Hint- buy some more ram. - I have edited some 1.8gig images on a PC with 4gig of ram using the gimp, its not that fast- but it was useable.

I know you probably want an sdk that can handle images bigger then your physical memory- but you cant have the best of all worlds. Large images + Low Ram + Fast editing just isnt that possible- unless the operations can be edited on tiles as you suggest. not all func's can be tiled, so probably to save your self some time - buy a 1gig chip.

Hi,

I am not sure if it is suitable to ask this question here. But it makes me crazy for many days.

I am looking for an image SDK which can process an image of size, for example, more than 1GB. I tried to open an image file(*.tiff) of size 800MB GIMP on my computer, WinXP, PIV 2.4GHZ, and 1GB memory. It is too slow. It is impossible to edit it. Since tiled tiff can be used to store/process large image, I am wondering if GIMP makes use of it. If not, can anyone do me a favor to let me know what SDK I can use?
Sorry for the spam

Thanks a million in advance

First of all, sorry the bad english, I' m a brazilian GIMPER.

I have an idea about a new plugin that could help you.

I gonna write an example of the functions:

Two months ago, I was working in a Panoramica Job manually (following the "Grokking the GIMP" book). The file was bigger then my mail sent-limit, then I smalled the image size by the half.

After, at home, I did make all the job and get some satisfactory result. But, the small size of the image makes me redo all the work in the original file, step by step, just changing the sizes of the filters, selections and editions.

Well, the plugin I thought, should start with a window indicating the actual size and resolution of the image, and asking the size and resolution we would like to work with.

Then the original image and all the commands should be saved (in memory, external file GIMP file), while we are using they in a smallest image.

At the end, the plugin "translates" all the commands to the original size and transform the original size file.

The advantage of this plugin? Faster image edition.

I think a plugin like this could help you too.

This is just an idea, I don' t know "C program language", but I' m interessed in aid this development. I don' t know how to suggest this to the developers, but I think this plugin could be very useful for a lot of GIMP users.

That's all Folks !!!

Unfortunatelly, I don't know about your specific request (sincerely I don´t know what is a SDK :) )

Anyway, if someone knows about how can I do ideas contribuitions for GIMP, please tell me.

Hi Dalai,

Good point! However I am a newbie in image processing. I don't know how diffcult to develop such a plugin. Maybe an existing SDK can help me more because our project is very urgent. Do you know any existing SDK for large image processing?

Thanks

You could try http://www.vips.ecs.soton.ac.uk/index.php . I have no idea how well it works on windows, but at least there are prebuilt binaries so you could try it out.

You could use something like VIPS to chop your scans into manageable pieces, retouch the tiles one at a time in gimp, and then use VIPS to recombine them again.

You could also consider 64-bit gimp. I imagine you could go over the 2GB limit with a 64-bit build, though I've never tried it.

VIPS would be OK for the scanner software. I've built painting scanners which make 10 GB images using VIPS to do the automatic image assembly, correction and calibration.

Thanks. I tried it. However, it is very bad at retouching photographs as shown on the website of VIPS. I want to develop a application for a scanner, which should be able to let user edit the images.
