A look inside PicDraw Grid.
What It Does
Everything PicDraw Grid brings to the table.
📁
Albums → Gallery → Viewer
Browse albums, then a gallery grid, then a swipeable full-screen viewer powered by SubsamplingScaleImageView for huge images.
🔲
Four Grid Types
Rule of Thirds, Custom, Pixel Grid and Golden Ratio — with colour, opacity, thickness and a closed border.
🎚️
B&W Effects
Hardware-accelerated ColorMatrix B&W with five presets plus brightness, contrast, R/G/B mix and grain.
⛶
Immersive Full Screen

🔍
Pinch to Zoom
Native pinch-zoom on high-resolution images without running out of memory.
