The text of the first book of [De finibus bonorum et malorum](https://en.wikipedia.org/wiki/De_finibus_bonorum_et_malorum) was manually inserted in that file under the tag `xmp:Label` and the second book under the tag `xmp:Nickname` (any `<` or `>` removed to avoid conflicts with XMP). The file was reconstructed with `exiftool -tagsfromfile paris_exif_xmp_icc.xmp -Exif= -icc_profile= paris_exif_xmp_icc.jpg -o paris_extended_xmp.jpg`. The goal is to have a large XMP blob so that it can only be stored as multiple extended XMP chunks. | address | marker | length | data | |---------:|-------------|-------:|----------------------------------| | 0 | 0xffd8 SOI | | | | 2 | 0xffe0 APP0 | 16 | `JFIF.....,.,.` | | 20 | 0xffe1 APP1 | 5531 | http://ns.adobe.com/xap/1.0/.<?x | | 5553 | 0xffe1 APP1 | 65535 | http://ns.adobe.com/xmp/extensio | | 71090 | 0xffe1 APP1 | 65535 | http://ns.adobe.com/xmp/extensio | | 136627 | 0xffe1 APP1 | 4791 | http://ns.adobe.com/xmp/extensio | | | | | ... | ### File [paris_icc_exif_xmp.png](paris_icc_exif_xmp.png)  License: [same as libavif](https://github.com/AOMediaCodec/libavif/blob/main/LICENSE) Source: `paris_exif_xmp_icc.jpg` loaded with `avifReadImage()` then written with `avifPNGWrite()` (modified to output metadata this way). | address | marker | length | data | |--------:|--------|-------:|----------------------------------| | 8 | IHDR | 13 | | | 33 | iCCP | 386 | `libavif..(.u..+DQ..?3...E.....` | | 431 | zTXt | 631 | `Raw profile type exif..H...[..` | | 1074 | zTXt | 1076 | `Raw profile type xmp..X..YQ..8` | | 2162 | IDAT | | ... | | 160456 | IEND | 0 | | ### File [paris_icc_exif_xmp_at_end.png](paris_icc_exif_xmp_at_end.png)  License: [same as libavif](https://github.com/AOMediaCodec/libavif/blob/main/LICENSE) Source: `paris_exif_xmp_icc.jpg` loaded with `avifReadImage()` then written with `avifPNGWrite()` (modified to output metadata this way). | address | marker | length | data | |--------:|--------|-------:|----------------------------------| | 8 | IHDR | 13 | | | 33 | iCCP | 386 | `libavif..(.u..+DQ..?3...E.....` | | 2162 | IDAT | | ... | | 151474 | eXIf | 1126 | `II*..........................` | | 152612 | tEXt | 7832 | `Raw profile type xmp..XMP.0000` | | 160456 | IEND | 0 | | ### File [paris_exif_orientation_5.jpg](paris_exif_orientation_5.jpg)  License: [same as libavif](https://github.com/AOMediaCodec/libavif/blob/main/LICENSE) Source: `paris_exif_xmp_icc.jpg` stripped from all metadata with `exiftool -all=` and Exif orientation added with `exiv2 -k -M "set Exif.Image.Orientation 5"` | address | marker | length | data | |--------:|-------------|--------:|--------------------------------------| | 0 | 0xffd8 SOI | | | | 2 | 0xffe1 APP1 | 34 | `Exif..II*......................` | | | | | ... | ### File [paris_icc_exif_xmp.avif](paris_icc_exif_xmp.avif)  License: [same as libavif](https://github.com/AOMediaCodec/libavif/blob/main/LICENSE) Source: Encoded from `paris_icc_exif_xmp.png` using `avifenc -s 10` at commit ed52c1b. ## Grid ### File [sofa_grid1x5_420.avif](sofa_grid1x5_420.avif)  License: [same as libavif](https://github.com/AOMediaCodec/libavif/blob/main/LICENSE) Source: Personal photo converted with `avifenc --grid 1x5 --yuv 420` at commit [632d131](https://github.com/AOMediaCodec/libavif/commit/632d13188f9b7faa40f20d870e792174b8b5b8e6).
