…a bunch of (randomly) ordered parameters Given the number of existing parameters, this will avoid needlessly unwieldy call-sites especially with upcoming changes in later patches.
…n the image one (PR 12001 follow-up) This will allow caching of ColorSpaces by either `Name` *or* `Ref`, which doesn't really make sense for images, thus allowing (better) caching for ColorSpaces used with e.g. Images and Patterns.
This patch contains the following *notable* improvements: - Changes the `ColorSpace.parse` call-sites to, where possible, pass in a reference rather than actual ColorSpace data (necessary for the next point). - Adds (local) caching of `ColorSpace`s by `Ref`, when applicable, in addition the caching by name. This (generally) improves `ColorSpace` caching for e.g. the SMask code-paths. - Extends the (local) `ColorSpace` caching to also apply when handling Images and Patterns, thus further reducing unneeded re-parsing. - Adds a new `ColorSpace.parseAsync` method, almost identical to the existing `ColorSpace.parse` one, but returning a Promise instead (this simplifies some code in the `PartialEvaluator`).
…ntry of `ICCBased` ColorSpaces (PR 9659 follow-up) With the changes made in PR 9659, `ColorSpace.fromIR` no longer takes a second `pdfFunctionFactory` parameter and there's thus one call-site that can be simplified.

As always, thanks for landing the PR! (I'm currently looking into caching of parsed Functions, which may further improve some documents.) |
This patch contains the following notable improvements:
ColorSpace.parsecall-sites to, where possible, pass in a reference rather than actual ColorSpace data (necessary for the next point).ColorSpaces byRef, when applicable, in addition the caching by name. This (generally) improvesColorSpacecaching for e.g. the SMask code-paths.ColorSpacecaching to also apply when handling Images and Patterns, thus further reducing unneeded re-parsing.ColorSpace.parseAsyncmethod, almost identical to the existingColorSpace.parseone, but returning a Promise instead (this simplifies some code in thePartialEvaluator).
