Win 7 - 64bit, Gimp 2.6.11 and I downloaded color_source.png from this thread. I had the color_source.png as my top layer, and a solid white layer (no alpha channel) and ran the filter on the white base layer. The layer has a slight bit of the color from the top layer, but barely anything. Any suggestions as to what I am doing wrong with it??

If you use a white background for layer, you need to toggle the white layer mask option, otherwise use a transparent layer instead.

Got to be a transparent layer Gregg. If you have little color and then rest white, the white will color in most of the image. White is a ligit color by the way fyi. Keeping the top layer transparent also makes sense since you got to be able to see what you are doing.

With only 512 mb of ram this plug-in isn't for me. :lol

Still waiting for a 640x400 gradient to color itself. (started 35 minutes ago)
It has just now reached the halfway mark.
Probably why it crashed in the first place on my 2600x2600 image.

By the way when i desaturated the image it automatically removed the alpha channel
so that wasn't the problem i do not think.
Pretty sure now that it was my sloooow machine.

Oh well.

My top layer is transparent with some painted areas, and my bottom layer has no alpha channel. My bottom layer was white. I tried it with an actual photo as my bottom layer and my transparent top layer. I'm getting some results, so I will keep playing with it. It is a sweet plugin with immense potential once I get it.

It works real fast as long as the colors are blocks.On gradients it needs to render more colors so it's much slower.With 1gig ram or better it should render pretty quickly either way.
PhotoMaster here is what i did.
I created a new white bg doc at 640 pixels wide and 400 pixels tall.
Then i created 3 equal horizontal rectangles like a French flag on the new doc layer.
After that i added a new transparent layer on top and gave it 3 different colored paint strokes.
I chose the bg layer and ran the plug-in
I chose the colored layer and clicked okay - 3 minutes later i had a French flag colored pink, green, and powder blue on the bottom bg layer.
It seemed though that all my paint lines were brighter than the rest of the colors that were rendered in.
I could see the lines in the colored stripes as a lighter color.Could be just my machine but i don't know.

My advice is to not run this plug-in on a machine with less than 1 gig ram.

In my case a selection and then a gradient map or colorize would be faster. :lol

Because it was divide into several part to process(only when image size bigger than 1400x1050)

Does the Windows binary allow you to work on multiple images in one GIMP session? It won't allow you to do so in Ubuntu. I have to close GIMP and restart if I want to work on a separate image and this totally sucks.

if you compile yourself, you can add this line
colorizevals.marked_id = default_drawable->drawable_id;
to the file "colorize-plugin.c" as the following code show

Code: Select all

static gboolean colorize_dialog(GimpDrawable *default_drawable)
{
   GtkWidget *dialog, *combo;
   GimpDrawable *marked;
   gint status;

   gimp_ui_init("colorize", TRUE);

   dialog = gimp_dialog_new(
      "Colorize", "colorize",
      NULL, 0,
      gimp_standard_help_func, "plug-in-colorize",
      GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL,
      GTK_STOCK_OK, GTK_RESPONSE_OK,
      NULL
   );

   gtk_container_set_border_width(GTK_CONTAINER(GTK_DIALOG(dialog)), 12);
   gtk_box_set_spacing(GTK_BOX(GTK_DIALOG(dialog)->vbox), 6);
   // add this line set marked_id to default to avoid get invalid id error
   colorizevals.marked_id = default_drawable->drawable_id;
   if (colorizevals.marked_id == -1)
      colorizevals.marked_id = default_drawable->drawable_id;
   marked = gimp_drawable_get(colorizevals.marked_id);
   if (!marked) return FALSE;

I had to come back and re-read this post to see what I wasn't getting in regards to my errors, and I quickly realized that although I did have this:

Code: Select all

if (colorizevals.marked_id == -1)
      colorizevals.marked_id = default_drawable->drawable_id;
   marked = gimp_drawable_get(colorizevals.marked_id);
   if (!marked) return FALSE;

I didn't have this:

Code: Select all

// add this line set marked_id to default to avoid get invalid id error
   colorizevals.marked_id = default_drawable->drawable_id;

So, I added those two lines above to my c file and recompiled and woohoo, it works. Thanks, JamesH!

You are welcome
Better way was use gimp_drawable_is_valid to check the drawable is valid or not

Code: Select all

// add this line set marked_id to default to avoid get invalid id error
if( !gimp_drawable_is_valid(colorizevals.marked_id) ) colorizevals.marked_id = -1;

I can't see this plugin doing anything.
I am using gimp-2.8.0 on Windows.

I took the sample image from here and made it black and white with an RGB mode.
my opera com/area42/blog/gimp-colorize
I then added a transparent layer.
I then added the stripes to that layer.

When I do Color-Colorization it auto-selects the layer as there is only one choice.
I don't make any changes to the options and it runs.

But the output is still the same as if I had done nothing at all.
I still see black and white with my coloured stripes on it.

I tried compiling the source on Linux using the code from these 2 repos:
github com/weibel/colorize-gimp
bitbucket org/grimboy/colorize-gimp/changesets

But I still had the same effect i.e. no colour change.
Am I missing a trick here?
I have attached the xcf file for others to try and explain what is going on.

By the way, is the code for any changes and build/makefiles etc in a public repo?

I ran colorfy on the background layer and ended up with the black and white with the colored stripes. I ran it again on the transparent layer and got an all black and white pc with white and black lines as seen below.
