<pre style="font-family:'Fira Code',monospace;font-size:13,5pt;">Hello,
I'm testing the new pluggable image API with SVG and noticed one thing.
Since SVG is a scalable vector format, it can be rendered at an arbitrary size.
For this purpose, we need to know the frame (pane) size and scale the image accordingly while rendering.
As I understand, ImageReadParam is used to pass the frame size to the image reader.
<font face="Fira Code, monospace">public class ImageReadParam extends IIOParam {
/**
* Returns {@code true} if this reader allows the source image to be rendered at an
* arbitrary size as part of the decoding process ...
*/
public boolean canSetSourceRenderSize() {
return canSetSourceRenderSize;
}
}</font>
But when I set canSetSourceRenderSize to true to activate this, I don't get the client frame size.
Instead, I get the actual image size, which the reader already knows since it implements the getWidth() and getHeight() methods.
I read the code and came across this:
<span style="color:#006dcc;"><a class="moz-txt-link-freetext" href="https://github.com/openjdk/jfx/blob/master/modules/javafx.graphics/src/main/java/com/sun/javafx/iio/java2d/J2DImageLoader.java#L122">https://github.com/openjdk/jfx/blob/master/modules/javafx.graphics/src/main/java/com/sun/javafx/iio/java2d/J2DImageLoader.java#L122</a>
</span><span style="color:#006dcc;">
</span>Why does the image loader use the reader's width and height in both branches?
Shouldn't the loader provide the frame size when canSetSourceRenderSize returns true?
Maybe I'm looking for something that isn't supported? Yet?
Best regards.</pre>
