DotNet Core apps using libgdiplus do not appear antialiased on Mac. This occurs whether using Mono or CoreCompat System.Drawing.Image. Not entirely sure I'm aware of the internals; however, on Windows I believe this is using GDI+, whereas on Mac libgdiplus uses Cairo. On PC (left) the resized image is great, but aliased on Mac OS X (right) using the exact same code. Is there any insig
在Mac上,使用libgdiplus的DotNet Core应用程序不会显示反锯齿。 无论是使用Mono还是CoreCompat System.Drawing.Image,都会发生这种情况。 不完全确定我知道内部; 然而,在Windows上我相信这是使用GDI +,而在Mac上libgdiplus使用开罗。 在PC上(左图),调整后的图像很棒,但在Mac OS X(右侧)上使用完全相同的代码进行别名。 有没有任何见解如何解决macOS目标的这种不兼容问题? 用于调整图像大小的代码: using S
In my project, i need to help people to reduce the size of image. I have created an image resize method which work well for almost image format but not animated GIF!! Therefore, i want someone to help me to make it :) I have designed the process of how to resize an animated GIF: get the image in byte data=> split the frame of GIF to Image array => resize each Image of the array =
在我的项目中,我需要帮助人们缩小图像的大小。 我创建了一个图像调整大小的方法,几乎适用于图像格式,但不是动画GIF! 因此,我希望有人帮助我做到这一点:) 我设计了如何调整动画GIF的大小: 以字节数据=>获取图像 将GIF的帧分割为Image array => 调整数组的每个图像的大小=> 将这些图像合并为一个GIF图像=> 将GIF图像转换为字节数据=> 将字节数据上传到云 我不问这是什么代码,但问是否
I'm trying to add unit tests to the .Net ImageProcessor library: https://github.com/cosmo0/ImageProcessor/tree/tests I'm working on Xamarin/Mono on my Mac. Mono seems to have a few problems with animated gifs images. For my unit tests, I have a bunch of test images, and I load them all and run transformations on each of them. Each time I apply a filter (brightness for instance), it
我试图将单元测试添加到.Net ImageProcessor库中:https://github.com/cosmo0/ImageProcessor/tree/tests 我正在Mac上开发Xamarin / Mono。 单声道似乎有动画GIF图像的几个问题。 对于我的单元测试,我有一堆测试图像,我加载它们并在它们中的每一个上运行转换。 每次我应用滤镜(例如亮度)时,尝试重新创建图像时都会失败。 失败的行在这里:https://github.com/cosmo0/ImageProcessor/blob/tests/src/ImageProcesso
We load a C# project out of TFS, click on the solution and it builds fine on XP, but dies on Windows 7, with multiple Cannot write "C:...projectName.resources." Parameter is not valid. and one error that mentioned GDI+. Web searches turn up hits about constructing GIF objects in a program, but little about this problem except suggestions to replace all images with PNG's, with
我们从TFS中加载一个C#项目,点击解决方案,它在XP上构建得很好,但在Windows 7上死亡,并且有多个 无法写入“C:... projectName.resources”。 参数无效。 还有一个提到GDI +的错误。 网络搜索关于在程序中构建GIF对象的命中,但除了关于用PNG替换所有图像的建议,以及一些涉及Bitmap类中的Alpha通道问题的帖子,这个问题很少。 我为TIF尝试了这种方法,它使GDI错误消失,但一些图像是动画GIF,我们的用户接受了培训,
I have a javascript Windows 8 application, and I need to convert a bunch of canvases into an animated gif. Here's what I have so far: I can convert one canvas to a base64 encoded png like this (in javascript): var base64png = myCanvas.toDataURL() I can then convert this encoded image into an array of bytes (in ac# class library): private byte[] GetBytesFromBase64(string base64) {
我有一个JavaScript Windows 8应用程序,我需要将一堆画布转换为动画GIF。 这是我迄今为止的: 我可以将一个画布转换为base64编码的png,如下所示(在javascript中): var base64png = myCanvas.toDataURL() 然后,我可以将此编码图像转换为一个字节数组(在ac#类库中): private byte[] GetBytesFromBase64(string base64) { string data = base64.Split(',')[1]; // get everything after comma return Conv
I need to load GIF animations and convert them frame by frame to bitmaps. To do that, I am extracting my GIF file frame by frame using Drawing.Imaging library and then casting each frame to bitmap. Everything works just fine except the times when the consecutive frames are the same, when there is no pixel difference. The library seems to be dropping such frames. I came to that conslusion wi
我需要加载GIF动画并将它们逐帧转换为位图。 为此,我使用Drawing.Imaging库逐帧提取我的GIF文件,然后将每个帧转换为位图。 除了没有像素差异时连续帧相同的时候,一切都可以正常工作。 图书馆似乎正在放弃这样的框架。 我通过一个简单的测试来了这个混淆。 我创建了一个圆圈的动画,在最后一个圆圈消失和新的圆圈尚未显示的那一刻之间停顿一段时间后,这个圆圈正在增长并缩小。 当我播放由我提取的位图组成的动画时,
I have some SQL from our DBA which I'm just checking it is right, since the EF doesn't seem to fully link entities together. It knows there is a relation but doesn't perform the FK to PK link. Any ideas or thoughts (rather than use NHibernate! ) on it are appreciated. 1 CREATE TABLE [dbo].[Employee]( 2 [ID] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL, 3 [Per
我从我们的DBA中获得了一些SQL,我只是检查它是正确的,因为EF似乎没有将实体完全链接在一起。 它知道有一个关系,但不执行PK链接的FK。 任何想法或想法(而不是使用NHibernate!)都很赞赏。 1 CREATE TABLE [dbo].[Employee]( 2 [ID] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL, 3 [PersonID] [int] NOT NULL, 4 [GenderID] [int] NULL, 5 [EthnicOriginID] [int] NULL, 6

I'm looking for a way of passing additional information to a TypeConverter in order to provide some context for conversions without creating a custom constructor. That extra information passed would be original object (known at compile time as an interface) that contains the property that I am converting. It contains properties of its own like Id that are useful for lookups to convert rela
我正在寻找一种将附加信息传递给TypeConverter ,以便在不创建自定义构造函数的情况下为转换提供一些上下文。 传递的额外信息将是原始对象(在编译时已知为接口),其中包含我正在转换的属性。 它包含像Id一样的属性,对于查找转换相关信息非常有用。 我查看了ITypeDescriptorContext的文档,但是我没有找到如何实现该界面的清晰示例。 我也不相信这是我需要的工具。 目前,在我的代码中,我打电话给: // For each writ
