IplImage.create error: java.awt.image.SinglePixelPackedSampleModel cannot be cast to java.awt.image.ComponentSampleModel #102

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Obtain a bufferedimage with SinglePixelPackedSampleModel, such as one 
obtained via Robot.captureScreen
2. Try to convert this bufferedimage to IplImage using IplImage.create

What is the expected output? What do you see instead?
Should not have any error. It was working fine before in 0705 version. But it 
is now throwing typecast error at (opencv_core.java:860)

What version of the product are you using? On what operating system?
0820, all operating system

Please provide any additional information below.
860: pixelSize = ((ComponentSampleModel)sm).getPixelStride();
should probably be replaced with pixelSize=1

Nevermind... I just updated the svn version and it seems to work! Thanks!
