  Open a file in Gimp from the command line
Posted by: dataweary - 01-04-2019, 05:07 AM - Forum: General questions - Replies (3)

Hi,

I'd like to open a file in Gimp as part of a shell script on OS X Sierra (I use the Partha Bagchi build).

If Gimp is not launched, it works perfectly with the following command:

open McGimp-2.10.8.app --args ~/Documents/Archive/scanpic.jpg

But I don't know how to open a file with the script when Gimp is already launched. In this case, Gimp comes to the forefront but the file is not opened.

Any idea how to achieve that?

  hatch image
Posted by: denzjos - 01-03-2019, 01:55 PM - Forum: Tutorials and tips - Replies (4)

When I have to hatch a technical drawing, I have to draw a line, copy the layer and move the layer (multiple times). I thought a macro creator would be usefull and I've tried the Pulovers Macro Creator (open source). I've made a macro and it is satisfying. Before starting the macro one have to make sure the copy layer is tranparent and set the thichness of the pencil to 1.Then start with an empty image.The macro draw a new image, draw a 45 degree line, copy the layer and move it to the left. This is done up to 150 times. After the macro is ended, all one have to do is make the backgrond layer invisible and merge the visible layers (Image / Merge Visisble Layers). One can then copy and paste the transparent layer and then move the pasted layer to the right to fill out the empty space. Then it is advisible to crop the layer (Layer / Layer to Image Size). In attachment, the macro and the result. If the macro give a fault result on your computer, then change the sleep times. The macro is made for a keyboard with a keypad. It is possible that this does not work on a portable. Then change the Numpadx to x(where x is a number / press right mouse button to change) . I've made also a macro that draw lines with Pulovers Macro Creator but copy layers is much faster.   

   

I don't know how to post a file here so I'v made an image of the code :

  exporting pdf vs. jpeg
Posted by: shortmort37 - 01-03-2019, 01:29 AM - Forum: General questions - Replies (3)

I'm attempting to make a banner with two color background, with text containing two different colors - but, with different fonts (in different layers). All told, there are 10 layers, one with zero opacity - I used it as an underlying guide to construct the banner.

When I export it as a jpeg, everything is aligned perfectly - but of course, when you zoom you get the staircasing you expect from a bitmap:

[Image: jpg_banner.jpg]

When I export it as a pdf, it zooms perfectly, again as you would expect from a vector-based image. However, There is some blurring at the border of the two background colors, as if they are blended from misalignment; and there is whitespace at the right and bottom edges. Here is a jpeg snapshot of the pdf, where I've outlined the artifacts:

[Image: pdf_banner.jpg]

When I rendered the pdf, I chose these options:


[Image: export.jpg]

Is there anything I can do differently, to have the pdf render in appearance as the jpeg?

I should add there's issues with font alignment from the various layers. Look at the "!" that trails "HERE". They are different fonts (and different layers) - they align at the base of the text in the jpeg, but not in the pdf.

Is this a bug with GIMP?

Thanks
Dan

  Start up and use Gimp 2.10.8 ver 2 Samj
Posted by: Pat625 - 01-03-2019, 01:02 AM - Forum: Windows - Replies (6)

Downloaded the ver 2 as understood too many problems with the first.   Initial start up OK but as plug ins and scm added more problems.  Start up interrupted by statements of no function known, hit any key to continue and some that hang for a long time before continuing.  Have Demo.exe that appears and must be deleted before continuing.  When start up finally finished, all looks OK, but plugins that were added on first start up only stay until computer turned off.  When Gimp started again, go through all the same start up problems but the added plug ins are not there.  It is though they were never added by using Edit/Preferences/Plugins.  I have not had this problem with any versions of Gimp before.  I have completely erased it, re downloaded repeatedly but continue with this problem.  If the added plug ins are not in the original system and profile folders, they disappear.  This goes also if a subfolder has been added, it disappears also.  They seem to work properly when they are present.  Am I missing some files?

Has anyone else had this problem?  I tried reporting it, had a few replies, but then I had notices that their server would not accept messages from me.  Asked for help but no reply.

Any suggestions?

I am using Windows 10.  64 bit  Have Gimp 2.8.22 reg version still on my computer.  I have installed the Samj Gimp to the desk top to separate it to another directory.

  Filters for Photo Art
Posted by: Paul E. Lehmann - 01-03-2019, 12:03 AM - Forum: Extending the GIMP - Replies (1)

Recently downloaded Gimp 2.10.8 on MAC running High Sierra
Interested in additional filters for converting photos to sketches, water color and oil painting

I do not seem to have all the filters that I have seen on various web pages for doing these sorts of things.  There seems to be more than what came with the download.

Can anyone tell me where to go to get them and how to install.

Thanks

  Adjust and Save a Gradient.
Posted by: rich2005 - 01-02-2019, 02:40 PM - Forum: Tutorials and tips - Replies (1)

Gimp 2.10 gradient tool allows adjusting and editing a gradient on canvas. A great improvement. Saving is simple as well, no need to open up the gradient editor anymore Wink

A short video demo duration 4 minutes.

  Preventing Colour Changes?
Posted by: dancingsquirrel - 01-02-2019, 08:41 AM - Forum: General questions - Replies (1)

I'm creating illustrations from scratch on a transparent background, converting to png, and uploading. When I view my work on my laptop (Windows 10) its fine, but on my phone (Android) some of the colours are whack! Is this likely a problem with my phone settings specifically, or is everyone who sees my work on certain operating systems getting this?  Thanks friends!

  Alpha transparency space in borders for stickers.
Posted by: Tetragram - 01-01-2019, 11:07 PM - Forum: General questions - Replies (16)

Hey Guys. I'm creating stickers, and I want to send to the printer, information that there's a couple of inches of transparency after the edge of the images. I'm making it about 2 to 4 pixels. Something small.

I have the cut out in Gimp, but can't figure out how to do that. 

I have read about the tools and searched the web as well but haven't found an answer. 

Any help is appreciated.

Rainbow Change colour
Posted by: eliassons - 01-01-2019, 08:15 PM - Forum: General questions - Replies (2)

Okay, I have a question.
I have a Picture of a veichle, that I want to change colour of. right now it´s blue, but I want it to "pig-pink". I know how to change the colour, either I do it by making a transparent layer and paint in that(like this video: https://www.youtube.com/watch?v=yfnRntPBS8c ), or I use colour rotation. The problem is, that I can´t paint it with "Pig-pink". If i select that colour it just looks like ordinary pink(see the photo i attatched). I want to paint with the colour i selected. Can someone please help me with how to do?

/eliassons

And if you don´t know "pig-pink" looks, it´s like this: https://www.google.com/search?q=saga+rai...6368416617
