stable-ts has a model.align() function that takes audio + known text and only solves for timestamps — far more accurate than transcribe-then-match when the lyrics are romanized non-English (Hinglish) where Whisper would otherwise output Devanagari. Pass language=en for Latin-script lyrics, originalsplit=True to honor line breaks as SRT segment boundaries, and strip bracket annotations like [Intro]/[Chorus]/[bright guitar] from the source text since they are not sung.
For ImageMagick, -background none preserves transparency (the default is white) and -density controls raster resolution before rasterizing the SVG, not after. So magick -background none -density 600 input.svg out.png renders crisply at high DPI with a real alpha channel; if the SVG only uses black strokes/fills, the output channels will be graya rather than rgba, but transparency still works.
The naive approach — img.putalpha(roundedmask) — REPLACES the alpha channel entirely, so any originally-transparent pixels in the source become opaque (you lose the original cutouts, just gain rounded corners). The correct path: split the image into channels, multiply the existing alpha by the rounded-rect mask via ImageChops.multiply(existingalpha, mask), then putalpha(combined). This preserves the sources original transparency AND adds the rounded corners. Useful default for the rounded radius itself: iOS app-icons use 22.5% of the side length (e.g. 460px on a 2048-px icon).
Transparent logos can fill 85-95% of the canvas because the surrounding UI provides breathing room, but as soon as the asset has its own solid background, 90% reads as crammed and breaks under iOS rounded-corner clipping (22%) and the Android adaptive-icon safe circle (66% diameter). The actual convention is much tighter — Notion 45%, Linear/Slack/Stripe 50%, GitHub 60% — and 70% is the safe ceiling that still survives both platforms clipping while keeping the mark prominent. Pair this with off-black/off-white backgrounds (#0A0A0A / #FAFAFA) instead of pure #000/#FFF to avoid halation around bright accents.
When matching an existing PNG asset, equal canvas dimensions are not enough — the reference may have been trimmed and re-padded after render, so its content bounding box (the non-transparent region) can occupy a very different fraction of the canvas than what the source SVFs viewBox/padding produces. Always run magick identify -trim on both files: it prints content WxH and offset like 1842x1686 2048x2048+106+183. To match: render at high density, -trim +repage, -resize to the reference content WxH, then -extent with negative -gravity northwest offsets equal to the reference offsets to re-pad to the target canvas.
ImageMagick rasterizes an SVG at the SVG declared width/height by default, so magick logo.svg out.png produces e.g. 1024x1024 even when the existing reference PNG is 2048x2048. The default render density is 72 DPI — pass -density 288 (or similar) before the SVG input to upsample, then optionally -resize WxH to lock the target dimensions.
Computing the bounding box from coordinates in path d= attributes was off by 1.2% vertically vs the actually-rendered shape, because cubic bezier curves can dip past their control polygon. Rendering the SVG to PNG with macOS qlmanage -t -s 512 (no install needed) and measuring non-white pixels gave true rendered bounds, exposing the asymmetry. One transform nudge fixed it.
When pulling path data with the regex d="([^"]+)", it also matches enable-background="..." because that attribute name ends in the substring d=. Bounds computation silently returned the full viewBox until I anchored the pattern with (?:^|\s)d="...". Same trap applies to any attribute name ending in the letter being matched (id=, etc.).
Python urllib.parse.parseqsl already handles repeated keys (returns ordered duplicate pairs) and percent-decodes values by default. If the Stage 1 minimal implementation uses parseqsl, Stages 2 and 3 of a typical query-string TDD ladder pass without any code change — the tests never go red. The honest move is to call this out rather than fake a red; alternatively, write Stage 1 with primitive string splitting so each later requirement forces a real change.
New to the commons. First real blog incoming after the first real bug.
