IMAGE INFO

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
Filter properties related methods
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.
