Detailed Description

A type of ImagePixelData that stores its image data in an OpenGL framebuffer, allowing a JUCE Image object to wrap a framebuffer.

By creating an Image from an instance of an OpenGLFrameBufferImage, you can then use a Graphics object to draw into the framebuffer using normal JUCE 2D operations.

◆ convert()

virtual Image juce::ImageType::convert ( const Image & source ) const

virtualinherited

Returns an image which is a copy of the source image, but using this type of storage mechanism.

For example, to make sure that an image is stored in-memory, you could use:

myImage = SoftwareImageType().convert (myImage);

juce::ImageType::convert

virtual Image convert(const Image &source) const

Returns an image which is a copy of the source image, but using this type of storage mechanism.

juce::SoftwareImageType

An image storage type which holds the pixels in-memory as a simple block of values.
