Aspose.Slides FOSS for C++ lets you apply professional-quality visual effects to PowerPoint shapes in native C++, with no Microsoft Office and no API keys. This post demonstrates the fill system, 2D effects, and 3D formatting available in the library.
Sistem Isian
Setiap bentuk memiliki sebuah fill_format() yang mengontrol bagaimana interiornya diwarnai. Lima jenis isian mencakup seluruh rentang palet desain PowerPoint.
Isian Solid
Isian paling sederhana, warna datar dengan transparansi opsional:
#include <Aspose/Slides/Foss/presentation.h>
using namespace Aspose::Slides::Foss;
Presentation prs;
auto& shape = prs.slides()[0].shapes().add_auto_shape(
ShapeType::RoundCornerRectangle, 100, 100, 400, 150
);
shape.text_frame()->set_text("Solid Fill");
shape.fill_format().set_fill_type(FillType::SOLID);
shape.fill_format().solid_fill_color().set_color(Color::from_argb(255, 30, 80, 180));
prs.save("solid.pptx", SaveFormat::PPTX);
Isian Gradien Linear
Titik henti gradien memungkinkan Anda mencampur satu warna ke warna lain di seluruh bentuk:
#include <Aspose/Slides/Foss/presentation.h>
using namespace Aspose::Slides::Foss;
Presentation prs;
auto& shape = prs.slides()[0].shapes().add_auto_shape(
ShapeType::RECTANGLE, 100, 100, 400, 150
);
auto& ff = shape.fill_format();
ff.set_fill_type(FillType::GRADIENT);
auto& gf = ff.gradient_format();
gf.set_gradient_shape(GradientShape::Linear);
gf.set_linear_gradient_angle(90); // top-to-bottom
gf.gradient_stops().add(0.0f, Color::from_argb(255, 30, 80, 180)); // top: blue
gf.gradient_stops().add(1.0f, Color::from_argb(255, 0, 200, 160)); // bottom: teal
prs.save("gradient.pptx", SaveFormat::PPTX);
2D Visual Effects
Bayangan Jatuh Luar
Lampirkan bayangan jatuh semi-transparan pada bentuk apa pun:
#include <Aspose/Slides/Foss/presentation.h>
using namespace Aspose::Slides::Foss;
Presentation prs;
auto& shape = prs.slides()[0].shapes().add_auto_shape(
ShapeType::RoundCornerRectangle, 100, 100, 350, 150
);
shape.text_frame()->set_text("Drop Shadow");
shape.fill_format().set_fill_type(FillType::SOLID);
shape.fill_format().solid_fill_color().set_color(Color::white());
auto& ef = shape.effect_format();
ef.enable_outer_shadow_effect();
ef.outer_shadow_effect().set_blur_radius(12);
ef.outer_shadow_effect().set_direction(315); // upper-left
ef.outer_shadow_effect().set_distance(8);
ef.outer_shadow_effect().shadow_color().set_color(Color::from_argb(100, 0, 0, 0));
prs.save("shadow.pptx", SaveFormat::PPTX);
Efek Cahaya
Halo berwarna di sekitar tepi bentuk:
#include <Aspose/Slides/Foss/presentation.h>
using namespace Aspose::Slides::Foss;
Presentation prs;
auto& shape = prs.slides()[0].shapes().add_auto_shape(
ShapeType::Ellipse, 150, 100, 250, 250
);
shape.fill_format().set_fill_type(FillType::SOLID);
shape.fill_format().solid_fill_color().set_color(Color::from_argb(255, 20, 60, 140));
auto& ef = shape.effect_format();
ef.enable_glow_effect();
ef.glow_effect().set_radius(20);
ef.glow_effect().color().set_color(Color::from_argb(200, 0, 180, 255));
prs.save("glow.pptx", SaveFormat::PPTX);
3D Formatting
Bevel dan Material
Metode three_d_format() metode memberikan setiap bentuk datar tampilan tiga dimensi. Gabungkan bevel dengan preset kamera dan material untuk hasil paling kaya:
#include <Aspose/Slides/Foss/presentation.h>
using namespace Aspose::Slides::Foss;
Presentation prs;
auto& shape = prs.slides()[0].shapes().add_auto_shape(
ShapeType::RECTANGLE, 150, 150, 300, 130
);
shape.text_frame()->set_text("Metal Button");
// Blue solid fill
shape.fill_format().set_fill_type(FillType::SOLID);
shape.fill_format().solid_fill_color().set_color(Color::from_argb(255, 20, 70, 160));
// 3D bevel + camera + light + material
auto& tdf = shape.three_d_format();
tdf.bevel_top().set_bevel_type(BevelPresetType::Circle);
tdf.bevel_top().set_width(10);
tdf.bevel_top().set_height(5);
tdf.camera().set_camera_type(CameraPresetType::PerspectiveAbove);
tdf.light_rig().set_light_type(LightRigPresetType::Balanced);
tdf.light_rig().set_direction(LightingDirection::Top);
tdf.set_material(MaterialPresetType::Metal);
tdf.set_depth(20);
prs.save("metal-button.pptx", SaveFormat::PPTX);
Menggabungkan Efek pada Bentuk yang Sama
Bayangan dan pemformatan 3D dapat berdampingan pada satu bentuk, memungkinkan desain “kartu” yang halus:
#include <Aspose/Slides/Foss/presentation.h>
using namespace Aspose::Slides::Foss;
Presentation prs;
auto& shape = prs.slides()[0].shapes().add_auto_shape(
ShapeType::RoundCornerRectangle, 120, 120, 360, 150
);
shape.text_frame()->set_text("Premium Card");
// Fill
shape.fill_format().set_fill_type(FillType::SOLID);
shape.fill_format().solid_fill_color().set_color(Color::from_argb(255, 30, 80, 180));
// 3D bevel
auto& tdf = shape.three_d_format();
tdf.bevel_top().set_bevel_type(BevelPresetType::Circle);
tdf.bevel_top().set_width(8);
tdf.camera().set_camera_type(CameraPresetType::PerspectiveAbove);
tdf.set_material(MaterialPresetType::Plastic);
// Drop shadow
auto& ef = shape.effect_format();
ef.enable_outer_shadow_effect();
ef.outer_shadow_effect().set_blur_radius(14);
ef.outer_shadow_effect().set_direction(270);
ef.outer_shadow_effect().set_distance(8);
ef.outer_shadow_effect().shadow_color().set_color(Color::from_argb(70, 0, 0, 0));
prs.save("premium-card.pptx", SaveFormat::PPTX);
