display-image 0.1.0

PyQt6 Gui App to display the wide range image formats (jpg, png, tif, dng, bmp, and RAWs), with image metadata and histogram.

Display Image

Display image is a Python project which provides a command display-image to visualize the image and metadata by QtPy6.

display-image -i <path_to_image>

The following format extensions can be displayed by command display-image

Image format	Read	EXIF	Pixel precision	Pixel type	File extension	Sidecar needed
BMP	x		8 bits	Grayscale, RGB, RGBA	.bmp
CFA	x		16 bits	Bayer	.cfa
DNG	x	x	16 bits	Bayer	.dng
JPEG	x	x	8 bits	Grayscale, RGB	.jpg, .jpeg
MIPI RAW	x		10 bits, 12 bits	Bayer	.RAWMIPI, .RAWMIPI10, .RAWMIPI12	x
PLAIN RAW	x		*	*	.raw .plain16, *	x
PNG	x		8 bits	Grayscale, RGB, RGBA	.png
TIFF	x	x	8 bits, 16 bits	Bayer, RGB	.tif, .tiff

Image display with sidecar JSON

Some file formats need to know in advance some informations about the image. For example, the PLAIN RAW format is just a simple dump of a buffer into a file, thus it needs to know how to interpret the data. In this case, user need to have an image sidecar JSON located next to the image file as the same name and path path_to_image.json

{
    "fileInfo": {
        "format": "plain",
        "height": 3072,
        "width": 4080
        "pixelPrecision": 16,
        "pixelType": "bayer_gbrg",
    }
}

After image reading, the information in JSON sidecar will be shown in tab Widegt of ImageMetadata
