To publicate in an article, I need to enhance a Figure DPI to, at least, 1200 DPI.
I have an image that I got from another article and wanted to use in mine to substantiate the text, but, in the original article, the image is smaller than the size I need to use. When I try to resize it, the quality gets worse and the DPI is way below 1200.
I saw posts saying that using GIMP I could solve this problem by going to the Image Scale tool and changing the X and Y resolutions. After doing it and changing to 1500, I tried to export the image as pdf (what turned to png in the end), but, looking in the properties, it showed 504x370 instead.
I just bought wacoom bamboo. I installed drivers and tablet is seen and works fine with system and included with drivers sketchpad (including pen sensitivity). I can draw with it in gimp, but i can't use brush dynamics because gimp doesn't recognizes my tablet. In Input Devices I see only Core Pointer. I don't know what to do.
I tried to clone 50% opaque layer on another layer. The result is the same as cloning 100% opaque layer. How do I clone translucent and semi-transparent image?
My OS is ubuntu 16.04. I use "unity tweak tool" for workspace settings. When I use "super + s" keyboard combination for alternating workspaces, gimp works fine.
However When I use mouse click for alternating workspaces, gimp won't receive any painting inputs. That means I can't paint on the canvas at all.
I just recently updated from a previous version of gimp to 2.10 and have about 16 minutes ago found that the Brightness and contrast options show a accurate preview of what "should" happen but instead it does nothing.
I also just tried to use "levels" to try and accomplish the same effect but that also did the same thing (nothing)
This is a new image that has RGB color ect, but ill add more information here if i need to clarify things.
I have just solved my probleme of saving file (see thread file-png-save-defaults) by replacing one part of the code for another that I found on internet.
I would like to understand why the one I use at fist didn't work.
That is a problem of string building. Below in the code, two different way to build a string (which is eventually insert in the save file-png-save-defaults function).
The option number one is working. The option number 2 is not. Do you have any idea why ?
And the crual thing is that the function strcmp, which compare string, display 0, meaning that it is the same string.
Why then one of them isi working, but the other one is not ?
I've been trying to add a shadow to the attached image - I want the shadow in front of the image with a light source being behind the subject to the left.
I just can't figure it out. I've tried Drop Shadow & perspective shadow but can't find any way to add it to the front. I've also tried Gmic and Layers Effect.
I'd really appreciate any advice as it's slowly driving me mad this morning!
