LoadInfoFlags property (Main Control)

Cardinal LoadInfoFlags |

Delphi Syntax |
LoadInfoFlags: Cardinal |
|
Overview |
Refer to Loading a Bitmap from a File. |
Remarks
Specifies format information about the image data to be loaded. LEADTOOLS uses these flags only if it fails to find the value in the file header. You can use this and the other LoadInfo... properties for loading raw FAX data (CCITT Group 3 or Group 4) and RAW uncompressed data.
LEADTOOLS checks the LoadInfoFormat property first. If that property has a non-zero value, it uses the other LoadInfo... property values. Keep in mind that when these values are used, LEADTOOLS does not validate the data in the file. If you want LEADTOOLS to validate the data, you must set the LoadInfoFormat property to zero.
The following are valid values. When it is appropriate, you can use a bitwise OR ( | ) to specify more than one value.
LOADINFO_TOPLEFT, LOADINFO_TOPLEFT90 and LOADINFO_TOPLEFT270 cannot be combined using the bitwise OR.
LOADINFO_REVERSE can be combined with LOADINFO_TOPLEFT, LOADINFO_TOPLEFT90 or LOADINFO_TOPLEFT270. If LOADINFO_REVERSE is set, every line is reversed before being put into the bitmap.
