IMAGE INFO
From AVObjects Knowledge Base
The IMAGE_INFO structure is used in some methods of the Text & Graphics Overlay Filter for adding an image to overlay from memory.
Syntax
typedef struct IMAGE_INFO { LONG biWidth; LONG biHeight; WORD biBitCOunt; DWORD biCompression; DWORD biSizeImage; } IMAGE_INFO;
Structure members
The following table lists the members exposed by the IMAGE_INFO structure.
Name | Description |
biWidth | Image width. |
biHeight | Image height. |
biBitCount | Image color depth. Equals to either 24 or 32. |
biCompression | Equals only to BI_RGB(0). |
biSizeImage | Image size. |
Remarks
- Only 24 and 32 bits bitmaps are supported in the current version. For 32 bits bitmaps ARGB32 bitmaps are assumed.
- If biHeight contains a positive value, the bitmap is a bottom-up DIB with its origin at the lower-left corner. If the value is negative, the bitmap is a top-down DIB with the originat the upper-left corner.
