Vault 7: Projects

This publication series is about specific projects related to the Vault 7 main publication.

A resource in the library has three major characteristics:
1. Location or source of the resource - The following are the recognized sources of resources
internal flash memory type
internal RAM type
external memory type
external EDS memory type
2. Data types of the resource - The following are the supported types of resources:
image
font
palette
binary data
3. Data compression type of the resource - the following are the supported compression of data:
RLE - Run length encoded compression. This type of compression is only available for 8 and 4 bpp bitmaps.
IPU - Compressed data is encoded using the DEFLATE algorithm with fixed Huffman codes; dynamic Huffman codes are
not supported.
The first four types indicates the location of the resource. The next five types indicates which kind of resource and the next 3
types indicates if the resource data is compressed or not.
By combining these three groups, a resource can be described fully and accessed appropriately in the library. For example:
By combining the location, type and compression into one type, the library can pass the resource type parameter when
rendering the resource. GFX_RESOURCE_MCHP_MBITMAP_EXTERNAL_RLE = (
GFX_RESOURCE_TYPE_MCHP_MBITMAP | GFX_RESOURCE_MEMORY_EXTERNAL |
GFX_RESOURCE_COMP_RLE )
Each type will determine how the library will access the resource when rendering.
Remarks
None.
