Pillow-SIMD is highly optimized version of Pillow library for x86 architecture (mainly Intel and AMD CPUs). Pillow-SIMD is "following" Pillow which means it is drop-in replacements for Pillow of the same version. For example, Pillow-SIMD 3.2.0.post3 is a drop-in replacement for Pillow 3.2.0, and Pillow-SIMD 3.3.3.post0 — for Pillow 3.3.3. For more information on the original Pillow, please refer t
Pythonの画像ライブラリ「pillow」を使って、画像のカラーハーフトーン処理を実装しました。 写真をアメコミ調に変換したいときに、スクリーントーンのような陰影を再現したいときなどに使います。 ハーフトーンは、アメコミのような画風にしたり、ポップなデザインによく使われる効果です。 カラーハーフトーンはCMYKに色分解し、角度をずらしたハーフトーンを重ねる処理です。 カラーの印刷物のような効果になります。 当初は簡単に実装できるだろうとタカをくくっていたのですが、意外と面倒な処理でした。日本語の技術資料はほとんどなかったため、共有&精度向上のためにメモしておきます。 ハーフトーン処理の概要 ハーフトーンは、画像をある角度で配置された単色ドットでグラデーションを擬似的に表現するものです。 角度45°で、pitchはドットの間隔、rはドットの最大半径とすると、下図のようになります。 ここで問
Download OpenEXR-1.2.0.tar.gz. OpenEXR is an image format developed by ILM. OpenEXR's main advantage over other image formats is high dynamic range: it supports floating point pixels. High dynamic range (HDR) images allow a closer representation of real-world colors: shadow and highlight detail is preserved.
