Hi,
I need to create a button that capture automatically a picture (BMP) of the current frame to a specific folder...
I have created a button that call the function "SaveImageSeq". I have changed that function. I want to capture only 1 picture. So, I have to set the selection start to the current frame and the selection end to the following frame. (I need 2 frames to create a picture).
I am able to set the selection start with the function :
SendMessage(hwnd, WM_COMMAND, ID_EDIT_SETSELSTART, 0);
But I don't know how to set the selection end to the next frame...
Does somebody know how to selection the next frame by programmation?
Thanks...
==================================================
void SaveImageSeq(HWND hwnd) {
SaveImageSeqDlgData sisdd;
if (!inputVideoAVI) {
MessageBox(hwnd, "No input video stream to process.", g_szError, MB_OK);
return;
}
memset(&sisdd, 0, sizeof sisdd);
strcpy(sisdd.szDirectory,"C:\TEST");
//strcpy(sisdd.szFormat,sisdd.szDirectory);
sisdd.digits = 3;
strcpy(sisdd.szPrefix,"dcs");
sisdd.bSaveAsTGA = false;
strcpy(sisdd.szPostfix,".bmp");
// Set the selection start...
SendMessage(hwnd, WM_COMMAND, ID_EDIT_SETSELSTART, 0);
// Now I need to select the next frame as the selection end...
// I don't know how to do it!!!!!!!!!!!!!!!!
//SendMessage(hwnd, WM_COMMAND, ID_EDIT_SETSELEND, 0);
sisdd.lFirstFrame = inputVideoAVI->lSampleFirst;
sisdd.lLastFrame = inputVideoAVI->lSampleLast-1;
sisdd.bRunAsJob = false;
// if (DialogBoxParam(g_hInst, MAKEINTRESOURCE(IDD_AVIOUTPUTIMAGES_FORMAT), hwnd, SaveImageSeqDlgProc, (LPARAM)&sisdd)) {
SetAudioSource();
try {
if (sisdd.bRunAsJob)
JobAddConfigurationImages(&g_dubOpts, g_szInputAVIFile, FILETYPE_AUTODETECT, sisdd.szPrefix, sisdd.szPostfix, sisdd.digits, sisdd.bSaveAsTGA, &inputAVI->listFiles);
else
SaveImageSequence(sisdd.szPrefix, sisdd.szPostfix, sisdd.digits, false, NULL, sisdd.bSaveAsTGA);
} catch(const MyError& e) {
e.post(NULL, g_szError);
}
// }
}
==================================================

Use the clip list instead of the output range.
if (inputSubset)
delete inputSubset;
inputSubset = new FrameSubset;
inputSubset->addRange(nFrame, 1, false);

Thanks a lot!
Just a more thing...
The image is not save in the folder "C:\TEST" even if I do:
strcpy(sisdd.szDirectory,"C:\\TEST");
(the folder already exist)
We will give you some money for your help because it's very appreciated... |

That looks suspiciously like a regression I introduced in 1.4.11 and fixed in 1.4.12. The call to SaveImageSequence() is supposed to pass szFormat as the first parameter instead of szPrefix. However, szFormat is computed in the dialog code from szDirectory and szPrefix. So you might as well just pass the desired path directly instead of using the "sisdd" structure as an obfuscated set of local variables (the only reason it exists is for data exchange with the dialog).
