2024-06-13utils: raspberrypi: ctt: Adapt tuning tool for both VC4 and PiSPDavid Plowman
The old ctt.py and alsc_only.py scripts are removed. Instead of ctt.py use ctt_vc4.py or ctt_pisp.py, depending on your target platform. Instead of alsc_only.py use alsc_vc4.py or alsc_pisp.py, again according to your platform.

2024-05-08libcamera: Drop file name from header comment blocksLaurent Pinchart
Source files in libcamera start by a comment block header, which includes the file name and a one-line description of the file contents. While the latter is useful to get a quick overview of the file contents at a glance, the former is mostly a source of inconvenience. The name in the comments can easily get out of sync with the file name when files are renamed, and copy & paste during development have often lead to incorrect names being used to start with. Readers of the source code are expected to know which file they're looking it. Drop the file name from the header comment block. The change was generated with the following script: ---------------------------------------- dirs="include/libcamera src test utils" declare -rA patterns=( ['c']=' \* ' ['cpp']=' \* ' ['h']=' \* ' ['py']='# ' ['sh']='# ' ) for ext in ${!patterns[@]} ; do files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done) pattern=${patterns[${ext}]} for file in $files ; do name=$(basename ${file}) sed -i "s/^\(${pattern}\)${name} - /\1/" "$file" done done ---------------------------------------- This misses several files that are out of sync with the comment block header. Those will be addressed separately and manually. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Daniel Scally <dan.scally@ideasonboard.com>

2024-01-09utils: raspberrypi: ctt: Improve the Macbeth Chart search reliabilityDavid Plowman
Previously the code would brighten up images in case the Macbeth Chart is slightly dark, and also zoom in on sections of it to look for charts occupying less of the field of view. But it would not do both together. This change makes the search for smaller charts also repeat that search for the brightened up images that it made earlier, thereby increasing the chances of success for non-optimal tuning images. There are also a couple of very small drive-by typo fixes.

2022-08-03utils: raspberrypi: ctt: dng_load_image: Work with DNG files from Picamera2William Vinnicombe
The DNG specification is based on the TIFF file format and recommends storing the raw image data in a SubIFD and the Exif tags in an Exif IFD. Other options are allowed, even if not recommended, such as storing both the raw image data and the Exif data in IFD0, as done by the TIFF/EP specification. libcamera-apps use pyexiv2 to produce DNG files, following the DNG recommendation, while applications based on picamera2 use PiDNG, which adopts the TIFF/EP structure. Why it does so is not currently clear (see https://github.com/schoolpost/PiDNG/issues/65 for discussions on this topic), but as files based on the DNG and TIFF/EP variants exist in the wild, both need to be supported by ctt. Add code to identify which tags are being used, and then load the metadata from the correct tags.
