Thank you for creating this handy tool! <3 Really makes it easy to apply different palettes to my GameBoy Camera pictures :)

What do the arrow buttons do? There are left/right buttons below the "Image" label and up/down buttons below the "Palette" label. They seemed to do nothing when I clicked them.

And I'll just leave a few feature ideas here, although some of them are maybe only useful for my specific use case ;)

• being able to change the palette order would be nice. I imported a whole bunch of palettes and would have liked to rearrange them afterwards in order to put similar palettes next to each other.
• I would have liked to set names for my palette mappings. The default name could be the palette's filename (without extension)
• It would be great if instead of saving one big output picture, I had the option to save individual pictures for every palette in my project. The output filename could be "original-filename_palette-name.png".
• if relative paths in the project file were used it would be more portable. (I have saved the project file in the same folder as my images).
• on the right side all the images are in one vertical column. I imported 14 palettes and have to scroll up and down a lot. But there is a lot of unused space available that could be used to show all the images in multiple vertical columns

Kind regards! :)

Hi!  thanks for your kind words!!  So glad you are finding the tool useful.

I'll try to answer your questions and concerns as best I can.

> What do the arrow buttons do? There are left/right buttons below the "Image" label and up/down buttons below the "Palette" label.

These buttons are for scrolling through the available colors if the palette contains more colors than can fit on the screen at once.

I hadn't thought of it, but I guess it is funny that the 'Image' palette gets a left/right arrows and the 'Map' palette gets up/down arrows.  :)

> being able to change the palette order would be nice. I imported a whole bunch of palettes and would have liked to rearrange them afterwards in order to put similar palettes next to each other.

Colors within a palette can be re-arranged at any time by simply dragging the color squares around.

However, I think maybe we have our terminology a bit mixed up here.  So if it's ok, I'd like to define a few terms here to make sure we are talking about the same thing.

* The 'Image' palette is the list of colors in the source image.

* The 'Palette' or 'map' palette is the list of colors to use in the destination image.

* A 'Map' is a mapping from colors in the 'Image' palette to colors in the 'map' Palette.  

If I am guessing correctly, when you say 'palette' above, you mean what I have dubbed a 'map', is this correct?

If so, I think I see what you mean.   Currently, you can add, remove and clone 'maps' but you cannot re-order them.  Actually, I have often wanted this feature myself and for the reason you suggest, I create a bunch of maps and then want to re-arrange them a bit to put like ones near each other in the list.

I'll think about how to add a way to re-arrange the maps without adding too much clutter to the UI.  I'm sure it can be done.

> I would have liked to set names for my palette mappings.

I hadn't thought of this before, but that's also a really good idea.  Again, I'll think up a way to add this without complicating the UI too much.

> It would be great if instead of saving one big output picture, I had the option to save individual pictures for every palette in my project.

Another great idea.  I had only just recently added the ability to select between stacking the maps vertically or horizontally in the output picture.  I'll work on adding a third mode for saving them a series of separate images.

> if relative paths in the project file were used it would be more portable.

Hmm...  Sometimes I work out of a C: drive and sometimes out of a D: drive, so this is an issue I have encountered myself as well.   On the other hand, I can think of cases where absolute paths would be preferable.  For example, if the source image is in some arbitrary path not really related to where you palette or project files are located.  Still, let me think about this.   What you'd want would be paths that are relative to the project file, right?  

FYI, as a workaround until I get something working for this, the project files are all just plain text, so if you ever move things around, you can open the project file in any text editor and change the image and palette image paths manually.

> on the right side all the images are in one vertical column. I imported 14 palettes and have to scroll up and down a lot. But there is a lot of unused space available that could be used to show all the images in multiple vertical columns.

hmm.  I see what you mean.  Although, this does depend on the aspect ratio of the source image and the current zoom level.   For example, if the source image were very wide or you were zoomed in very closely, then you might not have as much free space.  Anyway,  I'll think about how to fit more maps into the preview area.

If it helps, you can switch to any map simply by clicking directly on it in the preview area.  This can help save some time vs. just using the map up/down buttons.

Thanks again for your nice words and your thoughtful, well written feedback.  I can't promise when I'll get to making any changes but you've actually caught me right at a lull between projects so hopefully I won't have to keep you waiting too long!  :)

ah, thanks for the arrow button explanation. I only worked with 4 colors so far ;)

about the reordering idea, I really explained it a bit confusing. But I think you got it exactly right. Changing the map order would also change the order of appearance of the preview pictures on the right that have the maps applied. This is really what this is about. It would allow me compare output images with similar mappings / map palettes applied more easily. (One implementation idea would be via drag 'n drop, by dragging and dropping the output images.)

That's great! :) Since your tool also supports CLI mode, I already created a little PowerShell Script that creates separate images, but having this in the UI would be more comfortable :)

> What you'd want would be paths that are relative to the project file, right?

Exactly. Maybe the user could decide if he wants relative or absolute paths. Ideally the save dialogue would have a little checkbox for this. But I don't know if that's easily possible to add. This was just a minor idea though, since editing the text file is always possible, as you said ;)

About fitting more maps in the preview area: you're right, it depends very much on zoom and the source image dimensions if this is useful. But I don't think any smart logic would be necessary to determine a layout of the preview images. I'd be happy if I was able to edit the amount of vertical preview columns manually and this would keep things simple I think :)

Thanks for considering my feedback! I'll be eager to test any updates you release :)

I am very glad to hear your news, about the error, I was a long time trying to replicate it without success, but from experience with the application, I guess it is related to this other problem, as you can see, sometimes the cursor does not transition correctly with the Windows cursor, not allowing to interact with the window, I hope you find this information useful, good luck! 😉
