I must point out there was a post sometime back with regards to problems with some images acquired via netwebget. If I remember correctly they where greyscale JPG's upon inspection. I will have to see if the post is still about on the forum.

I want to know more about these banana threads and update fairies. 

Don't upset the fairies, they may visit your pc & start deleting code also

Personally any of the pre-hdmi non HD I would route to my CRT television. A lot of hard work went into the design of the lower resolution gfx on quite a few games of the era relying on the blurriness of a CRT to give the illusion of more colours etc.

Even with the filters you get on emulators it's still lacking that "Look" for want of a better word on todays pixel perfect LCD's.

Me thinks, its was the original thread starter (not sure who that started the thread)?

PS. If its was the original thread starter, that deleted it, im do thinks we should respect that.

It is possible as I just had a look at some topics I started off & there is a button at the bottom with "Remove Topic" on it which doesn't appear on any others that where not started by me.

Part of me respects it, but part of me doesn't. The part that doesn't is purely from the point of view there was some very good points raised which may not see the light of day again due to them being responses & not just general posts.

It's been a very long time since I have Administered or Moderated an SMS forum & vaguely remember there are logs that can be viewed. However how far up the chain of command you have to be to view them & even if it was a SMS or a PHPbb forum I honestly do not recall.

Can a person that starts a new thread delete it seeing as they created it?, I know on some forum software you can but what ones I'm unsure of.

Just done the same tests again but with BMP's & PNG's & witnessed exactly the same memory pattern as before.

I must mention that all tests where done with debug disabled so as to remove that from being a possible cause.

Pagefile usage in my case may be down to using 32bit windows 7 with 2GB of ram as my main machine is down at the moment. However it has 1.4GB free after booting windows & startup processes complete so more than enough free for the test program which shouldn't use more than 400MB inc the images.

Perhaps the mysterious GLB update fairies have forum control also

GLB being a 32bit program did cross my mind but I discounted it mainly because each image is around 37MB in raw RGBA for, multiply that by 38 images equals 1.4GB of space so under the 2GB win32 limit imposed on by most win32 apps.

However I done a simple test listed to below just to see memory usage out of curiosity & saw things I didn't really expect to see. The images loaded are the size the filename says, so 1024k is a 1024x1024 image etc & the images are just simply rendered clouds from photoshop to give some randomness to them.

The program starts using 12,916KB of ram before loading the 1st image, then jumps to 25,536 after image has loaded (1024k one). The next image uses 58k then drops to 38K but pagefile size increases, then 142K ram, 168K ram then finally 563K. After every LOADSPRITE the ram increases as stated earlier but as soon as the image is displayed on screen it drops down to 38K & pagefile usage increases. At one point (on the last image) the page file increases to over 1GB higher before running the program then drops down just over 320MB from initial.

All the images combined add up to around 376MB in raw RGBA form yet system ram reports only 38MB used, adding the page file increase gets me around the 376MB as expected.

What causes the big ram jump in the 1st place I have no idea other than possible jpg decompression, also why the pagefile usage is beyond me but expect nothing less from M$ & their never ending addiction to using the pagefile.

What are the image dimensions? for example a HD 1920x1080 works out about 8MB of memory usage, where as a 12MP digital camera image takes up 47MB.

Jpeg file sizes can be misleading, for example a 2MB jpeg image could have a low resolution & low compression or have a high resolution with high compression.

Perhaps the decompression of the jpg may be affecting things?

Lee.

Looking awesome there Erico, keep it up

Lee

Thanks for letting us know  .

I take it the previous version 12 should be uninstalled & the new one downloaded from the link at the top of the forum as the update feature doesn't seem to find anything.

Lee

Funnily enough I use Fireworks as well, because it's designed for web graphics it handles bitmaps far more efficiently than Photoshop etc (which to be fair are more geared to photo editing & so on). I love the slice tools, symbols & animation side of things which combined with styles allows you to generate consistency for whatever you are working on.

I use CS6 as I have the Adobe Suite but even older versions are more than capable & well worth a purchase. I think you should be able to pick up an older version for very little money & it might even be cheaper than some of the current bitmap tools available but with a lot more powerful toolset.

@ Mentalthink : I think Mr.T was referring to the early days of the A600 in which yes there was some compatibility problems with older software (same problem that the A500+ suffered along with the A1200). Not only that the lack of numeric pad cut off the use of some games that made use of it.

@MrPlow : I did mention grafx2 in my previous post & like I said while it says its a tribute/inspired by Dpaint there's just something about it that doesn't feel quite right to me. Not a fault of the program but more a personal "Me" thing
