Dalam topik ini, kita akan mempelajari cara mengonversi EPS ke TIFF menggunakan C++. Anda akan mengamati cara memuat file EPS input dan mengonversinya menjadi gambar dalam C++ menggunakan panggilan API sederhana.
Langkah-langkah Mengkonversi EPS ke TIFF menggunakan C++
- Instal Aspose.Page for C++ dari NuGet package Manager Tool
- Tambahkan referensi ke Aspose::Page namespace
- Tentukan ImageFormat keluaran dan inisialisasi aliran masukan
- Muat file EPS input menggunakan objek kelas PsDocument
- Setel properti ImageSaveOptions dan simpan file TIFF keluaran
Anda dapat mengekspor EPS ke TIFF menggunakan C++ dengan menggunakan panggilan API sederhana dengan beberapa baris kode. Anda hanya perlu memuat file EPS input dan mengatur properti yang berbeda sesuai kebutuhan Anda, kemudian mengonversi file dengan PsDocument class menggunakan C++.
