I need to get the specific code that does that

Hi, I won't explain how to do this in Layout (SDK 25) , but here's the code that draws an image in a template, Master Layout (SDK 26). Where you place DO_CreatePicture, you can add lines, text, etc.

void QuantitiesDialog::Create_MasterLayout_Frame_A3(const char* masterLayoutName) { // Step 1: Retrieve the list of master layout templates GS::Array<API_DatabaseUnId> masterLayouts; GSErrCode err = ACAPI_Database(APIDb_GetMasterLayoutDatabasesID, nullptr, &masterLayouts); if (err != NoError) { WriteReport("Error while retrieving master layout templates: %d\n", err); return; } // Step 2: Find the template with the specified name API_DatabaseUnId targetMasterLayoutUnId = {}; for (const auto& dbUnId : masterLayouts) { API_DatabaseInfo dbInfo = {}; dbInfo.databaseUnId = dbUnId; err = ACAPI_Database(APIDb_GetDatabaseInfoID, &dbInfo); if (err == NoError) { GS::UniString dbName(reinterpret_cast<const GS::uchar_t*>(dbInfo.name)); if (dbName == masterLayoutName) { targetMasterLayoutUnId = dbUnId; break; } } else { WriteReport("Error while retrieving template info: %d\n", err); } } // Step 3: Check if the template was found if (targetMasterLayoutUnId.elemSetId == APINULLGuid) { WriteReport("Master layout template '%s' not found.\n", masterLayoutName); return; } // Step 4: Set the context to the selected master layout template API_DatabaseInfo dbInfo = {}; dbInfo.typeID = APIWind_MasterLayoutID; dbInfo.databaseUnId = targetMasterLayoutUnId; err = ACAPI_Database(APIDb_ChangeCurrentDatabaseID, &dbInfo); if (err != NoError) { WriteReport("Error while changing database to the master layout template: %d\n", err); return; } err = ACAPI_CallUndoableCommand("Rysowanie linii na szablonie arkusza", [&]() -> GSErrCode { // Additional elements (image and text) Do_CreatePicture("Logo.png", 0.365, 0.270, 0.001); if (err != NoError) { WriteReport("Error during operations in a context enabling undo: %d\n", err); } // Step 6: Refresh the view ACAPI_Automate(APIDo_RedrawID, nullptr, nullptr); } void QuantitiesDialog::Do_CreatePicture(GS::UniString picture_name, double my_X, double my_Y, double Scale_Factor) { // Initialize API_Element and API_ElementMemo API_Element element = {}; API_ElementMemo memo = {}; USize nBytes; API_Coord c = {}; USize rwnum = 0; Int32 hSize, vSize, hRes, vRes, pixelBitNum; GSErrCode err; // Step 1: Construct the full path to the picture file GS::UniString pictureFile = "Resources\\" + picture_name; GS::UniString fullPath = Set_myAddOnPath(pictureFile); IO::Location location(fullPath); // Step 2: Retrieve image file information (dimensions and resolution) err = GX::ImageBase::GetFileInfo(location, &hSize, &vSize, &hRes, &vRes, &pixelBitNum); if (err != NoError) { ErrorBeep("GX::ImageBase::GetFileInfo", err); return; } // Step 3: Calculate dimensions in millimeters based on resolution and scale factor double width_mm = (hSize / static_cast<double>(hRes)) * 25.4 * Scale_Factor; double height_mm = (vSize / static_cast<double>(vRes)) * 25.4 * Scale_Factor; // Step 4: Configure the picture element element.header.type = API_PictureID; element.picture.usePixelSize = false; // Set to true to use pixel dimensions instead of mm element.picture.mirrored = false; element.picture.destBox.xMin = my_X; element.picture.destBox.yMin = my_Y; element.picture.destBox.xMax = my_X + width_mm; // Add width in mm element.picture.destBox.yMax = my_Y + height_mm; // Add height in mm element.picture.rotAngle = 0.0; element.picture.anchorPoint = APIAnc_LB; element.picture.storageFormat = APIPictForm_PNG; element.picture.transparent = false; GS::ucscpy(element.picture.pictName, L("First try")); // Step 5: Open the image file and read its data into a memory handle IO::File file(location); file.Open(IO::File::ReadMode); if (file.GetDataLength(&nBytes) == NoError) { memo.pictHdl = BMAllocateHandle(nBytes, ALLOCATE_CLEAR, 0); if (memo.pictHdl != nullptr) { DBPrintf("Tiff file size: %d", nBytes); file.ReadBin(*memo.pictHdl, nBytes, &rwnum); if (rwnum != nBytes) err = ErrIO; } } else { err = ErrIO; } file.Close(); // Step 6: Create the picture element in the Archicad environment if (err == NoError) { err = ACAPI_Element_Create(&element, &memo); if (err != NoError) { WriteReport("ACAPI_Element_Create (picture)", err); } } // Step 7: Dispose of the memory handle to free resources if (memo.pictHdl != nullptr) { ACAPI_DisposeElemMemoHdls(&memo); } }

And here is the code (sdk 26) to insert drawing elements (like picture) into Layout. It use void QuantitiesDialog::Do_CreatePicture form above. Be careful about the coordinates of the inserted elements, because before You select the values, you will often have them outside the layout area. That's why I added "zoom" in the code. I hope that based on this code you will adopt it to version 25

void QuantitiesDialog::Show_Layout(const char* LayoutName) { API_DatabaseUnId targetLayoutUnId = {}; API_DatabaseInfo dbInfo = {}; WriteReport("Starting Show_Layout for layout '%s'.\n", LayoutName); // Retrieve the list of layouts GS::Array<API_DatabaseUnId> layouts; GSErrCode err = ACAPI_Database(APIDb_GetLayoutDatabasesID, nullptr, &layouts); if (err != NoError) { WriteReport("Error retrieving layout list. Error code: %d\n", err); return; } // Search for the specified layout bool layoutFound = false; for (const auto& dbUnId : layouts) { dbInfo.databaseUnId = dbUnId; if (ACAPI_Database(APIDb_GetDatabaseInfoID, &dbInfo) == NoError) { GS::UniString dbName(reinterpret_cast<const GS::uchar_t*>(dbInfo.name)); if (dbName.ToCStr() != nullptr && strcmp(dbName.ToCStr(), LayoutName) == 0) { targetLayoutUnId = dbUnId; layoutFound = true; WriteReport("Layout '%s' found.\n", LayoutName); break; } } } if (!layoutFound) { WriteReport("Layout '%s' not found.\n", LayoutName); return; } // Switch to the specified layout API_WindowInfo windInfo = {}; windInfo.typeID = APIWind_LayoutID; // Window type: Layout windInfo.databaseUnId = targetLayoutUnId; err = ACAPI_Automate(APIDo_ChangeWindowID, &windInfo); if (err == NoError) { // Draw objects on the layout err = ACAPI_CallUndoableCommand("Drawing on layout", [&]() -> GSErrCode { // Insert here any object which need ACAPI_CallUndoableCommand // add Do_CreatePicture("Logo.png", 0.1100, 0.200, 0.001); // Insert a picture // add return NoError; }); if (err != NoError) { WriteReport("Error during undoable command operation: %d\n", err); } // Fit the view to the layout GSErrCode zoomErr = ACAPI_Automate(APIDo_ZoomID); if (zoomErr == NoError) { WriteReport("View fitted to layout '%s'.\n", LayoutName); } else { WriteReport("Error fitting view to layout '%s'. Error code: %d\n", LayoutName, zoomErr); } } else { WriteReport("Error switching to layout '%s'. Error code: %d\n", LayoutName, err); } }
