  Gimp 2.8.14 - Scanning Photos Using ISCAN - Resolution
Posted by: steveTu - Today 09:02 - Replies (1)

I have just acquired an Epson V550 scanner and have set up the drivers etc to run with gimp. All seems to be working fine. The question now is - how do I get the 'best' resolution results without breaking the bank on size?
I can scan at various resolutions in DPI - and the scanner allows up to 6400 DPI, but from what I can gather, scanning at much more than 300DPI (depending on what the planned use is - and mine in just viewing and maybe printing the images at max as A4 type size). Typically the photos I have are 6"x4".

Looking at it, I have the Gimp set up at 300x300PPI, and if I scan at 600DPI (so 3600x2400?) it seems to give a fair representation that seems fairly expandable. On saving I have then used PNG as the lossless format. Would that seem reasonable?

  16 bit per Color GIMP?
Posted by: wmrobins - Jul 26, 2015 03:12 - Replies (2)

A I recall, a few years ago, the GIMP developers were working on a 16 bit per color version of GIMP. What ever happened to it? Is it still being worked on or has it been dropped?

  Editing 2 images at the same time
Posted by: ShieldsA - Jul 24, 2015 13:30 - Replies (8)

We do aerial photo mission and our camera takes 4 band (RGB and C-IR) images. After it is all processed, we have to edit the seam lines were the photos are joined. We first do the RGB and then C-IR images. Then we do the C-IR image, we are basically repeating the same fix.

The question is:
Is there any way we can layer the images so that if we fix the offset on the RGB it will fix the C-IR at the same time? And then separate the layers, it would cut our time in half literally. I tried putting them in a layer but the fix on the top image won’t carry through to the other image.

  GIMP crashes on drawing text box
Posted by: telden - Jul 23, 2015 20:41 - Replies (5)


I am using the Lubuntu 13.10 Saucy Salamander operating system with KDE Plasma 4.13.3 and GIMP 2.8.10. and a Wacom Intuos Pro drawing tablet.

The text function is functioning very erratically as of recently - I don't know how far back, maybe a few weeks? It had been working for the previous year.

Here's the problem. When I have my tablet plugged in via USB and I click on the text icon in the toolbox and, using either a pen or mouse, try to define a text area, no lines get drawn to define the area and the program crashes.

The only way to draw a text box at all is to unplug the Wacom, replug it back in, and then use the mouse to define the text area. Somtimes it will allow the pen to draw it. But eventually it will crash and I have to unplug the drawing tablet again.

This has been happening for days.

I am a non-techie.

Can you tell me what might be the problem and what I need to do to fix it?

Thanks in advance!

  Gimp 2.8.14 - Scaling layers/images - image 'disappears'
Posted by: steveTu - Jul 23, 2015 18:00 - Replies (7)

Using Gimp 2.8.14.
I have successfully created collages - no great deal. Simply opened a new image, set the size as 3000x2400 @ 300 dpi then opened the photos as layers, rescaled the layer, and moved it where I wanted. All went well until...

Most of the photos I have are lower resolution, so typically 2500x2000 pixels from a 16MP camera. However, I wanted to include a few shots from my daughters 24MP Nikon (she can afford a better camera!) that were 6000x4000 pixels. When I rescale those as layers, the layer vanishes. It appears on the layer list, but appears as a chequered box - as though the layer had been made transparent. And if I try to page up/down through the layers, nothing gets selected when that layer is active (although the legend at the bottom of the screen shows the photo/layer name correctly).

Is this a known bug? If so, at what size image does the problem start - as if I know where the size issue starts, I can rescale the images first before using them in GIMP.

  Another transparency question
Posted by: lruskauff - Jul 22, 2015 04:53 - Replies (6)

I really tried but I can't get this to work. I have been reading all of the post but they seems to match what I have done.l

I have an image and want to remove background. First I tried to use foreground selection but it would not select everything. So I used Color to alpha. My background was pink, now it is a checkerboard pink, so it looks like it worked. If I look at my channels dialog I have 4 channels (red, green, blue, alpha).

I do an export. I have tried both .PNG and .GIF. When I look at them on my desktop, I see a pink background. I also put one into my website just to see, but it also shows up with the pink background.

I am using version 2.8.8. If anyone has any tips I might have missed, thank you.

  PDFs and GIMP
Posted by: Knuckledra99er - Jul 18, 2015 18:48 - Replies (14)

Several months ago, I started thinking about similarities between GIMP image layers, and the pagination in .PDF documents.

Fiddling with several things, I believe i was even able to open some (parts of) PDF documents with GIMP.

Is there any way to use GIMP to assemble multi page PDF documents that will be readable with mainstream .PDF reader applications?

If there is a compatibility, what I'd like to do is combine several one page PDF files into one conventional multi-page PDF file, having the .PDF extension.

  Canvas size crash problem
Posted by: Sylveon Fetish - Jul 17, 2015 23:08 - Replies (12)

Gimp worked flawlessly on all 32-bit versions of Windows 7, now on a 64-bit OS, it is a different story. I get crashing while stroking selection or a path, and more frequently crashing every time I attempt to use the image-canvas-size menu. I can never get canvas size to work. At least the stroking path works 40% of the time, canvas size however never works. I tried to make an output of Gimp--verbose but the logging quits immediately after the main Gimp startup splash screen.

  Colorize the Image
Posted by: MAD King - Jul 17, 2015 22:43 - Replies (4)


I am trying to convert HSL to RGB, but every converter tell me that a minus (-) or negative number is not valid. Why does GIMP even allow to adjust the colors in the negative area if a conversion is not possible?

Thank you
