I am trying to import an image and Scribus is changing the image dramatically!
I am importing an file showing grasses (made with a stamp in photoshop) and the first time it showed all the grass as being bright ORANGE (it is green in reality). I went back to the file in photoshop, flattened it, saved it as tiff and re-imported it, only this time it is missing two of the layers- i.e. the bottom half!
Every time I go back to photoshop, the image is exactly as it should be, green and complete.
Importing images should be a no-brainer, something I have done a million times so I am not sure where I am going wrong...
hi karela
i don't see a way to help without access to your document. (.sla and placed image file)

Here is the tiff that I imported as well as what it currently looks like in Scribus. It should be a green gradient down to the logos. (which are a bit messy because they are still a work in progress).

can't seem to upload a tiff, so here is a jpeg to show what it should look like!

hi karela
you uploaded the .sla file – but none of the images...
utnik
edit: with the .jpg file it looks ok. see screenshot!

Our replies must have crossed! Sorry, it took me a while to figure out that I couldn't upload the actual image because it was a .tiff.
you could upload .tiff files as .zip archives...
utnik
Is it clear from the jpeg or would it be better to upload the tiff as a zip?
hi karela
take a look at my screenshot and tell me what's wrong. i don't see anything unusual (except of the fact that the .jpg comes with a resolution as low as 34 ppi...)
utnik
Utnik, your screenshot is beautiful....but does it look anything like what you see in my .sla file?
The low resolution is because before I noticed that it was not possible to upload .tiffs I thought that the problem was that my file was too large, so I made it very low resolution.
this is a screenshot of your .sla file with the placed (and enlarged) .jpg file – i don't have any of the other images...
for a real check of the issue you could upload the whole project ('file' → 'collect for output' then compress the whole folder to a .zip file...)
utnik
Collected for output and zipped. I took off the logos because they made it too heavy.

hi karela
still no other problem than the low resolution. at least i'm not able to spot it – sorry!

Utnik, on the screen shot that you sent before with the jpeg and the one you sent now there is a huge difference between the two files- the one with the jpeg shows the image accurately and the one with the tiff has the bottom layers missing (the solid green gradient).
Here is the compressed tiff I am trying to import.

yes, there is a difference. but it's your file...
even in gimp or photoshop i can't find different layers, but an alpha channel wich cuts the bottom part – what do you expect?
(the screenshot shows photoshop cs4.)

I am not so familiar on how alpha channels work, I followed an online tutorial for smoothing edges and this was one of the directions (the making of an alpha channel, not the cutting off the bottom part of the image :)).
The gradient layer is/was on top of the other ones, though (I flattened the image when I saved it as a tiff) and the image shows the gradient layer.
What would my options be?
1) Use the jpeg file since it shows the gradient?
2) Add a gradient in Scribus?
3) Attempt to expand the alpha channel to include the bottom half?
hi karela
editing the alpha channel is a good option.
as long as it's the background of your file, you could delete the alpha channel – you don't really need it.
utnik
The reason the JPEG works is that JPEG don't support transparency (and alpha channel is transparency).
So the JPEG only contains, R, G and B, while the TIFF contains R, G, B and A.
A very good tips when something looks different in two programs: Try with a third program!
Alpha channel deleted and problem solved. Thanks so much for your help!
