Req #34622 [Opn->Sus]: Add image functions to support editing/creating "comments"

Edit report at https://bugs.php.net/bug.php?id=34622&edit=1 ID: 34622 Updated by: cmb@php.net Reported by: smc+phpbugs at dogphilosophy dot net Summary: Add image functions to support editing/creating "comments" -Status: Open +Status: Suspended Type: Feature/Change Request -Package: EXIF related +Package: *Graphics related Operating System: Linux PHP Version: Next Minor Version Block user comment: N Private report: N New Comment: libgd has still no support for image meta data whatsoever, so adding this functionality to the GD extension doesn't make sense. Instead this should be added upstream[1] first, and then we could add wrappers for that. Adding write support for EXIF might make sense, but it is certainly a lot of work, and I'm not convinced that this isn't better be done in userland, and apparently there are some packages already available[2]. But frankly, I'm not even sure that this feature request is about EXIF; there are several competing and partially overlapping "standards" for adding meta information to images. Anyhow, if anybody is still interested in this, please pursue the RFC process[3]. For the time being, I'm suspending this ticket.

EXIF support only covers reading information, not creating or editing records for images. Either ability to read and write "comments" (imagewritepngtext($image)? imagewritejpegcomment($image)?) or even just ability to create and write EXIF data in the EXIF functions would be nice. Reproduce code: --------------- (N/A) Expected result: ---------------- Ability to generate (for example) geotag information for .jpeg images, or for PNG-format map images generated in PHP. Actual result: -------------- (N/A - feature request for new functions) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=34622&edit=1
