Not scaling svg in Image

[Mihaill]

@odelaune It's not widgets. I use QML image and set source.

Image {
            id: imageMap
            source: "/path/to/file/or/data/from/file"
            anchors.verticalCenter: parent.verticalCenter
            anchors.horizontalCenter: parent.horizontalCenter
            width: flickableMap.contentWidth * 0.2
            height: flickableMap.contentHeight * 0.2
            fillMode: Image.PreserveAspectFit

@Mihaill can you show your pic? If it is too complicated, svg may not be able to keep the resolution.

@JoeCFD I cant load heare svg file. All vector graphics are scaled.

@Mihaill
There are two notable reasons why you may not choose to use an SVG file.
1. Not the right format for high-quality or detailed photos. Designers create vector graphics with points and paths, not pixels. ...
2. Requires some knowledge of code. SVG is an XML-based scene description language for graphics.

I have a background image with a lot of machines and svg does not help in its display. Therefore, it was made to png.

@JoeCFD With my svg file all good, I can scaled his in Inkscape. What me need doing with my svg? Me need scaled image.

I am not an expert in QML as I am always using QWidgets. Inside QWidgets you would use something like QPixmap or QImage. Both render the SVG file with a certain resolution and forget about the source. This is why it would also look pixelated using QWidgets. There, I would write code that reacts to the scaling and reloads the SVG every time to have the proper size (maybe a trick would be to load it with twice the pixelRatio and hope it looks fine when scaled like this).

I am not sure how (or if) this approach translates to QML. Can you react to the resizing in QML and then "change" the image to the same SVG file?

@SimonSchroeder updating image not help me, Image rendered svg with big pixels.

@Mihaill set the Image mipmap property to true

mipmap: true

@johngod It's too not help me. Scaled image are blurred.

@JoeCFD Thanks, it is help me

sourceSize.width: paintedWidth
sourceSize.height: paintedHeight
