Confirmed that none of the PNG files exhibit the XMP-after-IDAT problem:Įxiftool -api pngearlyxmp -a -warning scan01-macpreview.pngĮxiftool -api pngearlyxmp -a -warning scan01-magick.pngĮxiftool -api pngearlyxmp -a -warning scan01-macpreview+exiftool.pngĮxiftool -api pngearlyxmp -a -warning scan01-magick+exiftool.pngĬonclusion: ImageMagick is doing something funky to PNG metadata so that Mac utilities can't see the metadata. Expose tags inside the tagged files:Įxiftool -a -G1 -s scan01-magick+exiftool.png > scan01-magick+Įxiftool -a -G1 -s scan01-macpreview+exiftool.png > scan01-macpreview+īoth files show equivalent time & place tags, but at different places in the files:Ĭode Select Expand CreateDate : 1995:02:06 09:09:09 scan01-macpreview+exiftool.png - tagged time & place is visible in Inspector.scan01-magick+exiftool.png - tagged time & place is not visible in Inspector. Convert the TIFF to PNG using OS X Preview program: Open 'scan01.tif' in Preview export as PNG. Convert the TIFF to PNG using ImageMagick convert: I cropped a large original TIFF image to 200x200 pixels. But your response in Topic 7461 means that maybe something else is going on. I thought this was because of the XMP-after-IDAT problem ( Topic 5347). But when I update certain PNG files, the tags are not visible to Mac utilities. I'd like to add time & place tags to some PNG files converted from original TIFF files.
