Dear Forum,

I need to halve the resolution of about sixty .png pictures, from 600dpi to 300dpi, preserving their Alpha Channel (transparent background).

I tried with XnView, which provides a very complete batch conversion/editing tool, but, ulnluckily, in the new 300dpi files Alpha is suppressed.

What can I do?

Can GIMP work on these several files this way, with a unique batch action?

Thank you.

Hi Experts,

Where can I download the Focus Blur plugin for Gimp 2.8.22 (Windows 10), and how do I install it?

Thanks in advance for your help.

Cheers.

How can I remove personal data from a .jpg file? When I export a jpg picture I do not see an extra window
where I can handle this.

Hello everyone, I really liked Gimp 2.9.6 but I really need this plugin, would anyone know how to make it work in the new gimp?

follow the link of the plugin:
http://registry.gimp.org/node/33

Updated my Gimp 2.9.7 yesterday and looking at various functions. 

I remarked earlier on the Blend (gradient) tool. Draw and adjust the endpoints on the canvas, also bring up the editor for more adjustment.

Now further enhancements, 

A floating dialogue with the position and colour of the active end-point.



Grayed-out in the screenshot but if you know what you want, there is an instant mode.


As well as bring up the gradient editor dock, the gradient stops can be adjusted on canvas.



Stops: moved, deleted, color changed.

   
I have a feeling there will be no solution to this other than to decrease the my screen resolution.

I just got a new laptop and installed gimp the problem is the tool icons are miniscule. Is there any other way to solve this? Thanks!

I was going to include a screenshot to demonstrate just how bad the issue is but this site apparently only allows linking to websites and I am not sure how to post that way. I did discover an attachment button though, so ... yeah.

Thanks in advance for any help. 

[attachment=826][attachment=825][attachment=825][attachment=823][attachment=823]Got Gimp last week and been trying three days now via Utube, Google, etc, to make believable face swap--no luck. So far have isolated faces and matched their size but am stuck!!! All tutorials seem to omit simple steps--correct keys, etc--and can't get anywhere... Anyone here who will help a moron like me? Please??!!  PS: Have faces matched well with angles and pixels, size... just stuck there....[attachment=823][attachment=822][attachment=823]     [attachment=823][attachment=827][attachment=827] Update. Here's the three images. The two portraits are closely resized, and end goal is a clean swap of "sunglass" portrait onto full body/background shot, w/the face tone matching the arms. Any help would be much appreciated....

Hi

I'd like to use a gradient as an alpha channel , so that for instance an image fades to transparent. 
I made a white->black radial gradient and did 'color->color to alpha' but now am stumped as to how to make this into the alpha channel for another image - I dont seem to be able to paste it as an alpha channel from 'Channels' which seemed like the most logical thing to do , and if I add this as a layer to another image and then merge down I lose the gradient alpha.
Maybe I need to use a mask?

and won't let me resize the printing larger (it will let me go smaller)

I imported a PDF into gimp, choosing the option to import each page as a layer. 

I manually typed a PPI of 600. The previous imports into gimp using the automatic PPI of 100 were low res and blurry - much less clear than Acrobat Reader showed them. This new import appeared to retain sharpness that the 100PPI dropped.

I expanded the canvas and distributed the layers (pages) of the PDF, so now I have an image 8.5 inches across the top and (number of pages times 11.5 inches) down.

When I try to print this, gimp tries to print the whole thing on one 8.5 by 11 inch sheet. I got similar results with a 2 page or a 12 page import.

I cannot increase the print size on the print dialog (image properties tab)- the maximum it'll go is 100.9mm by 250mm. I can type in a larger size but when the caret leaves the field it immediately snaps back down. Gimp does let me reduce the size.

under image-> print size dialog it lets me change print size but when I actually go to print the size has returned to the maximum of 100x250mm on the image properties tab and again I can only decrease the size, not increase it. 


I'm using version 2.8.22.

Hello
I am using GIMP and INKSCAPE to do cloth personalisation and up-cycling, on LINUX 16.04 Xubuntu.
I have a picture of a stitch garment in 2 colours. (see attachement for a picture with reduced definition)
I would like to get a path from this picture in order to use it in INKSCAPE.
I have tried to use colour selection then selection to path; But the path contains some 35000 nodes and when open in INKSCAPE it never comes back.

I have a high picture definition. I thought about reducing the definition but I am afraid to get "staircases" instead of curves. Do you have any suggestion on howx I could reduce the number of nodes. Is there a modificcation of the image before doing the selection which could help. The "contiguous coulor "selection does not work any better. So any help would be welcomed.
