HsArtExtractor

A tool for windows to extract hearthstone card art from the unity game files. The project includes a partial port of Disunity, it also utilizes the DDSReader project.

Features

Extract all card art.
~~Extract available card bars (deck list images).~~
~~Extracts the card xml text files.~~
Extracted cards can be filtered by set and card type, they can also be named by card name rather than by id.

Usage

When Hearthstone is running the necessary game files cannot be accessed. Therefore, you need to quit out of Hearthstone for the program to work correctly.

Command line interface

extractor.exe cardart [options] <hearthstone directory>

Examples

Extract the card art including card bars to C:\CardArt directory, this excludes enchantments and miscellaneous sets.

extractor.exe cardart -o "C:\CardArt" "C:\Hearthstone"

Extract the full card art images only (no bars) and disable all default filtering on sets and card type.

extractor.exe cardart --full-only --no-filters -o "C:\CardArt" "C:\Hearthstone"

Extract the card bars with "hidden" areas cropped off, and set the output height to be 34 pixels. Also, use the supplied CardArtDefs.xml to create bars for tokens.

extractor.exe cardart -o "C:\CardArt" --crop-hidden --bar-height 34 --bar-only -m CardArtDefs.xml C:\Hearthstone
