winres-edit
Crate for modification of windows resources.
Overview
This crate allows you to create, load and modify Windows resources inside of .exe
and .res
files. This crate currently does not support actual resource data destructuring with exception of Version Strings (VS_VERSION_INFO), which is useful to modify application manifests. Loaded resources are available as raw Vec<u8>
data, useful to modify bitmaps and icons.
Please note that all operations performed on the opened resource file are accumulated and are then "flushed" to the file when the file is closed
using the close()
function. This is due to the behavior of the underlying Win32 API (UpdateResource) functionality used by this crate.
Example
Modifying icon data and resource strings
let mut resources = Resources::new(&Path::new("myfile.exe"));
resources.load().expect("Unable to load resources");
resources.open().expect("Unable to open resource file for updates");
resources.find(resource_type::ICON,Id::Integer(1))
.expect("unable to find main icon")
.replace(icon_data)?
.update()?;
let version: [u16;4] = [0,1,0,0];
resources.get_version_info()?.expect("Unable to get version info")
.set_file_version(&version)
.set_product_version(&version)
.insert_strings(
&[
("ProductName","My Product")
("FileDescription","My File")
]
)
.remove_string("SomeExistingString")
.update()?;
// make sure to explicitly call close() as that flushes all the session changes
resources.close();
Adding a new icon
let res = Resource::new(
&resources,
resource_type::ICON.into(),
Id::Integer(14).into(),
1033,
target_icon.data(),
);
res.update()?;
Icons
This crate works well in conjunction with the ico
crate that can be used to load/store external .ico
files as well as load .png
files and encode them into windows-compatible resource format.
Example
let iconfile = std::fs::File::open("myicon.ico").unwrap();
let icon_dir = ico::IconDir::read(iconfile).unwrap();
let target_icon = icon_dir
.entries()
.iter()
.find(|&e| e.width() == 256)
.expect("can't find 256x256 icon");
let icon_data = target_icon.data();
This crate also works well in conjunction with the image
crate that can interact with the ico
crate to load, resize and and store custom icons within resource files.
