Thank you. My node need some calculated image to be cached for later use, which is not very likely in other node, but highly useful in my node design. The image ususally will be reuse for three times. And my other question followed. How can I tell one image from other? How to know which one is computed and should be gotten from cache and which one is not. It there any of knowing the CompBuf containing the same image? Maybe a digest is needed. Then I find md5 is used in imbuf's internal code which is not available for external use. What shall I do?
