Syntax
INT is_SaveImageMemEx (HIDS hCam, const IS_CHAR* File, char* pcMem, INT nID, INT fileFormat, INT Param)
Description
|
This function is obsolete and should not be used anymore. We recommend to use the is_ImageFile() function instead. |
is_SaveImageMemEx() saves an image in bitmap (*.BMP), JPEG (*.JPG), or PNG format to a file. The images are read out from the specified image memory. The bitmap is stored with the color depth that was used when allocating the image memory (in DIB mode) or that was set for the current color mode (in Direct3D mode). JPEG files are always saved with a color depth of 8 or 24 bits.
|
You can save images with a bit depth of more than 8 bit in the PNG format. 12 bit formats are converted into 16 bit. |
|
In Direct3D mode, overlay data is not saved. |
Input parameters
hCam |
Camera handle |
File |
Pointer to a string containing the BMP filename. You can either pass an absolute or a relative path. If NULL is passed, the "Save as" dialog will be displayed.. |
pcMem |
Pointer to the image memory |
nID |
Image memory ID |
fileFormat |
Specifies the output format of the file. |
IS_IMG_BMP |
Bitmap format |
IS_IMG_JPG |
JPEG format |
IS_IMG_PNG |
PNG format |
Param |
When you use IS_IMG_JPG or IS_IMG_PNG to specify the file format, you can set the quality by specifying a value between 1 and 100 for Param. If Param=0, the system uses the default quality (75). If you use IS_IMG_BMP, Param does not take effect. |
