Format Specifications
Pict format 1 is probably a TGA file. The first four bytes are the picture type. The following 18 bytes would be consistent with TGA.
- uint32 {4} - Picture Type (1, 4, 8, etc.)
// Header (18 Bytes)
- uint8 {1}&nsbsp; - ID Length (0)
This field identifies the number of bytes contained in Field 6, the Image ID Field. The maximum
number of characters is 255. A value of zero indicates that no Image ID field is included with the
image.
- uint8 {1}&nsbsp; - Color Map Type (1)
This field indicates the type of color map (if any) included with the image. There are currently 2
defined values for this field:
0 - indicates that no color-map data is included with this image.
1 - indicates that a color-map is included with this image.
- uint8 {1}&nsbsp; - Image Type (1)
The TGA File Format can be used to store Pseudo-Color, True-Color and Direct-Color images of
various pixel depths. Truevision has currently defined seven image types:
0 No Image Data Included
1 Uncompressed, Color-mapped Image
2 Uncompressed, True-color Image
3 Uncompressed, Black-and-white Image
9 Run-length encoded, Color-mapped Image
10 Run-length encoded, True-color Image
11 Run-length encoded, Black-and-white Image
- uint16 {2} - Color Map, First Entry Index (0)
Index of the first color map entry. Index refers to the starting entry in
loading the color map.
- uint16 {2} - Color Map, Length(256)
Total number of color map entries included. - uint8 {1} - Color Map, Entry Size(32)
Establishes the number of bits per entry. Typically 15, 16, 24 or 32-bit values are used. - uint16 {2} - X-Origin of Image (0)
- uint16 {2} - Y-Origin of Image(0)
- uint16 {2} - Width (512)
- uint16 {2} - Height(256)
- uint8 {1} - Pixel Depth(0)
- uint8 {1} - Image Descriptor, Direction of data storage, see TGA spec for more info(0)
// Color Palette (256 Colors)
- // for each color
- byte {1} - Red
- byte {1} - Green
- byte {1} - Blue
- byte {1} - Alpha
- byte {1} - Red
// Image Data
- // for each pixel
- byte {1} - Palette Index
- byte {1} - Palette Index
