Next.js rewrites `/api` to `http://localhost:8888` The canvas asset picker and drag-and-drop surface accept DWG and DXF files up to 24 MB. Conversion runs locally in a browser worker, uploads a sanitized derived SVG, and leaves the source file unchanged. DXF supports ASCII and binary drawings; DWG supports AutoCAD R14 through AutoCAD 2018 format families. +Derived CAD SVGs retain bounded semantic metadata for drawing units, layers, reusable blocks, entity types, visible labels, and crop-indexed bounds. Agent Chat sends this metadata as hidden reference context while rasterizing only the model-bound image input to transparent WebP. Vector crop keeps the original SVG and creates a smaller transparent WebP sibling beside it with crop-specific semantic context, ready for follow-up questions in Agent Chat. + ## Cache Config Default in-memory cache: diff --git a/frontend/src/domain/design.ts b/frontend/src/domain/design.ts index 61698b7..14181dc 100644 --- a/frontend/src/domain/design.ts +++ b/frontend/src/domain/design.ts @@ -19,6 +19,7 @@ export type CanvasNode = { status: string; parentId?: string; layerRole?: string; + semanticContext?: string; fontSize?: number; fontFamily?: string; fontWeight?: string; diff --git a/frontend/src/i18n/locales/en-US.json b/frontend/src/i18n/locales/en-US.json index ddf1a62..ebd3fe2 100644 --- a/frontend/src/i18n/locales/en-US.json +++ b/frontend/src/i18n/locales/en-US.json @@ -583,6 +583,8 @@ "adjustImage": "Adjust", "adjustPrompt": "Apply the adjustment parameters to improve light, color, contrast, and detail; if no values are set, automatically improve the overall look while preserving subject and composition.", "cropImage": "Crop", + "cropResultTitle": "{title} crop", + "cropCreated": "Created a cropped image beside the source", "cropPrompt": "Recompose the image using the selected crop region and keep the important frame.", "cropPresets": "Presets", "cropPresetGeneral": "General", diff --git a/frontend/src/i18n/locales/zh-CN.json b/frontend/src/i18n/locales/zh-CN.json index e3d97ce..004db82 100644 --- a/frontend/src/i18n/locales/zh-CN.json +++ b/frontend/src/i18n/locales/zh-CN.json @@ -583,6 +583,8 @@ "adjustImage": "调整", "adjustPrompt": "根据调整参数优化图片光线、色彩、对比度和细节；如果没有指定数值，则自动优化整体观感，同时保持主体与构图不变。", "cropImage": "裁剪", + "cropResultTitle": "{title} 裁剪区域", + "cropCreated": "已在原图右侧创建裁剪图", "cropPrompt": "按用户选择的裁剪区域重构图片构图，只保留关键画面。", "cropPresets": "预设", "cropPresetGeneral": "通用", diff --git a/frontend/src/infrastructure/designGateway/canvasSnapshot.ts b/frontend/src/infrastructure/designGateway/canvasSnapshot.ts index f3e443a..47f77d4 100644 --- a/frontend/src/infrastructure/designGateway/canvasSnapshot.ts +++ b/frontend/src/infrastructure/designGateway/canvasSnapshot.ts @@ -170,6 +170,7 @@ function normalizeCanvasNode(node: Partial | null | undefined, index status: stringValue(fieldValue(source, "status", "Status")) || "success", parentId: stringValue(fieldValue(source, "parentId", "ParentID")) || undefined, layerRole: stringValue(fieldValue(source, "layerRole", "LayerRole")) || undefined, + semanticContext: stringValue(fieldValue(source, "semanticContext", "SemanticContext")) || undefined, fontSize: optionalNumberValue(fieldValue(source, "fontSize", "FontSize")), fontFamily: stringValue(fieldValue(source, "fontFamily", "FontFamily")) || undefined, fontWeight: stringValue(fieldValue(source, "fontWeight", "FontWeight")) || undefined, diff --git a/frontend/src/ui/components/ImageNodeActions/index.tsx b/frontend/src/ui/components/ImageNodeActions/index.tsx index 71d6964..1c7f8ab 100644 --- a/frontend/src/ui/components/ImageNodeActions/index.tsx +++ b/frontend/src/ui/components/ImageNodeActions/index.tsx @@ -47,6 +47,7 @@ import { useI18n } from "@/i18n/i18n"; import { useFloatingToolbarPlacement } from "@/ui/hooks/useFloatingToolbarPlacement"; import { CanvasColorPopover } from "@/ui/pages/CanvasWorkspace/canvas/CanvasColorPopover"; import { clamp } from "@/ui/pages/CanvasWorkspace/canvas/canvasGeometry"; +import { cropSelectionScreenBounds } from "@/ui/pages/CanvasWorkspace/canvas/cropViewport"; import { ToolbarCustomizeDialog, ToolbarCustomizeMenuButton, type ToolbarCustomizeItem } from "@/ui/components/ToolbarCustomizeDialog"; import type { ImageAdjustments } from "@/ui/lib/imageAdjustments"; import type { NodeScreenBounds } from "@/ui/pages/CanvasWorkspace/canvas/types"; @@ -548,10 +549,12 @@ export function ImageNodeToolbar({ export function VectorizedImageToolbar({ bounds, leftInset, + onCrop, onDownload }: { bounds: NodeScreenBounds; leftInset?: number; + onCrop: () => void; onDownload: () => void; }) { const { t } = useI18n(); @@ -569,6 +572,9 @@ export function VectorizedImageToolbar({ {t("vector")} + @@ -1514,6 +1520,7 @@ export function CropOverlay({ } | null>(null); const cropSize = normalizeCropSourceSize(sourceSize, bounds); const activeSelection = clampCropRect(selection ?? fullCropSelection); + const activeSelectionBounds = cropSelectionScreenBounds(bounds, activeSelection); const selectionWidth = Math.round(activeSelection.width * cropSize.width); const selectionHeight = Math.round(activeSelection.height * cropSize.height); const currentAspectRatio = cropSelectionAspectRatio(activeSelection, cropSize); @@ -1578,7 +1585,7 @@ export function CropOverlay({ return ( <> -
