GIMP trouble ORA

[ascanius]

I was wondering if anyone else has had trouble with GIMP opening .ora files. I can open an 89MB file for my continent map but for some reason when I try to open another 34MB file for my world map GIMP just hangs. I can open it so long as I have only one or two layers anything greater and it hangs but for the larger file I can have up 10 layers before it hangs for a few minutes, the smaller file hangs for hours.

is that the Adobe Photoshop open? raster

if so use a different format to transfer from Photoshop to gimp

it was meant as a replacement of the very closed source psd and the gimp devs have to REVERSE ENGINEER psd

try using the Krita editor


the OLD gimp2.6 needed a external plugin
2.8 has it built in , but just basics

The ora i'm talking about is the open raster archive. I've thought about another format but the .ora alows me to open the image with layers. Frankly i'm nont that up to date on image formats, save for png.

I use krita right now then transfer to gimp for touchups and all path work, Krita has a 72 px path bug so the paths show up way to big.

See the thing I don't understand is the map for my continent is 110mb, 12000x6000 at 300ppi with 10 layers and (I tried 600ppi but it's a little too much) I can export it to .ora and open it in GIMP, the load is a little slow but it gets there and everything works. my other map, is 2.4 mb 12000X12000 at 300 and I can only open the .ora file if I have 2 or less layers, GIMP just keeps loading and loading for 30 min to an hour.

if you are saving to ora using gimp

use the gimp internal format
.xcf

as of 2.8
if you only hit < control>+<s> that is the format gimp will save in ( the OLD gimp save shortcut)

to use other formats you have to "export" the image


the Gimp dose NOT care ( nor dose photoshop) about "300ppi "

pixels per inch or Dots per inch
ONLY!!!! matter for PRINTING!!!! ( scanners do not even need that )

your printer is the only thing that NEEDS dpi or ppi

a image editor has NO need for that information and dose not really need it
the only time you need to adjust the PPI is for importing a PDF or SVG or in printing the image .

12000x6000 PIXELS is the only thing you need to know
the width and height ( 8bit/layer is default)

that ( 72 px ) is the default screen resolution for a OLD!!! 600x800 CRT vacuum tube screen that is 8in.x 11in.

Are there any good gimp tutorials? I want to convert from hand drawn to digital.

You could also try tiff if you need a little more portability. Tiff's specification is loose enough, though, that if you're doing something particularly strange it might not open in some programs.

Norseword: Try searching the Tutorials forum here for "Gimp." You'll find a lot of them. You can search specific forums using the Advanced Search instead of just typing in the basic search box.

Thanks, I'll give it a try. I don't know that much about the best formats to use so... I just need something that will allow me to open in gimp so I can do path work without loss of information and layers.
