      + +## dbr-6.3.0.1 comparison between two builds + +In version 6.3.0.1, our team compiled the C++ module of Dynamsoft Barcode Reader to WebAssembly, so that users can scan barcode with JavaScript at client-side. The new JavaScript edition is not matured, in that we are still juggling between speed and stability. Currently we are releasing it as a preview, with two builds. + +Here is a comparison chart between the two: + +| |dbr-6.3.0.1 |dbr-6.3.0.1.mobile | +|- |- |- | +|arguments for compiling to .wasm |allowed C++ try-catch |disable C++ try-catch | +|size of .wasm |5.47M |4.02M | +|download at initial visit1 |depends on network |depends on network | +|browser compile speed2 |slow |quick | +|memory needed during compiling |large |medium | +|exceptions during reading |really few |medium | +|memory leak3 |almost no memory leak |possible | +|decode success rate |high |medium | +|decode upload image |suitable |not suitable | +|one-off decoding in a video stream |suitable |suitable | +|continuous scan in a video stream |suitable |not suitable | + +Note: + +1. Users only need to download the `.wasm` files at their first visit. +2. With Firefox and Edge, the browser supports caching compiled WebAssembly modules to `IndexedDB`, which allows users to store structured data on the client-side. So, from the second visit forward, the browser can finish page loading in a split second by retrieving the module file.
      + Chrome and Safari do not support the aforementioned caching mechanism. We can store the `.wasm` file to `IndexedDB`, but not the compiled module file. So compilation is required at every visit. +3. The mobile version skipped compilation of `try...catch` in C++ code, so some exceptions failed to be caught, resulting in possible memory leaks. When the memory leaks to a certain extent, the barcode scanning module will stop working due to insufficient memory. The leaked memory can be released when leaving or refreshing the web page. Therefore, the mobile version is not suitable for continuous decoding, but it can be used for one-off decoding. + +In the next step, we will reduce the dependency on try...catch in C++ so as to combine the two versions into one, and work out a version that is fast to load and has a stable decoding capability. diff --git a/examples/helloworld/helloworld.html b/examples/decodeFileInMemory/decodeFileInMemory.html similarity index 100% rename from examples/helloworld/helloworld.html rename to examples/decodeFileInMemory/decodeFileInMemory.html diff --git a/examples/video/decodeVideo.html b/examples/decodeVideo/decodeVideo.html similarity index 100% rename from examples/video/decodeVideo.html rename to examples/decodeVideo/decodeVideo.html diff --git a/examples/video/js/decodeVideo.js b/examples/decodeVideo/js/decodeVideo.js similarity index 100% rename from examples/video/js/decodeVideo.js rename to examples/decodeVideo/js/decodeVideo.js diff --git a/examples/videoInWorker/decodeVideoInWorker.html b/examples/decodeVideoInWorker/decodeVideoInWorker.html similarity index 100% rename from examples/videoInWorker/decodeVideoInWorker.html rename to examples/decodeVideoInWorker/decodeVideoInWorker.html diff --git a/examples/videoInWorker/js/decodeVideoInWorker.js b/examples/decodeVideoInWorker/js/decodeVideoInWorker.js similarity index 100% rename from examples/videoInWorker/js/decodeVideoInWorker.js rename to examples/decodeVideoInWorker/js/decodeVideoInWorker.js diff --git a/examples/barcode-scanner/barcode_reader_javascript.html b/examples/decodeVideoWithSettings/barcode_reader_javascript.html similarity index 100% rename from examples/barcode-scanner/barcode_reader_javascript.html rename to examples/decodeVideoWithSettings/barcode_reader_javascript.html diff --git a/examples/barcode-scanner/css/foundation.min.css b/examples/decodeVideoWithSettings/css/foundation.min.css similarity index 100% rename from examples/barcode-scanner/css/foundation.min.css rename to examples/decodeVideoWithSettings/css/foundation.min.css diff --git a/examples/barcode-scanner/css/style.css b/examples/decodeVideoWithSettings/css/style.css similarity index 100% rename from examples/barcode-scanner/css/style.css rename to examples/decodeVideoWithSettings/css/style.css diff --git a/examples/barcode-scanner/js/foundation.min.js b/examples/decodeVideoWithSettings/js/foundation.min.js similarity index 100% rename from examples/barcode-scanner/js/foundation.min.js rename to examples/decodeVideoWithSettings/js/foundation.min.js diff --git a/examples/barcode-scanner/js/script.js b/examples/decodeVideoWithSettings/js/script.js similarity index 100% rename from examples/barcode-scanner/js/script.js rename to examples/decodeVideoWithSettings/js/script.js diff --git a/examples/barcode-scanner/js/what-input.min.js b/examples/decodeVideoWithSettings/js/what-input.min.js similarity index 100% rename from examples/barcode-scanner/js/what-input.min.js rename to examples/decodeVideoWithSettings/js/what-input.min.js From 54f10957ccbd2e73233e03325cd766a15a30ca03 Mon Sep 17 00:00:00 2001 From: Keillion <735699921@qq.com> Date: Wed, 5 Sep 2018 00:07:27 +0800 Subject: [PATCH 021/168] guide api md --- README.md | 2 ++ 1 file changed, 2 insertions(+) diff --git a/README.md b/README.md index 15a8e74a..847527cb 100644 --- a/README.md +++ b/README.md @@ -14,6 +14,8 @@ Get the [trial license](https://www.dynamsoft.com/CustomerPortal/Portal/Triallic https://demo.dynamsoft.com/dbr_wasm/barcode_reader_javascript.html ## API Documentation +[guide.md](documents/guide.md) +[api.md](documents/api.md) https://www.dynamsoft.com/help/Barcode-Reader-wasm/index.html ## HowTo From 9bbcddb7408b4419eaefa5a7228b5327a92f3352 Mon Sep 17 00:00:00 2001 From: Keillion <735699921@qq.com> Date: Wed, 5 Sep 2018 08:57:10 +0800 Subject: [PATCH 022/168] more space --- README.md | 3 +++ 1 file changed, 3 insertions(+) diff --git a/README.md b/README.md index 847527cb..304dba1c 100644 --- a/README.md +++ b/README.md @@ -14,8 +14,11 @@ Get the [trial license](https://www.dynamsoft.com/CustomerPortal/Portal/Triallic https://demo.dynamsoft.com/dbr_wasm/barcode_reader_javascript.html ## API Documentation + [guide.md](documents/guide.md) + [api.md](documents/api.md) + https://www.dynamsoft.com/help/Barcode-Reader-wasm/index.html ## HowTo From 4494988cda9b955549af6a199b029d90820ae79f Mon Sep 17 00:00:00 2001 From: Keillion <735699921@qq.com> Date: Wed, 5 Sep 2018 10:34:43 +0800 Subject: [PATCH 023/168] some statement --- documents/api.md | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/documents/api.md b/documents/api.md index 3508c15b..4ec536ff 100644 --- a/documents/api.md +++ b/documents/api.md @@ -42,12 +42,12 @@ dynamsoft.dbrEnv.licenseKey = "", dynamsoft.dbrEnv.bAutoLoadWasm = true;

With Firefox and Edge, the browser supports caching compiled WebAssembly modules to `IndexedDB`, which allows users to store structured data on the client-side. So, from the second visit forward, the browser can finish page loading in a split second by retrieving the module file.
      - Chrome and Safari do not support the aforementioned caching mechanism. We can store the `.wasm` file to `IndexedDB`, but not the compiled module file. So compilation is required at every visit. -3. The mobile version skipped compilation of `try...catch` in C++ code, so some exceptions failed to be caught, resulting in possible memory leaks. When the memory leaks to a certain extent, the barcode scanning module will stop working due to insufficient memory. The leaked memory can be released when leaving or refreshing the web page. Therefore, the mobile version is not suitable for continuous decoding, but it can be used for one-off decoding. - -In the next step, we will reduce the dependency on try...catch in C++ so as to combine the two versions into one, and work out a version that is fast to load and has a stable decoding capability. +Try to write your own page.

      + +## Load + +Put `dbr-.min.js` and `dbr-.wasm` in the same directory as your html page.

      + +``` + +You can now open the page and run it. It will take a long time to load the page for the first time. Because `dbr-.min.js` will execute to download the whole `dbr-.wasm` file and compile it. Please wait patiently for the loading to finish. + +After loading successfully, if the browser supports [IndexedDB](https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API), we will try to store the compiled result of `dbr-.wasm` or the file itself in the browser cache locally. The workflow is as below. + +First we will try to store the compiled result of the `WebAssembly.Module` type (currently only supported in FireFox and Edge, and other browsers will probably also add this feature in the future). The next time the page is loaded, it can be completed within seconds. + +If the browsers don't support it, we will save the `dbr-.wasm` file itself. It will take some time to compile when initializing next time. At least there is no need to download it again. + +

      + +## dbr-6.3.0.1 comparison between two builds + +In version 6.3.0.1, our team compiled the C++ module of Dynamsoft Barcode Reader to WebAssembly, so that users can scan barcode with JavaScript at client-side. The new JavaScript edition is not matured, in that we are still juggling between speed and stability. Currently we are releasing it as a preview, with two builds. + +Here is a comparison chart between the two: + +| |dbr-6.3.0.1 |dbr-6.3.0.1.mobile | +|- |- |- | +|arguments for compiling to .wasm |allowed C++ try-catch |disable C++ try-catch | +|size of .wasm |5.47M |4.02M | +|download at initial visit1 |depends on network |depends on network | +|browser compile speed2 |slow |quick | +|memory needed during compiling |large |medium | +|exceptions during reading |really few |medium | +|memory leak3 |almost no memory leak |possible | +|decode success rate |high |medium | +|decode upload image |suitable |not suitable | +|one-off decoding in a video stream |suitable |suitable | +|continuous scan in a video stream |suitable |not suitable | + +Note: + +1. Users only need to download the `.wasm` files at their first visit. +2. With Firefox and Edge, the browser supports caching compiled WebAssembly modules to `IndexedDB`, which allows users to store structured data on the client-side. So, from the second visit forward, the browser can finish page loading in a split second by retrieving the module file.
      + Chrome and Safari do not support the aforementioned caching mechanism. We can store the `.wasm` file to `IndexedDB`, but not the compiled module file. So compilation is required at every visit. +3. The mobile version skipped compilation of `try...catch` in C++ code, so some exceptions failed to be caught, resulting in possible memory leaks. When the memory leaks to a certain extent, the barcode scanning module will stop working due to insufficient memory. The leaked memory can be released when leaving or refreshing the web page. Therefore, the mobile version is not suitable for continuous decoding, but it can be used for one-off decoding. + +In the next step, we will reduce the dependency on try...catch in C++ so as to combine the two versions into one, and work out a version that is fast to load and has a stable decoding capability.
