API¶

::ico::icons file ?option value...?

Returns a list of icons found in file where each element is the name or numeric ID. Recognizes the following options:

::ico::iconMembers file name ?option value...?

Returns a list of images that make up the icon with ID name. Each element is itself a sublist in the format {name width height bpp}. Recognizes the following options:

::ico::getIcon file name ?option value...?

Extracts the icon with ID name from file. The default -format is image which will return the name of a Tk image containing the icon. The resolution and color depth are selected with the ?-res?, ?-bpp?, and ?-exact? options. If -exact is specified and there is no exact match, an error is thrown. Optionally -image may be used to specify the name of the Tk image that is created. If -format is colors then a list of color names in the #RRGGBB format is returned. Each list element is a horizontal row. Each horizontal row contains a list of colors for all the pixels in that row from left to right. If -format is name then the resource name of the image chosen is returned. This is useful for calling writeIcon or getIconByName. Recognizes the following options.

::ico::getIconByName file name ?option value...?

Extracts the image with ID name from file. This name should be the name of a specific image as returned by ::ico::iconMembers, not an icon name returned from ::ico::icons. If there is no matching resource ID in file an error is thrown. Recognizes the following options:

::ico::getFileIcon file ?option value...?

This command is only functional when running under Windows. It reads the Windows registry to determine the display icon for file as it would appear in Explorer or similar. file does not need to exist and may also be specified as a file extension with a leading dot. If file is a directory or you specify the special name Folder then the icon representing a folder is returned. This command takes the same arguments and usage as getIcon:

::ico::writeIcon file name depth data ?option value...?

Writes an image to file. name is the resource identifier of the image in file to write. When writing to an EXE, DLL, or ICL file you may only overwrite existing icons with an icon of the same dimensions and color depth. No icons may be added to these file types.

When writing to BMP the name is ignored as this type can contain only one image. This means if the file already existed it is completely overwritten.

When writing to an ICO or ICODATA file if the name specified does not exist then an image is appended and will be named the next in sequence (the specified name is ignored). Images in ICO and ICODATA files may be overwritten with differing dimensions or color depths. Note that you will get strange results when displaying icons if you fail to change every image which makes up a given icon.

::ico::copyIcon file index file2 index2 ? option value...?

Copies the icon at index in file to index2 in file2.

::ico::EXEtoICO file ?dir?

Extracts all icons from the executable file to ICO files placed in dir. ?dir? defaults to the directory file is located in. Icon files will be named in the form file-ID.ico where ID is the icon resource identifier.

::ico::clearCache ?file?

The ::ico::getIconList command caches icon offsets inside EXE, DLL, ICL, and ICO files in order to speed up extraction. This command clears that cache for the specific ?file? or all files.

::ico::transparentColor image color

If image is a single word it is assumed to be the name of a Tk image. All pixels matching color in the image will be set transparent. Alternatively, image may be a color list in which case a modified list is returned.

::ico::Show file ?option value...?

Application level command which displays a window showing all the icons in file and their name.

EXAMPLE¶

    button .explore -image [::ico::getIcon explorer.exe 0 -name explore -res 16 -bpp 8]

    set i [lsearch -inline [::ico::iconMembers tclkit.exe 0] {* 32 32 8}]
    set colorlist [::ico::getIconByName tclkit.exe [lindex $i 0] -format colors]
