I am new to free image. I am working on scientific application in which at a times I need to load a high resolution image into the application. I am using OpenGL as a grpahics displaying API. I need to know, whether I can do the following using FreeImage.
I need rescaling to improve the rendering speed. As the user zooms in, more details can be fetched from the temporary file and displayed. Is there any such facility in FreeImage or I have to manually do it? Any example or link to suitable example will be appreciated.
Short answer - NO. Look at VIPS or ImageMagic.
Both support larger-then-RAM images. FreeImage does not.
