Hi Mohammed, I see the problem with the tempView_Hide.png, when running the OSG with OSG_NOTIFY_LEVEL set to DEBUG the ong plugin outputs the message:
width=300 height=298 depth=8 color == PNG_COLOR_TYPE_GRAY I checked the plugin and it does have code hadnling PNG_COLOR_TYPE_GRAY so I would have expected it to be a supported type. I'm not the author of the plugin so really just in the same position as you as to how to go about debugging it further. It could be a bug in libpng, or it could be a bug in the OSG's handling of this specific variant of the png format. The best I can recommend is working through the png plugin to see how it's converting the data to see it's making an error somewhere. Robert.
