From 5ad21ee097a2049e96d502e0b3735bbe1d3fee9c Mon Sep 17 00:00:00 2001 From: hailin Date: Sat, 3 Jan 2026 23:22:16 -0800 Subject: [PATCH] fix(mobile-app): adjust signature image ratio to match PDF field MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The signature image was 600x200 (3:1 ratio) but the PDF signature field is 92x51 (1.8:1 ratio). This caused the signature to be scaled down to only 60% of the field height, making it appear too small. Changed signature image dimensions to 460x255 (~1.8:1) to better match the PDF field proportions and maximize signature size. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- .../presentation/widgets/signature_pad.dart | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/frontend/mobile-app/lib/features/contract_signing/presentation/widgets/signature_pad.dart b/frontend/mobile-app/lib/features/contract_signing/presentation/widgets/signature_pad.dart index a033c17a..2624d9dd 100644 --- a/frontend/mobile-app/lib/features/contract_signing/presentation/widgets/signature_pad.dart +++ b/frontend/mobile-app/lib/features/contract_signing/presentation/widgets/signature_pad.dart @@ -162,8 +162,10 @@ class _SignaturePadState extends State { Future _renderSignatureImage() async { try { // 创建画布 - const width = 600.0; - const height = 200.0; + // 尺寸比例需要匹配PDF签名字段比例（约92:51 ≈ 1.8:1） + // 使用较大尺寸保证清晰度 + const width = 460.0; + const height = 255.0; final recorder = ui.PictureRecorder(); final canvas = Canvas(recorder, Rect.fromLTWH(0, 0, width, height));
