<Swing Dev> [11][JDK-8195095]Images are not scaled correctly in JEditorPane

[Krishna Addepalli]

Hi Semyon,

 

To reduce the possibility of the test passing / failing due to wrong reasons, I have changed the color of the image to blue, and updated the test accordingly.

Here is the new webrev: http://cr.openjdk.java.net/~kaddepalli/8195095/webrev02

 

Thanks,

Krishna

I tried on Ubuntu 17.10, but since the getPixelColor always returns black, the test will pass, which is why I was asking.

 

Thanks,

Krishna

Hi Semyon,

 

Did you try it in Windows or Linux? I have tested it on Mac, and found that it fails before the fix and passes after the fix.

I tried it on Linux. But the change is in generic code why the test result depends on the platform?

Hi Krishna,

I tried your test before the fix and it passed.

looks good to me. 

Only thing, in test, JFrame creation also needs to be in EDT.

Hi All,

 

Please review a fix for JDK-8195095: https://bugs.openjdk.java.net/browse/JDK-8195095

 

Webrev: HYPERLINK "http://cr.openjdk.java.net/%7Ekaddepalli/8195095/webrev00"http://cr.openjdk.java.net/~kaddepalli/8195095/webrev00

 

Problem: When a text html is specified with an image, omitting either the height/width parameter, JEditorPane scales it to default value of the missing parameter, whereas it should fetch the actual value from the image.

 

Fix: The problem is in ImageView.java. In the imageUpdate function, in the resizing logic the "changed" flag is set to 1 if height is present, and to 2 if width is present. But while updating the width, the check is swapped, i.e width is set if flag is 1 and vice versa.

 

PS: The webrev contains a new "circle.png" file, so when you import the patch, you may need to manually copy the file, since "hg import" doesnot automatically import the .png files from the patch file.

 

Thanks

Krishna
