You basically just use the original (preferably resized) image but before rendering it on screen, you add the information where you want it to be. The 'Change the way you make your program' part is the most sensible to me. Change the type of image: do you really need photo-realistic pictures?.Use tools like pngquant to achieve lossy compression in png, resize your original image, etc.'Blend' less so that the codec does not remove it.Now I think that you understand that what you are trying to keep is precisely what JPEG was designed to remove first. It does so because that's what allows to keep the highest quality while increasing the compression ratio. JPEG is lossy and achieves such high compression ratios by removing the visual feature that are the hardest for the human eye to differentiate: similar colors, similar brightness, highly localized data, etc. The color and brightness of this number closely matches the Secondly, what you are asking cannot be trivially done the way you want it done. Based on these data, I would first recommend to resize your image as such a size is simply insane for a point&click game. So it seems that your image is either pure random noise OR something went wrong and you did not get a proper PNG.

That means that your image should be unchanged but the price for complicated pictures is a higher memory footprint. Thanks in advance, if you need to see the file then I can provide a link to it (at 250MB size or 50MB size).įirst of all, TIF/PNG is already compressed. Is there anything I can do to compress the image while still preserving the integrity of the number? The number only encompasses a few pixels, but the addition of this small data has increased the file size 25x. An uncompressed save file (TIF/PNG) reaches up to 250MB. This maximum compressed JPEG increased the file size to 50MB even though the original was just 11MB. Now, when I went to save this image, the compression destroyed the hidden number, even at JPEG 12/Maximum. The color and brightness of this number closely matches the surrounding pixels so that it blends in. I had a very small image within this (a pixel-sized number). I downloaded an 11MB compressed photo from the internet which is 85MP in size (14000 x 6000 pixels).

Here's my problem: I am creating a game where players have to search for a hidden detail within the overall image. Forgive me if this is the wrong site for this question.
