If you're using MorphOS, why on earth you wouldn't use included ShowGirls software? It's just the best and fastest software for these kinds of convertions and editing. Free, already installed and compatible too . You can select resizing filter (for example Lanczos does good quality) and do batch converts etc.

I didn't realize Show Girls did that. I'm just used to thinking of it as a Comic Book Viewer.

Will test and compare results.

BTW, I'm not going for speed, I'm going for image quality and preservation.

I now have all the suggestions made above installed on my MorphOS machine.

The results...

Show Girls steals the show by a long shot!

Not only does it support nearly every format under the sun, it also seems to have the best quality preservation when reducing the size of images.

At first the image becomes blurry as one would expect, but once I run the Sharpen feature on the shrunk image, it almost looks as good as the original.

The only faults I see with Show Girls at the moment is the fact that it does not allow for Palette loading and saving, plus it is not always clear what format I am saving in.

When I hit Save, I can choose the format, and I suppose I just change the extension when saving, but when I choose Save As, I don't get to select the format. Also it does not seem to support saving in BMP, which forces me to return to my Windows machine to change the format so that I can apply the Palette I need for DOOM, and save it again.

Is the author of Show Girls still working on this?

Sorry to break in but.. just before I quit the Amiga scene in 2001 or something like that, I was using an excellent Image/Video Converter program. Unfortunately, I dont remember how it was called.. Ive checked Aminet but found nothing like it. I think it used PPC to speed up things and I remember it had a good looking GUI. Can someone point me in the right direction?

Also, @Cammy, I think you mentioned before that Photoshop 4 was the last 68K Photoshop but I remember when I Google'd around for this information myself, I found a page that said the very first editions of Photoshop 5 ran on 68k processors, too. Can you confirm this? If not, can you tell me where I can find Photoshop 4?

Default Re: Image Size Reduction Software

for "automated" image processing I still like ports of commandline tools like imagemagick. a bit bulky for amiga apps, but very powerful.

here's an image i generated back in 2000 on an a1200/030 and vmm (needs ~110mb of ram for the raw 24 bit data)

Quote:
It was created on an a1200/030 with 10 meg of ram and 1gig of
virtual memory using the latest version of the great
image manipulation software ImageMagick.
readme: http://aminet.net/package/pix/misc/ExoMontage-L
the image: http://aminet.net/pix/misc/ExoMontage-L.jpg

(warning - 11mb jpg - ~ 2000px x 18000px)

not a sensible thing to do really, but it was a sort of experiment, and the final result is quite nice to look at. i should think the same image could be generated on a modern pc in a few seconds/mins ;-)

I'm not one who would expect that. Quite the opposite.
Scaling up, sure, because it's manufacturing detail that just isn't there in the original. But I thought you were scaling down.

I think you may find that Photoshop 5 was PPC-only, but it was the last version to work with MacOS 7, perhaps that's where the confusion comes from. I don't think linking to Photoshop on here is a good idea, but if you Google search for Macintosh Garden, they have it, and they have thousands of other Mac software titles and games to download. Get Photoshop 4 and the 4.0.1 update and try it out, it runs pretty well on my A1200 and A600.

I am scaling down. I'll try to post some "before and after" examples tomorrow.

Maybe we can have a competition and see who can come up with the best results.

Funny, I was thinking when you started the thread it might be wise to upload one of the source images somewhere and state the final size you needed, just for that purpose.

Why don't you do the resizing in Windows as well? Personally I use IrfanView which is a small and fast image viewer that can also be used for manipulating images in various ways. It also includes the Lanczos filter for resizing.

Looks interesting Cammy, guess I have to check out this program.

The best software I found for resizing in Windows was Fotosizer, but...

I prefer to work under Windows as little as possible. It's bad enough that all my mapping and Wad editing needs must be done there.

Default Re: Image Size Reduction Software

Alright, here are a few examples of what I'm working with. I have provided to ZIP files, one contains screen shots of some of the models I'm trying to shrink down and use, and the other contains a texture of a crate in it's original form, it's shrank form, it's shrank and sharpened form, and at long last shrank with new palette(s) applied.

The textures for the most part are not problematic. I am pretty happy with the results, though I noticed that once I apply the Palette's that some of the colors bleed. In the case of the file with the DOOM Palette, I already cleaned it up, but I have not touched to colors on the one with the Dark Forces Palette, so you can see what I'm talking about on that one.

As for the sprites, if you compare Sentry.BMP with Sentry.PNG you can see how horrible the images begin to look once shrank. If anyone can manage to shrink any of these models down without loosing so much detail, then PLEASE by all means, let me know how you do it!

For the note, small sprites like the Sentry need to be shrank down to something like 42x42 pixels, where as the the Storm Troopers need to fit in a pixel range of something like 45x56 (width height). As for the Mech1, it will need to fit within a pixel ratio of 50x70 (width x height).

EDIT: I can not upload anything here but the Crates after they have been shrank and treated. Amiga.org's file size limit is WAY to low!!!

Going to have to upload the rest to my page then come back and link to them. Grrr. :/

Default Re: Image Size Reduction Software

your included Sentry.png was a little bigger (50x52).

original


yours


some resizes with imagemagick (that I have handy on this pc)

(Adaptive Resize)


(resize - point filter)


(resize - Lagrange order 3 filter)


(resize - Lagrange order 4 filter)


(resize - lanczos filter)


(resize - mitchell)


there are other filters / options to scale too http://www.imagemagick.org/Usage/resize/ and you could do other processing to improve it

I'll have to look at those at home, my parent's computer screen is too dark.

But thank you for having a look, I'm eager to see what they look like on a good screen!

As for the reason mine was larger. It's because that's as small as I could get it before it looked like utter and total crap. In fact I still think my end result looks pretty crappy, I had one that looked a tad bit better, but forgot to include it.

Anyhow, if you could possibly shrink down one of the other models to fit within the specs I mentioned, I'll REALLY be impressed! I always ended up with a bunch of blocks that hardly resembled the original model.

On that note, I may have to take smaller screen shots of the models to begin with. That has helped in the past, but again, zooming out the model results in less detail.

Once you have viewed em on a decent screen, let me know if you prefer any of my scaling ones from yours and if so ill do the resize (please give me a list of sizes for each image as I wasnt sure about the size you wanted for some of them)

Cheers.

Hmm... You have the format list in the Save Image window. It just saves in the selected format with both Save and Save As buttons. As usual (with Amiga), the file extension doesn't matter.

Looks like I did end up sharing my best result after all. I just needed to replace the redness on the edges with more black and Grays.

I thank you for the offer, but what I'm looking to do here is give time for a few people to experiment and submit their results. Then if someone can come up with something that is a step above the rest, I'd like then to share their methods so I can learn from them.
