This command will copy a selected area of the current bitmap. Amongst other things, you can use this command to store sequences of image data and provide animations for sprites. When images are grabbed, they are stored in memory and do not require the bitmap from which the image was taken. The parameters should be specified using integer values. You cannot grab an image while the target pixels are being locked by the LOCK PIXELS command, as it is not possible to read from a surface that is using the fast write only lock method on the pixels. Use the following texture flags:0-use stretching, filter, colorkey1-no stretching, no filter, colorkey2-use stretching, no filter, no colorkey (grab from alpha bitmap retain alpha channel)3-no stretching, no filter, no colorkey (grab from alpha bitmap retain alpha channel)
