Microsoft^® Visio Memformat Konversi Melalui Java

Konversikan MS Visio Diagram ke HTML, PDF, dan Gambar termasuk JPG, BMP, PNG, TIFF untuk membangun aplikasi Java lintas platform.

Untuk solusi rendering format Microsoft Visio apa pun seperti merancang diagram alur dan diagram alur bisnis, dll. Java Visio API memfasilitasi semua gambar kompleks dengan cara yang mudah. Muat file sumber menggunakan Diagram kelas dan panggil metode simpan dengan parameter yang sesuai.

Antar Konversi Visio File

Pemrogram dapat dengan mudah mengonversi format VSDX, VSX, VTX, VDX, VSSX, VSTX, VSDM, VSSM, VSTM serta memuat VDW, VSD, VSS, VST dan merender ke PDF, HTML, dan Gambar. Mempertimbangkan skenario VSDX hingga VDX, prosesnya adalah, memuat file sumber VSDX menggunakan kelas diagram dan memanggil metode simpan dengan menyediakan file output dan SimpanFormat File .VDX sebagai parameter.

Java Kode untuk VSDX ke VDX Konversi

	// Load the VSDX in an object of Diagram
	Diagram visio = new Diagram("template.vsdx");

	// save VSDX as VDX
	visio.save("output.vdx", SaveFileFormat.VDX);

Visio ke Konversi Gambar

Untuk konversi umum, proses mengonversi visio file menjadi gambar adalah sama. Cukup muat file melalui kelas Diagram dan panggil metode simpan dengan file keluaran dan parameter keluaran SaveFileFormat. Dan kapan pun diperlukan untuk menentukan opsi tertentu, pengembang dapat menggunakan kelas ImageSaveOptions saat mengonversi diagram halaman menjadi gambar dan SVGSaveOptions untuk konversi SVG.

Java Kode untuk Mengonversi Visio ke Format Gambar

	Diagram vsdxtoImages = new Diagram("sourceDocument.vsdx");

	ImageSaveOptions ImgOptions = new ImageSaveOptions(SaveFileFormat.JPEG);

	// specify the quality level to use during compositing.
	ImgOptions.setCompositingQuality(CompositingQuality.HIGH_QUALITY);

	//The default value is 0.5. The value must be in the range between 0 and 1.
	ImgOptions.setImageBrightness(1f);

	ImgOptions.setDefaultFont("MS Gothic");

	// sets the number of pages to render in image.
	ImgOptions.setPageCount(2);

	// sets the 0-based index of the first page to render. Default is 0.
	ImgOptions.setPageIndex(0);

	// set page size
	PageSize pgSize = new PageSize(PaperSizeFormat.A_1);
	ImgOptions.setPageSize(pgSize);

	// discard saving background pages of the Visio diagram
	ImgOptions.setSaveForegroundPagesOnly(true);

	// sets the color mode for the generated images.
	ImgOptions.setImageColorMode(ImageColorMode.BLACK_AND_WHITE);

	// the default value is 0.5. The value must be in the range between 0 and 1.
	ImgOptions.setImageContrast(1f);

	// this property has effect only when saving to raster image formats.
	ImgOptions.setInterpolationMode(InterpolationMode.NEAREST_NEIGHBOR);

	// the value may vary from 0 to 100 where 0 means worst quality,
	ImgOptions.setJpegQuality(100);

	// set a value specifying how pixels are offset during rendering.
	ImgOptions.setPixelOffsetMode(PixelOffsetMode.HIGH_SPEED);

	// sets the resolution for the generated images, in dots per inch. The default value is 96.
	ImgOptions.setResolution(2f);

	// the default value is 1.0. The value must be greater than 0.
	ImgOptions.setScale(1f);

	// specify whether smoothing (antialiasing) is applied to lines
	// and curves and the edges of filled areas.
	ImgOptions.setSmoothingMode(SmoothingMode.HIGH_QUALITY);
	// sets the type of compression to apply when saving generated images to the TIFF format.
	ImgOptions.setTiffCompression(TiffCompression.CCITT_3);

	// save in visio file into image of choice
	vsdxtoImages.save("visiofiletoimage_Out.jpeg", ImgOptions);

Konversikan Visio ke PDF dan HTML

API mampu mengonversi visio format ke PDF serta HTML. Gunakan saja SimpanFormat File .PDF dan SaveFileFormat.HTML dalam metode simpan sebagai parameter. Dan untuk pengaturan khusus, pengembang dapat menggunakan kelas PdfSaveOptions dan HTMLSaveOptions.

Java Kode untuk Konversi Visio ke PDF

	// call the diagram constructor to load diagram from a VSDX file
	Diagram vsdxtopdf = new Diagram("sourfile.vsdx");

	// Options when saving a diagram into the PDF format
	PdfSaveOptions pdfOpts = new PdfSaveOptions();

	// discard saving background pages of the Visio diagram
	pdfOpts.setSaveForegroundPagesOnly(true);

	// specify the quality of JPEG compression for images (if JPEG compression is used). Default is 95.
	pdfOpts.setJpegQuality(100);

	// specify default font name
	pdfOpts.setDefaultFont("Arial");

	// conformance level for generated PDF document.
	pdfOpts.setCompliance(PdfCompliance.PDF_15);

	// sets a digital signature details. If not set, then no signing will be performed.
	pdfOpts.setDigitalSignatureDetails(new PdfDigitalSignatureDetails(cert, "Test Signing", "Aspose Office", DateTime.getNow(), PdfDigitalSignatureHashAlgorithm.SHA_256));

	// set encription details
	PdfEncryptionDetails encriptionDetails = new PdfEncryptionDetails("user password", "Owner Password", PdfEncryptionAlgorithm.RC_4_128);
	pdfOpts.setEncryptionDetails(encriptionDetails);
	// sets the number of pages to render in PDF.
	pdfOpts.setPageCount(2);
	// sets the 0-based index of the first page to render. Default is 0.
	pdfOpts.setPageIndex(0);

	// set page size
	PageSize pgSize = new PageSize(PaperSizeFormat.A_1);
	pdfOpts.setPageSize(pgSize);

	// save in visio file into PDF
	vsdxtopdf.save("UsePDFSaveOptions_Out.pdf", pdfOpts);

Java Kode untuk Mengonversi Visio ke Berkas HTML

	// call the diagram constructor to load diagram from a VSDX file
	Diagram vsdxtohtml = new Diagram("sourceFile.vsdx");

	// Options when saving a diagram into the HTML format
	HTMLSaveOptions htmlOpt = new HTMLSaveOptions();

	htmlOpt.setDefaultFont("MS Gothic");
	// sets the number of pages to render in HTML.
	htmlOpt.setPageCount(2);
	// sets the 0-based index of the first page to render. Default is 0.
	htmlOpt.setPageIndex(0);

	// set page size
	PageSize pgSize = new PageSize(PaperSizeFormat.A_1);
