v0.3.3 (Chronoscope 2.11/2.12) - 9-Apr-2021
- disable experimental feature
-
v0.3.2 - Mar 2021
- meanwhile 'default' equals 'max', performance is suffering
hence use 'thumbs' for thumbnais, allthough they are too small (140px).
-
v0.3.1 - 25-Nov-2020
- Signature filter in Layout mode; "-LX" by default (no GWLB maps by deaualt)
-
v0.3 - 8-Nov-2020…
- mods:dateIssued >> map.year
- Chronoscope Console: setPrefixFilter("Lx")
-
v0.2 - 31-Oct-2020…
- increase box by 160% to mitigate the margin error >> chronoscope29.js::initMapsDB
- increase to default/max resolution
- MxLB was taken. Rename prefix to MxLH />> LH
Feedback
Pros
- high resolution maps
- better fit of the map area
Cons
- high resolution takes more badwidth to load
- some maps are to big to be displayed
- manual adoption for Chronoscope
- sometimes to huge files for Firefox-WebGL, e.g. LH100665446
- IIIF is planned for 2021
-
v0.1 - 28-Oct-2020
- JS plug v0.1 to load all maps and convert into Chronoscope’s gMapsDB format.
- Console. ggood (1976), gbad (189)
Console: doDownload()
- clean coordniate values – remove ""
- prefix MxLx
- thumbs (~120) /default (1000) / max (~9000)
- All maps have year 0 => apply Chronoscope interval filter /fixed in v0.3
- 6 Maps adopted for Chronoscope, see buttons below
Pros
- still good performance of Chronoscope
- filter by year 0 hack >> should be a prefix/glam filter
- coordinate mistakes can easily be detected
Cons
- no unique IDs. why? /fixed in v0.3 initMapsDB
- duplicate previews. why?
- some quotes in title: LX100644430 > "
- no margin cropping
- /default/ (1000) maps are perceived low quality
- IDs vs. PPN:
- {"id":"Lx100638341","urlRef":"https://digitale-sammlungen.gwlb.de/resolve?PPN=100638406",…
{"id":"Lx100638341","urlRef":"https://digitale-sammlungen.gwlb.de/resolve?PPN=100638414",…
{"id":"Lx100638341","urlRef":"https://digitale-sammlungen.gwlb.de/resolve?PPN=100638376",…
