how to extract from the parameters field

Thanks for your question and for the link to the metadata analysis results.

Your image looks like a PNG file; is that right? If so, can you post a link to the original image or contact me at my web site and send one or more images by email?

MLA uses PHP’s built-in functions to extract IPTC and EXIF metadata. These have not been updated to support the PNG format. MLA does have its own code for XMP metadata which might be useful.

On the Media/Edit Media screen, just below the “Attachment Metadata” box there should be another box labeled “Attachment File Metadata”. Is that box present, and does it show your metadata?

If I can get a copy of one or more of you images I can investigate further. Thanks for any samples you can provide.

Thank you for your reply I sent you email with the pictures attached

yes i think it stored in special metadata named PNG its like inside GPS metadata

Thanks for working with me by email to develop and test the MLA enhancements required to extract metadata from PNG image files. There is now a png: field-level prefix value to access the IHDR and tEXt metadata in these files.

Thanks as well for giving me the information I needed to develop the “MLA Diffusion Parameters Example” plugin that parses the “parameters” tEXt chunk values for image files generated by a diffusion image generator.

I have released MLA version 3.07, which contains the enhancements and new example plugin required for this topic.

I am marking this topic resolved, but please update it if you have any problems or further questions regarding MLA’s support for PNG metadata or Diffusion parameters. Thanks for inspiring this MLA improvement.
