Andreas Lehmkühler commented on PDFBOX-4671:
--------------------------------------------
I've removed mostly all logs (info and error).
There is one warn message left in TextRegion#readAmountOfSymbolInstances
{code}
// sanity check: don't decode more than one symbol per pixel
long pixels = (long) regionInfo.getBitmapWidth() * (long)
regionInfo.getBitmapHeight();
if (pixels < amountOfSymbolInstances)
{
log.warn("Limiting number of decoded symbol instances to one per
pixel (" + pixels
+ " instead of " + amountOfSymbolInstances + ")");
amountOfSymbolInstances = pixels;
}
}
{code}
Should we keep that message and use the listener to provide it?
What about the removed error messages? I've simply removed them as those
"errors" never lead to an exception or something similar.
