From 7d59e2b2c1c96988a6f04d4bf3c601e882f00efd Mon Sep 17 00:00:00 2001 From: "FeRD (Frank Dana)" <ferdnyc@gmail.com> Date: Wed, 22 May 2024 04:54:49 -0400 Subject: [PATCH] Icons: Make PNG/XPM transparent, hi-res Extend the ImageMagick `convert` commands for generating icon bitmaps: - Add `-background none`, to render with background transparency. - Add `-density 300x300`, to render larger sizes at full resolution. Because the SVG's internal coordinate system is only sized for 64x64 pixels, ImageMagick will render at that size and then scale the _bitmap_ up, when outputting larger image sizes. Increasing the DPI using `-density` allows it to upscale the SVG vectors at full resolution.
