  Help - can't get Mathmap and GMIC to work together
Posted by: paulfh - 07-17-2017, 09:36 AM - Forum: Windows - Replies (2)

Hi, after accidentally (silly I know) trashing my .gimp-2.8 folder I am unable to get two of my favourite and most used plugins to work together. These are Mathmap and GMIC. If I install only one or the other they work. But if I install them both only the latterly installed plugin works.

I *think* I have narrowed the problem down to the libfftw3-3.dll that both are dependent on. I've also noticed that the .dll for Mathmap is nearly twice the size as the one for GMIC.

I have had those two working together before so I'm at a loss as to why the won't do so now. Any ideas folks?

I'm on Windows by the way.

  Perspective Tool
Posted by: Pat625 - 07-15-2017, 05:54 AM - Forum: General questions - Replies (8)

I have difficulty using the perspective tool.  After adjusting one side, I try to adjust the other side but the first one moves.  Is there a way to anchor the corners so you can go to another one without the first one moving?

Thanks in advance for any advice.

  Making white area of a picture transparent.
Posted by: tm2383 - 07-15-2017, 12:09 AM - Forum: General questions - Replies (1)

Hi, 
I practice ididology and would like to be able to superimpose the chart below over the iris of the eye on a separate layer. For this to work, I need to remove the white and make this section of the iridology chart see through, but leave the black lines intact. How do I do this in Gimp? Also, is there anyway to change the black to another colour, such as yellow, to make the black lines more visible when superimposed on an iris image. Thanks in advance !

  Removing & Replacing
Posted by: James82 - 07-14-2017, 12:25 PM - Forum: General questions - Replies (6)

As a very new newbie might I have some advice on removing the title from the image on a book cover and replacing it with the general background mixture of cloud and sky? 

Might there be a You Tube clip that could help? 

Many thanks.

Hi all.
First post here and new to Gimp. I would like to create a logo in the form of a sphere, that has a piece missing from it. Think of it in 2d form as a circle with a piece missing (pie chart style). Adding to that, a name across the sphere too.
Any info on the how to for this would be greatly appreciated.
Cheers.

  Retaining colours after colour to alpha
Posted by: motorsportfurniture - 07-12-2017, 03:46 PM - Forum: General questions - Replies (3)

Please see attached image.

I have roughly cropped the driver - inverted the selection, then cut, to delete the background. Then I have feathered the edges and then 'Colour to Alpha' to completely get rid of a background, so I can put the cropped part on any colour.

However my problem is, obviously all the white / very light areas of the cropped selection are also deleted because my colour to alpha was to remove white. So if i place on a dark backround, it shows through.

How do I retain 'ALL' the original colours from the cropped selection but still have no background.

I'm sure there's a much easier way but I'm new at this so apologies!

Any advice appreciated!

Thanks

  Cloth texture in three easy steps
Posted by: Ofnuts - 07-12-2017, 05:54 AM - Forum: Tutorials and tips - Replies (2)

1) Using the Blend tool (shape: bilinear, repeat: triangular shape), fill a layer with thin stripes (3-4 pixels, you can zoom to help). These stripes can have a slant (in practice it's best if they have a random angle, this make the result look less regular):

   

2) Duplicate the layer and rotate it by 90% (you can also create a second layer, possibly with other colors, and create stripes roughly perpendicular to the first one on it).

3) Set the top layer to "Dissolve" mode and set its opacity to 50%

  remove keystoning from painting photos
Posted by: broker12 - 07-11-2017, 01:19 PM - Forum: General questions - Replies (6)

I would like to know if GIMP has this feature . . . in photo shop, it' is called removing keystoning from photos of paintings. That's not a genuine name. It's how others talk about this feature.

What removing keystoning does is allow you to straighten up the edges off a photo of a painting. Usually, it is quite difficult to set up a painting so that the photo of it is perfectly square. In photoshop, this is the procedure for removing/straightening the edges of the photo of the painting:

Removing keystoning from a photographed rectangular work is not difficult in Photoshop. Use the Crop tool to get within a quarter inch of your painting, (but not too close). With the NAVIGATOR, ZOOM IN to at least 100%, or much more. Now SELECT/SELECT ALL. Go to EDIT/TRANSFORM/DISTORT. You will find in the corners, 4 small box buttons. Drag each of these out one at a time until you get each corner of your painting pulled tight to the corners of the image file frame. Press ENTER or RETURN (Mac), to accept these changes. Any perspective distortion present in the original image will be corrected now.

To get the proportions or aspect ratio of your painting back on track, take measurements of your original painting, go to IMAGE/IMAGE SIZE, disable the CONSTRAIN PROPORTIONS checkbox, so you can alter them. Now type into the height and width dimension boxes, the actual measurements of your painting. Since this may increase your file size to something overwhelming, you can reduce the pixels per inch to something much smaller than 300dpi to something like 96 dpi, or 72 dpi. Press OK, and your painting will be flat, square, true proportioned, and looking good! Remember to go back and reset the CONSTRAIN PROPORTIONS checkbox in IMAGE SIZE, for the next time you use that function

If anyone knows how to do this in GIMP, please let me know . . . Thanks
