com.intellij.ui.svg.loadSvg replacement

What is the correct alternative for “com.intellij.ui.svg.loadSvg()”?

Code:

val url = URI.create(iconUrl).toURL()
val svgContent = url.readText()
val bufferedImage: BufferedImage = loadSvg(
    data = svgContent.byteInputStream().readBytes(),
    scale = scale.toFloat(),
)
val loadedIcon = ImageIcon(bufferedImage)

Requirement:
Using an SVG URL, I need to get a scaled version of it to render it in the UI.

SVGLoader is also internal.
Suggested alternatives like ImageLoader, IconLoader do not scale as expected for SVGs.

We use JSVG under the hood, maybe you can use it directly?

Hi @yuriy.artamonov ,
Are you referring to this one?
‘com.intellij.ui.svg.JSvgDocument.Companion’ is declared in unstable ‘com.intellij.ui.svg.JSvgDocument’ marked with @ApiStatus.Internal.

No, to original JSVG library

JetBrains is using a forked version of JSVG. Unfortunately, some useful APIs are private in this version (I don’t know why).
Consider using the original JSVG: GitHub - weisJ/jsvg: Java SVG renderer. Its APIs are more open.
If you want to stick to the JetBrains’ fork, you can scale your imagesby using ImageUtil.scaleImage. This is what I’m doing in a plugin. I found no workaround to load an image from bytes, so I load images from files directly (file://) or from resources.

Able to get the required scaling with the original JSVG library.
Thank You!

Didn’t try, but IconLoader.findIcon(url) should be the right way.

@m.sciachero ,
Unfortunately, that doesn’t work as expected for me.
