Hello,
we have a problem with displaying images in the PictureBox.
Within the designer, all images are displayed in good quality.
Also in the preview of the report in Visual Studio, all images are displayed in good quality.
If we start the application and display the report via the report viewer, all images are displayed in a poorer quality.
What could be the problem?

Hi Michael,
The quality of the images in PictureBox item is mostly decreased when a scaling is applied. The renderer does not apply antialiasing or any other bitmap scaling mode when drawing the PictureBox's contents, because it would slow down the rendering process. So when drawing images, we use the default scaling mode (Linear), which provides the fastest processing.
Based on users demand, we will introduce a Device Information setting that will allow the user to control the bitmap scaling mode when rendering in WPFXAML and WPFXAMLInteractive formats. Once it passes the testing stage, this improvement will be included in a subsequent release of our product.

Hello,
Is it implemented now ?
I'm displaying a SVG logo in the report. But in the WPF reportViewer, the image is in bad quality.
How can I fix it ?

Hi Gabriel,
The PictureBox works with SVG images, so it is not expected to see the picture with bad quality. Do you have any settingd of the rendering in the app.config file?
