What is the best way to load a byte[] (which is a jpeg file) in the ImageEditor.
Ideally I want to transform the byte[] to a Bitmap (easy), for storage purpose
using Stream stream = new MemoryStream(e.Buffer);
using Bitmap image = new Bitmap(stream);
And then display the bitmap, but I don't know how totransform it to an ImageSource.
Regards.
Is there a way to retrieve a pixel of the image in the imageEditor when clicking on it
I could implement something working well , but not when the image is zoomed or moved in the editor
public static Point Calc_Coordinates(double w_image, double h_image, double w_container, double h_container, double click_x, double click_y){
Double zoomW = (w_container / w_image);
Double zoomH = (h_container / h_image);
Double zoomActual = Math.Min(zoomW, zoomH);
Double padX = zoomActual == zoomW ? 0 : (w_container - (zoomActual * w_image)) / 2;
Double padY = zoomActual == zoomH ? 0 : (h_container - (zoomActual * h_image)) / 2;
Point res = new Point();
res.X = (Int32)((click_x - padX) / zoomActual);
res.Y = (Int32)((click_y - padY) / zoomActual);
//
if (res.X < 0 || res.X > w_image) { res.X = -1};
if (res.Y < 0 || res.Y > h_image) { res.Y = -1};
return res;
}
Desired: Sample self-contained Maui or Maui/Blazor Reporting solution.
Background:
My Maui/Blazor app currently uses another vendor's Blazor Report Viewing tool, but that only compiles in Android and Windows. Viewer and Designer run in the same project and do not require a remote service.
Reports were previously designed in a WPF project using same vendor, but he says he has no plans to fully support Blazor use in Maui.
As I already have access to Telerik reporting, I would love to upgrade and view my reports using your Reporting, but I have yet to locate any Maui-specific instructions. Report Viewing should work without requiring any service outside the solution.
Is it possible to use GestureRecognizers in ImageEditor ? I tried this, but OnImageTapped is not called.
<?xml version="1.0" encoding="utf-8" ?>
<ContentView xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"
xmlns:versares="clr-namespace:SharedResources;assembly=SharedResources"
x:Class="PalletGate.Views.SingleEditor">
<Grid ColumnDefinitions="*">
<telerik:RadImageEditor x:Name="imageEditor1"
MinZoomLevel="0.1"
MaxZoomLevel="20"
Grid.Column="0"
>
<telerik:RadImageEditor.GestureRecognizers>
<TapGestureRecognizer Tapped="OnImageTapped" />
</telerik:RadImageEditor.GestureRecognizers>
</telerik:RadImageEditor>
</Grid>
</ContentView>
Code behind :
private void OnImageTapped(object sender, TappedEventArgs e) {Point? position = e.GetPosition((Element)sender);
Telerik.Maui.Controls.RadImageEditor? img = sender as Telerik.Maui.Controls.RadImageEditor;
}
Hi Team,
I would like to be able to have client-side filtering/sorting/grouping capabilities for large backend datasets that cannot be entirely loaded on the client.
As it stands now, the DataGrid (and other data components) can only operate on the data that is has in the local DataView. This means that I need to build a custom filtering solution that prefilters/presorts the backend data before paging and loading it into the DataGrid.
To accomplish the "full view", we need a data layer that understands both the UI as well as the backend. The Telerik UI for WPF product has an excellent solution for this, known as the WPF EntityFrameworkCoreDataSource - Overview - Telerik UI for WPF and the WPF DataServiceDataSource - Overview - Telerik UI for WPF.
If such a feature can be added to Telerik UI for MAUI, it would be an excellent bonus for the component suite in data heavy applications.
Thank you,
Peter
