imageTagger 0.5 (Default branch)
11-20-2008
imageTagger makes it easy to manage tags ofdifferent images and so organise large collectionsof image collections. It features the ability toassign free tags to images and to search forpictures with tags. The tags are storedexternally, so this can also be used for filesthat should not be changed, files on CDs, andpictures in a format that does not supportmetadate. No image data is changed ever.License: GNU General Public License (GPL)Changes:|

image(n) Tk Built-In Commands image(n) __________________________________________________________________________________________________________________________________________________ NAME
image - Create and manipulate images SYNOPSIS
image option ?arg arg ...? _________________________________________________________________ DESCRIPTION
The image command is used to create, delete, and query images. It can take several different forms, depending on the option argument. The legal forms are: image create type ?name? ?option value ...? Creates a new image and returns its name. type specifies the type of the image, which must be one of the types currently defined (e.g., bitmap). name specifies the name for the image; if it is omitted then Tk picks a name of the form imagex, where x is an integer. There may be any number of option-value pairs, which provide configuration options for the new image. The legal set of options is defined separately for each image type; see below for details on the options for built-in image types. If an image already exists by the given name then it is replaced with the new image and any instances of that image will redisplay with the new contents. It is important to note that the image command will silently overwrite any procedure that may currently be defined by the given name, so choose the name wisely. It is recommended to use a separate namespace for image names (e.g., ::img::logo, ::img::large). image delete ?name name ...? Deletes each of the named images and returns an empty string. If there are instances of the images displayed in widgets, the images won't actually be deleted until all of the instances are released. However, the association between the instances and the image manager will be dropped. Existing instances will retain their sizes but redisplay as empty areas. If a deleted image is recreated with another call to image create, the existing instances will use the new image. image height name Returns a decimal string giving the height of image name in pixels. image names Returns a list containing the names of all existing images. image type name Returns the type of image name (the value of the type argument to image create when the image was created). image types Returns a list whose elements are all of the valid image types (i.e., all of the values that may be supplied for the type argument to image create). image width name Returns a decimal string giving the width of image name in pixels. BUILT-IN IMAGE TYPES The following image types are defined by Tk so they will be available in any Tk application. Individual applications or extensions may define additional types. bitmap Each pixel in the image displays a foreground color, a background color, or nothing. See the bitmap manual entry for more informa- tion. photo Displays a variety of full-color images, using dithering to approximate colors on displays with limited color capabilities. See the photo manual entry for more information. KEYWORDS
