Radu Coravu created FOP-2369:
--------------------------------
Summary: Call "javax.imageio.ImageReader.canReadRaster()" before
attempt to read raster
Key: FOP-2369
URL: https://issues.apache.org/jira/browse/FOP-2369
Project: Fop
Issue Type: Bug
Components: images
Affects Versions: 1.1
Reporter: Radu Coravu
The method:
org.apache.xmlgraphics.image.loader.impl.imageio.ImageLoaderImageIO.getFallbackBufferedImage(ImageReader,
int, ImageReadParam)
calls:
reader.readRaster(pageIndex, param);
but it should first call "javax.imageio.ImageReader.canReadRaster()" to see if
the reader can render the raster.
Otherwise if the image reader cannot render rasters such exceptions may occur:
