This function sets a context's drawing scale.

Syntax

• void SetScale(float x, float y)

Parameters

• x: the x component of the scale to set.
• y: the y component of the scale to set.

Example

#include "Leadwerks.h"

using namespace Leadwerks;

int main(int argc, const char *argv[])
{
        Leadwerks::Window* window = Leadwerks::Window::Create();
        Context* context = Context::Create(window);
        Font* font = Font::Load("Fonts/Arial.ttf",48);
        context->SetFont(font);

        while (true)
        {
                if (window->Closed() || window->KeyHit(Key::Escape)) break;

                Leadwerks::Leadwerks::Time::Update();

                float a = Leadwerks::Time::GetCurrent() * 0.1;

                context->SetColor(0.0, 0.0, 1.0);
                context->Clear();

                //Draw some text centered on the screen
                std::string text = "Hello!";

                float x = context->GetWidth() / 2;
                float y = context->GetHeight() / 2;

                float w = font->GetTextWidth(text);
                float h = font->GetHeight();

                float scale = Math::Sin(a)*0.5 + 1.0;

                context->SetRotation(a);
                context->SetScale(scale, scale);
                context->SetTranslation(-(Math::Cos(a)*w - Math::Sin(a)*h) / 2.0 * scale, (-Math::Sin(a)*w - Math::Cos(a)*h) / 2.0 * scale);

                context->SetBlendMode(Blend::Alpha);
                context->SetColor(1.0, 1.0, 1.0);
                context->DrawText(text, x, y);
                context->SetBlendMode(Blend::Solid);

                context->Sync();
        }
        return 0;
