- Implemented `build_mesh_plane.py` to create a geometry node group for mesh planes with customizable parameters. - Created `build_shadeless.py` for a shader node group that displays color without scene lighting while preserving shadows and reflections. - Added `validate.py` to validate the integrity of the newly created node groups and their inputs. - Introduced `validate_cutout.py` to ensure the functionality of cutout node groups and their dependencies. - Developed `validate_mesh_plane.py` to test the mesh plane creation and its modifier settings.

Upscale
本页对应 src/anyimage/operators/upscale.py。该模块读取扩展首选项中的模型与全局 AI 输入长边上限,提交 4× 高清任务,并维护高清结果到原始 Image 的引用。

模型以 256×256 分块处理 RGB,并带入相邻上下文以减弱块边界;Alpha 按同一受限输入尺寸单独缩放,最后合并为 RGBA。max_input_size 来自全局 Maximum AI Input Size,默认 2048,只约束送入模型的长边;4× 输出长边因此默认为最多 8192。输入尺寸不超过上限时不会发生预缩放。
结果以 _upscale.png 结尾,并通过 Image.anyimage_upscale_source 保存原图引用。再次对高清结果执行时,Operator 会从原图重新生成,而不是继续放大上一次输出。模型与全局输入上限在每次执行时从 Preferences 读取,再写入可序列化的隐藏属性交给 Job。Provider 资源错误会释放当前 Upscale Session,并提示降低全局输入上限或改用 CPU。
