Kotlin Multiplatform color picker library for getting colors from any images by tapping on the desired color (mirror) https://git.radix-linux.su/Android/colorpicker-compose.git/atom?h=main 2026-09-16T09:25:40+00:00 2026-09-16T09:25:40+00:00 skydoves skydoves2@gmail.com 2026-09-16T09:25:40+00:00 urn:sha1:ecacbb1fed28ddc0dfc909d186ccab4708cc42cb A boolean goes wrong as soon as two sliders of the same kind share a controller: the first one to leave the composition clears it while the other is still on screen, and the surviving slider stops reaching the color. The controller counts them now, and the last one out is what hands the component back to the palette color. Adds regression tests for both, four of which fail when a slider that leaves stays attached, and two when one leaving speaks for the other. 2026-09-16T09:22:00+00:00 skydoves skydoves2@gmail.com 2026-09-16T09:22:00+00:00 urn:sha1:00e80ba53e173031705477716874cf5c0ec68a33 2026-09-16T09:09:24+00:00 skydoves skydoves2@gmail.com 2026-09-16T09:09:15+00:00 urn:sha1:b412754c65e7cbf76aa77401e7ce57324a7aeb0c Resolutions: - Took main for the Spotless bump, the ktlint reformats, the version catalog and the wheel bitmap property, all of which landed separately. - Kept the benchmark build type and the baselineProfile dependency on :demo:androidApp, which the baseline-profile workflow needs. - ObserveColorChanges now uses rememberCoroutineScope as well, so the picker and the sliders collect the same way, and ColorPicker just delegates to it. - Tests build the controller without a scope, and the ones that read a callback wait for idle first, since a color change now arrives on the composition's own scope rather than Dispatchers.Main. 2026-09-16T08:48:05+00:00 skydoves skydoves2@gmail.com 2026-09-16T07:57:32+00:00 urn:sha1:01826f9c8d8425384aded2ba0030880d9b388365 AGP 9.3.2 to 9.4.0, Kotlin 2.4.10 to 2.4.20, Compose Multiplatform 1.11.1 to 1.12.0, binary compatibility validator 0.18.1 to 0.18.2, macrobenchmark off its alpha, Spotless 6.21.0 to 8.10.2 and the Gradle wrapper 9.6.1 to 9.7.1. Compose 1.12.0 asks for compileSdk 37. Spotless 8 brings a newer ktlint, which reformats a few files, wants screaming snake case for a const in the benchmark, and needs to be told that a Composable is named like a type. 2026-09-16T08:01:41+00:00 skydoves skydoves2@gmail.com 2026-09-16T07:46:40+00:00 urn:sha1:f03c885773213b5b9bb2eb9a78fe81fe15666bf0 onColorChanged fires for every step of a drag, so there was no way to tell a live preview apart from a finished choice. HsvColorPicker and ImageColorPicker now take onColorPickingFinished, which fires once when a tap lands or a drag ends, with the color the pick settled on. 2026-09-16T08:01:41+00:00 skydoves skydoves2@gmail.com 2026-09-16T07:45:05+00:00 urn:sha1:0e39c876c10b1bc879b49e6237a7248ad3fa59c7 - The thumb was centered on the track ends, so half of it was clipped away. It now reserves its radius at each end, and the tap and drag mapping uses the same travel. - The track paint took its color, and so its alpha, from the controller. A controller with nothing selected is transparent, which left a slider used without a picker drawing nothing at all. - The brightness ramp assumed full saturation and painted red instead of a grey ramp when nothing was selected. - AlphaSlider, BrightnessSlider and SaturationSlider take onColorChanged so they report without a picker beside them. - Every slider takes an orientation and can run bottom to top. - The slider and tile backgrounds are no longer rebuilt on every recomposition, and the initial value is no longer written during the draw phase. 2026-09-16T08:01:41+00:00 skydoves skydoves2@gmail.com 2026-09-16T07:36:12+00:00 urn:sha1:3fec6c88a45c9657d4a6bc30f1b9a09a58439e1e A palette scaled to fit leaves bands beside it, and the picker used to clamp a tap there onto the nearest edge pixel and report it as a color. Fully transparent pixels came back as a selection too, which is the transparent pixel TODO the original Android version handled by skipping them. Both now leave the selection alone. 2026-09-16T08:01:14+00:00 skydoves skydoves2@gmail.com 2026-09-16T07:33:23+00:00 urn:sha1:579bf557f32afd5381375c9ffa5881e96a059ab1 - The canvas size setter divided by a zero size on the first layout pass and produced Offset(NaN, NaN), which is Offset.Unspecified, so drawing the wheel threw whenever setup could not overwrite it. - setup() now leaves the current selection alone when a picker registers itself again, which happens on every recomposition if the palette is built inline. - HsvColorPicker replays initialColor so its value and alpha survive. - selectByColor before the first layout is held and applied once the picker is ready instead of being dropped. - wheelImageBitmap is kept in step with the controller and is snapshot state, so a new bitmap repaints. 2026-09-16T08:00:26+00:00 skydoves skydoves2@gmail.com 2026-09-16T07:27:29+00:00 urn:sha1:5b40aba1b64e058a90d1951efe36c2c9095fda12 Wires up commonTest and desktopTest with kotlin-test and the Compose multiplatform ui-test artifact, and covers the color math, the geometry helpers, the controller, both pickers, the sliders and the alpha tile. The web targets skip tests because ColorPickerController builds a Paint eagerly and Kotlin/JS cannot load Skiko in a Node or headless run. CI gains a job for them, and drops the branch filter on pull_request so that a pull request stacked on another one gets checked too. 2026-07-20T23:48:25+00:00 Azerlag candro.kutcia@yandex.com 2026-07-20T23:48:25+00:00 urn:sha1:a94f41214d10198df6f795b0a9a08a9490a0ad72
