg viewBox="0 0 16 16" fill="none" xmlns="http://www.w3.org/2000/svg"><path fill="currentColor" fill-rule="evenodd" clip-rule="evenodd" d="M9.975 1h.09a3.2 3.2 0 0 1 3.202 3.201v1.924a.754.754 0 0 1-.017.16l1.23 1.353A2 2 0 0 1 15 8.983V14a2 2 0 0 1-2 2H8a2 2 0 0 1-1.733-1H4.183a3.201 3.201 0 0 1-3.2-3.201V4.201a3.2 3.2 0 0 1 3.04-3.197A1.25 1.25 0 0 1 5.25 0h3.5c.604 0 1.109.43 1.225 1ZM4.249 2.5h-.066a1.7 1.7 0 0 0-1.7 1.701v7.598c0 .94.761 1.701 1.7 1.701H6V7a2 2 0 0 1 2-2h3.197c.195 0 .387.028.57.083v-.882A1.7 1.7 0 0 0 10.066 2.5H9.75c-.228.304-.591.5-1 .5h-3.5c-.41 0-.772-.196-1-.5ZM5 1.75v-.5A.25.25 0 0 1 5.25 1h3.5a.25.25 0 0 1 .25.25v.5a.25.25 0 0 1-.25.25h-3.5A.25.25 0 0 1 5 1.75ZM7.5 7a.5.5 0 0 1 .5-.5h3V9a1 1 0 0 0 1 1h1.5v4a.5.5 0 0 1-.5.5H8a.5.5 0 0 1-.5-.5V7Zm6 2v-.017a.5.5 0 0 0-.13-.336L12 7.14V9h1.5Z"></path></svg>Copy Code</button><button type="button" class="st68fcLUUT0dNcuLLB2_ WtfzoAXPoZC2mMqcexgL ffON2NH02oMAcqyoh2UU MQCbz04ET5EljRmK3YpQ GnLX_jUB3Jn3idluie7R"><svg fill="none" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg"><path fill="currentColor" fill-rule="evenodd" d="M20.618 4.214a1 1 0 0 1 .168 1.404l-11 14a1 1 0 0 1-1.554.022l-5-6a1 1 0 0 1 1.536-1.28l4.21 5.05L19.213 4.382a1 1 0 0 1 1.404-.168Z" clip-rule="evenodd"></path></svg>Copied</button></div></div><div class="mtDfw7oSa1WexjXyzs9y" style="color: var(--sds-color-text-01);

    Integration with Build/CI

    • GitHub Actions example (compress PNGs in repo):

    yaml

    name: OptiPNG on: [push, pullrequest] jobs: optimize: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - run: sudo apt-get update && sudo apt-get install -y optipng - run: | find . -type f -iname ‘*.png’ -print0 | xargs -0 -n1 optipng -o7 - run: | git config user.name “optipng-bot” git config user.email “[email protected] git add -A git commit -m “Optimize PNGs” || echo “No changes” git push || echo “Push failed”
    • CI tips: run on image-heavy branches, limit to changed files (use git diff), use artifacts to inspect results.

    Useful Options & Tips

    • Optimization level: -o1..-o7 (higher = slower, smaller).
    • Preserve metadata: use –strip option (e.g., –strip all) to remove ancillary chunks if desired.
    • Dry run: compare sizes before/after with du or identify (ImageMagick).
    • Performance: use -preserve or control I/O to avoid recompressing already-optimized files (compare checksums or sizes).
    • Error handling: check exit codes; wrap in scripts that log failures.

    Example Script: Optimize Only Changed PNGs

    • Track bytes saved and percentage reduction for CI reports.

    Troubleshooting

    • Corrupt output: test files with pngcheck.
    • Long runtimes: lower optimization level or parallelize.
    • Permission issues: ensure write access or output to separate directory.

    Best Practices

    • Run optipng as part of CI or a pre-commit hook for consistency.
    • Keep originals or use git history instead of permanent overwrites.
    • Limit aggressive stripping if metadata (ICC, text) is needed.

    If you want, I can generate a ready-to-use pre-commit hook, a GitHub Action file that only optimizes changed PNGs, or a one-file script tuned to your repo size.

  • Desk Games Icon Set

    Desk Games Icon Set

    A well-designed icon set can instantly communicate a product’s purpose, tone, and usability. The Desk Games Icon Set is a versatile collection of icons created for designers, developers, and hobbyists who need clean, recognizable visual assets for board games, tabletop tools, productivity apps, or gaming websites. This article describes what the set includes, design principles, use cases, file formats, and quick tips for integrating the icons into projects.

    What’s included

    • 60 core icons covering common desk-game elements: dice, cards, tokens, meeples, boards, timers, score sheets, rulebooks, trays, and cups.
    • 30 accessory icons: pencils, rulers, magnifiers, badges, achievement stars, and UI symbols (play, pause, settings).
    • Three stylistic variants for each icon: flat color, line stroke, and filled glyph.
    • Multiple sizes: 16px, 24px, 48px, 96px raster exports and fully scalable SVGs.
    • Color palette file (HEX values) and an editable Figma/Sketch source file.

    Design principles

    • Clarity: Each icon uses simplified shapes to remain legible at small sizes.
    • Consistency: Shared stroke widths, corner radii, and visual weight create a cohesive set.
    • Scalability: Vector-first workflow ensures crisp rendering across resolutions.
    • Accessibility: Sufficient contrast and distinct silhouettes help users with low vision differentiate icons.

    Primary use cases

    • Board-game companion apps and rulebook PDFs.
    • App UI and web interfaces for tabletop marketplaces or game management tools.
    • Marketing materials, product pages, and icons in print-on-demand game inserts.
    • Prototyping in Figma, Sketch, or Adobe XD using the provided components.

    File formats & technical details

    • SVG (editable vectors), PNG (multiple resolutions), and a single icon font (TTF/WOFF) for UI use.
    • Layered source in Figma and Sketch with organized naming and auto-layout for quick swaps.
    • Production-ready exports with optimized SVGs (no unnecessary metadata), and PNGs exported with transparent backgrounds.

    Integration tips

    1. Use the line variant for toolbars and the filled variant for system states (active/selected).
    2. Keep icon sizing consistent: 24px for compact toolbars, 48px for feature highlights.
    3. Tweak colors by swapping palette tokens in Figma rather than editing individual SVGs.
    4. When converting to an icon font, map semantic names (e.g., game-dice, game-card) to maintain clarity in code.
    5. Use SVG sprites or a component library to reduce HTTP requests and keep performance optimal.

    Licensing & distribution

    • Typical licensing options include personal use, commercial use, and extended bundles for resellers. Ensure the license matches the intended distribution (e.g., embedding in paid apps vs. including in a game you sell).

    Quick example: implementing an icon in HTML (SVG inline)

    html

    <button class=icon-btn aria-label=Roll dice> <svg width=24 height=24 viewBox=0 0 24 24 role=img aria-hidden=true></svg> </button>

    Conclusion

    The Desk Games Icon Set streamlines UI design for tabletop and desk-game-related products by providing a coherent, scalable collection of icons tailored to common game elements. With multiple styles, editable sources, and clear usage guidance, it helps teams move faster from prototype to polished UI while maintaining visual consistency.

  • Gmail Inbox Notifier

    Gmail Inbox Notifier: Real-Time Alerts for New Emails

    What it is

    • A Gmail Inbox Notifier is a tool or feature that alerts you immediately when new messages arrive in your Gmail account. Alerts can appear as desktop notifications, mobile push notifications, browser badges, or system tray icons.

    How it works (overview)

    1. Connects to Gmail via IMAP, Gmail API, or OAuth-authenticated access.
    2. Monitors the Inbox folder for new message events or polls at short intervals.
    3. Triggers a local notification (toast/push) or updates an icon/badge when a new email is detected.
    4. Optionally shows sender, subject, and a preview; may include quick actions (archive, mark read).

    Common notification types

    • Desktop toast (Windows/macOS/Linux)
    • Browser push (Chrome, Firefox, Edge)
    • Mobile push (iOS/Android apps)
    • System tray / menu bar icon with unread count
    • Email client badges and lock-screen previews

    Key features to look for

    • Real-time or near-real-time detection (push via Gmail API or IMAP IDLE preferred)
    • Secure authentication (OAuth 2.0, no storing raw passwords)
    • Custom filtering (notify only for certain senders, labels, or keywords)
    • Privacy controls (hide message previews, mute hours)
    • Actionable notifications (archive, reply, mark read from the notification)
    • Low resource use (efficient background operation)

    Setup options

    • Built-in Gmail notifications (web/mobile): enable in Gmail settings and browser/OS notification permissions.
    • Third-party apps/extensions: browser extensions or small desktop apps that use Gmail API or IMAP.
    • Custom scripts: use IMAP IDLE or Gmail push notifications via the Gmail API for developers to build tailored notifiers.

    Troubleshooting common issues

    • No notifications: check notification permissions in OS/browser and Gmail settings.
    • Delayed alerts: switch from polling to IMAP IDLE or Gmail push; ensure background app refresh is enabled on mobile.
    • Duplicate alerts: revoke and reauthorize app access or remove multiple notification sources.
    • Security warnings: prefer apps using OAuth; avoid giving apps full account passwords.

    Privacy & security tips

    • Use OAuth-based apps and review OAuth permissions in your Google Account.
    • Limit notification content (disable previews) when on shared or public devices.
    • Revoke access for unused apps in Google Account > Security > Third-party apps.

    If you want, I can:

    • Provide step-by-step setup for Gmail web/browser notifications.
    • Recommend lightweight notifier apps or browser extensions.
    • Share a short script example using IMAP IDLE or the Gmail API.
