SwiftUI masking gradient with UIImage

Asked 2022-Jan-20 at 06:27

I want to mask a linear gradient with a Image initialized with Image(uiImage: ...). This kind of masking can clearly be done with Images initialized as systemName but when done with a UIImage there is no "masking" performed. Note that I need to use UIImage because my intention is to use a generated qrcode as the mask.

The generated qrCodeImage has no transparency (as you expected) but black& white, so it is just needed to convert it additionally into mask.

Firt thing, this is not the case like in this link

Since all images (including PNG) are displayed normally except the one generated dinamically by a Spring mapping.

So, that said, I have the following situation. I have a controller with this mapping:

Turned out to be a security issue. From brower I have access but only because I'm logged in. If I try to get the image without being logged in, a security error poped up.

So solution is to play around with the controller pattern and security:http intercept-url

The following shows how to create a PDF document that has one QR code per page using NuGet packages iTextSharp and QRCoder. Most of the code is from the OP, however it needed to be rearranged. I added code to allow the size of the QR code to be specified. The code used for testing is included.

The following assumes that you're using a VB.NET ASP.NET Web Application (.NET Framework) project. For testing, I used the Empty project template. Under "Add folders & core references", I checked Web Forms. Under "Advanced", I unchecked Configure for HTTPS.

Open Solution Explorer

In VS menu, click View
Select Solution Explorer

Download/install NuGet packages:

In Solution Explorer, right-click
Select Manage NuGet Packages...
Click Browse
Search: QRCoder
Select desired version (ex: 1.4.1)
Click Install
Search: iTextSharp
Select desired version (ex: 5.5.13.2)
Click Install

Add Webform (name: default.aspx)

In VS menu, click Project
Select Add New Item...
Select Web Form (name: default.aspx)
Click Add

The base64 value you provided in your question is malformed, my recommendation is to not use Json Serialization for this Api response effort.

Try using Convert.ToBase64String

Ensure the method returns string
and the jQuery request accepts/expects text for dataType response.

Does support the framework.net 3.5 default value in the method

The .NET Framework supports optional parameters in version 3.5 (in terms of the attributes being part of the framework), but the C# 3 compiler (which is what Visual Studio 2008 uses) doesn't. Optional parameters and named arguments were introduced in C# 4.

I would strongly recommend using a modern version of Visual Studio, even if you still need to target ancient versions of .NET. (I'd also strongly recommend moving off unsupported versions of .NET if at all possible.)
