Mari 4.5v2 docs:

Image Manager Palette

The Image Manager palette and the controls that can be found on it are described in the table below. When controls also bring up additional dialogs, these are referenced for more information.

What It Does

The Image Manager lets you store and work with images in your project, including using them for brushes and painting through them onto your model. For organization purposes, you can also add custom tabs to the palette by clicking the add tab button.

Image Manager Palette Fields

Control	Type	What it does	Opens this dialog box
Image Info > Info
Depth	information	The color depth of the currently selected image in bytes.
Channels	information	The color components of the currently selected image.
File Space	dropdown	File space of the currently selected image from the options: • NORMAL • VECTOR • VECTOR_Y_FLIP • NORMAL_Y_FLIP
Tiled Image	information	Whether the image is tiled - true or false.
Height	information	The height of the currently selected image in pixels.
Width	information	The width of the currently selected image in pixels.
Path	information	The file path to the image that Mari is accessing. If the original image was saved to another location this is the file path shown, not the path to the original file.
Image Info > User Attributes
Comment	entry box	Assign a user-defined comment to the image.
MriImportFilePath	information	The file path to the original image.
MriLastImportDateTime	information	The date and time that the file was first loaded into Mari.
Colorspace
Colorspace	dropdown	The colorspace to which the output values are converted. Automatic is determined by the file name, size, and type of data in the image.
Raw Data	checkbox	If this is enabled, the image data is not converted. Note: As the raw colorspace nullifies the corresponding colorspace transform when either used as the input or output, there is a discrepancy between what is shown in the Image Manage palette thumbnail and the image viewer. This is the expected behavior.
	button	Adds an image to the Image Manager.	Open an Image Dialog
	button	Removes the selected image from the Image Manager.
	button	Opens the selected image in another window, where you can crop it.	<image>
	button	Saves the selected image to a file.	Save As Dialog
<image> window
	button	Crops the current image. Mari copies the cropped area as a separate image in the Image Manager. The cropped image is part of the project, but won't be saved as a separate image file unless you use the Save As option. Select one of the following crop modes: • Arbitrary - click-and-drag on an arbitrary area of the image. • Fixed - enter a fixed size for the crop box (in pixels) and drag it to the area you want to crop. • Aspect - enter a fixed aspect ratio for the crop box (in pixels) and drag it over the area you want to crop. Once you have selected the crop area, click the mouse button to crop.
Colorspace	dropdown	The colorspace to which the output values are converted. Automatic is determined by the file name, size, and type of data in the image.
Raw Data	checkbox	If this is enabled, the image data is not converted. Note: As the raw colorspace nullifies the corresponding colorspace transform when either used as the input or output, there is a discrepancy between what is shown in the Image Manage palette thumbnail and the image viewer. This is the expected behavior.
