Pixel Filters?

[Gruuberhans]

Hello everyone :wink:

I need to know if there is a program out there that lets me convert images in basically the same way as the RM2k3-RMXP resource converter does. As most of you probably know, it resizes images using a filter called super2xqual (or something like that :huh. By using this filter in the program, the images end up bigger (for use in rmxp) but the pixels are not bigger.
Open the spoiler to see an example.

What i need is a program that can convert ANY picture, making it 200% bigger, using a filter like the super2xqual in the rm2k3-rmxp converter. The reason why i can't just use this program instead, is because it's very unpractical to use since I need an rm2k3 project folder in order to convert it's resources to bigger format.

Besides, when i tried to convert a picture that i put in the rm2k3 project's "pictures" folder, it seemed like the picture was too large. I suppose i'd have to use pictures that fit into the rm2k3's 320x240 pixel screen, which is completely out of purpose. I mean, its actually rmxp resources i wish make bigger.

If anyone can help me with this, i will be very happy :grin:
If not, I'll go eat some cookies. :down:

These are called interpolating algorithms, some of the popular ones include 2xsai, super2xsai and supereagle (in fact you can find all three options in many emulators).  I don't know of any independent programs that will perform these algorithms on a group of images; usually they're implemented as part of a more general-use piece of software.  I recommend looking for a plugin or filter for your graphics app of choice and then setting up batch processing if the software allows it.  I remember running into a script that does this in real time as you play the game in RMXP but I also remember it being very slow; I'm not sure you could find it anymore.  RMXP also has a built in interpolator for running at higher resolutions but it tends to be blurry.

I have to warn you though you will probably get mixed results, especially with sprites, and large palettes.  As arduous as it sounds it's much better to do the upconversion by hand, it preserves the clean pixelled look that most players and game creators insist on.

Go for a straight 2x with NO FILTER, as long as its consistent with all the graphics. Trust me, as a pixel artist, it looks MUCH NICER.

@Nphyx: Thank you, that was very helpful. (I knew about the emulator filters though.)
How excatly do i use this built in resolution interpolator in rmxp? just need to test.

@missingno/Despain(whatever): I suppose you are right about the filter thing. btw, do YOU know how to use the resolution interpolator in rmxp? even though its blurry ot whatever, it would look better when i wanted to zoom in slightly.

Looking back at RMXP I might have been wrong about the filter, as I can't find anything to do with it - I may have been thinking of the way it looks in fullscreen mode, which may be a product of my laptop video card rather than the software   I have seen demos of a smoothing filter before but like I said I couldn't tell you where to find them, I'm talking maybe a year and a half ago.  Try looking in the scripting forums.

@Nphyx: Yes, i think it's your laptop. Most laptops these days have that feature.
