[jira] [Commented] (BATIK-1150) ArrayIndexOutOfBoundsException when referencing PNG with 8-bit color

["Radu Coravu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BATIK-1150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15288553#comment-15288553 ] 

Radu Coravu commented on BATIK-1150:
------------------------------------

The problem is that the PNG has only one band and the GraphicsUtil tries to copy pixels from an image with one band to an image with 3 bands.

As a possible suggested fix on the method:

org.apache.batik.ext.awt.image.rendered.Any2sRGBRed.copyData(WritableRaster)

at some point there is a comparison like:

{code}if (srcCM.getColorSpace() == dstCM.getColorSpace()){
///Calls the GraphicsUtil part
}
{code}

which could be rewritten like:

{code} if (srcCM.getColorSpace() == dstCM.getColorSpace()
             // If the number of bands do not match, also perform forced conversion...
            && srcSM.getNumBands() == wr.getNumBands()) {
.....
{code}
