Red ochre

I may have misunderstood but If you want to give the impression of rotating around the vertical axis, through the picture plane, then the "Quadrilateral reshape" plug in is very useful.

I have problems with this too. I try to save before using it, as it can crash if the tolerance level is too broad. It probably doesn't actually crash, but life is too short to wait. It would be helpful to have some way of aborting it, once started, too avoid a near infinite hang, allowing you to reset the tolerance to something it can deal with.(2gb dualcore Vista)

Thanks for the reply. Sorry, I still don't understand. I'm reading from the src into an array, then changing the values in the array (to avoid unwanted 'feedback'from refencing pixels that will be changed), then using these new values to write to the dst. At some stage in that process the plugin is deciding that a single 'line' pixel which is surrounded by 'background' pixels - isn't? (when I can see it is !). Surely if it wasn't writing to dst along the ROI borders, the image would have either solid horizontal lines or lines of the unaltered src image(colour)? The process does what it should inbetween these borders and on the borders still manages to 'write' the part-processed image - ie black and white. It just isn't changing it to what it should be from the array. Black or white (from true, true or false, false in the array) & red if added (false, true), cyan if removed (true, false). Anyway - thanks for the reply - If you can think of anyway round this or any plugins (with published code), which have overcome this problem, I'd be very grateful.

I'm working on the attached plugin (which creates various types of ink outline). The problem I can't solve, is in the 'enhancements' section, where I am trying to remove isolated pixels and add in pixels to fill gaps. I'm doing this by 'looking' at the surrounding pixels - However, I think the rectangle of interest is stopping it seeing around the current pixel when it borders 2 ROIs. I am testing the plugin by marking line pixels that have been added in, red, and those removed, cyan. If you zoom right in on the attached image you will see where it's going wrong. I have tried the 'g.clip' code with no effect and really think I need someway of making it consider the whole whole image as 1 ROI to avoid this. Of course it could be due to something else. I would be grateful for any ideas on how to solve this. Please bear in mind that I'm very new to C# and this is very much a 'beta' version - it will need a lot of tidying up, but I need to sort this problem first. Many thanks By the way I think the answer to the question is using a method outside of the render loop - but haven't got back to this yet. /* =================================================== */ /* */ /* Advanced Beta Ink drawing.cs */ /* (c) 2011 Red Ochre (John Robbins) */ /* */ /* Description: produces various ink outlines */ /* */ /* ========================================== ======== */ // Name: Beta Complex ink drawing // Author: Red ochre (John Robbins) // Submenu: Advanced // URL: http://www.getpaint.net/redirect/plugins.html // Title: Complex ink drawing - 2011 Red Ochre #region UICode byte Amount1 = 0;

I also had an error involving SetUpFrontend.exe when installing 3.5.7. I'm attaching the screenshot of the warning - but paint.net seems to still be working o.k.? Sorry this doesn't help you - but it may help those trying to fix it? Edit: - I removed the screenshot to save upload space - It's irrelevant now were v3.5.10 too!

Hello again, I've reworked the effects formerly known as "Earths", which is now "Earths and greys", and "psychocolour"is also attached. Hopefully the code is a lot more readable now ? I haven't started on "contour" yet - as I want to fully rewrite it. Is this the best forum to 'publish' them, or should I have started a new thread?

I'm working on the next version now, but probably won't post it tonight. Thanks for reviewing the last one - all useful points. The next one should be tidier.

Actually the color wheel seems to be behaving ok now

Thanks for all that work - it is clearer. One thing though - that's actually the code for 'Phsycocolour2' -my fault for uploading them in the wrong order and not adding the the title at the top. I intend to add more strange effects to this one, as I can just add a new 'case, break' for each block. The dlls are correctly named but I will rewrite the code to make it tidier and more readable, and possibly organise UI more logically too. One question - the colour wheel always seems to default to the primary colour setting despite giving it a value in the UI code. Is that just the way it is or can it be made to take the initial value I've assigned ? Thanks again for the work - I've got loads to learn/discover - I tend to litter the code with casts when I'm 'debugging', then find the fault is somewhere else and forget to go back and write things as simply as possible - lazy habits already!

Thanks - I will improve the readability next time, before I send them - they've sort of evolved rather than being logically designed, bits added as I've found out what things do. Thanks for corecting the / code mistake, sorry again - will try out the Int32Util.. option. I will be back tommorow - I've got plenty of questions - if you have the patience

Whoops - sorry didn't add the "[/code]" at the end.

Thought it time to show you how messy my code is - but it seems to run ok for me and it's the first stuff I've written since the Commodore 64. dlls zipped and attached hopefully. #region UICode byte Amount1 = 1;

Thanks for the reply. - I just wanted to play with generating lines without refence to the src at this stage. Later I would like to pick out say dark pixels( B+G+R<= Amount1) then use this to create the co-ordinates for the g.Drawline command. - Very ambitious, but what's to loose. Do you know if this(the cs0012 thing) is known issue with Codelab, or is it just me? I will post some (ametuerish) beta plugins shortly, just got to reread the rules and zip them up. Thanks again

As a new member, firstly, thank you for Paint.net and Codelab. I have no C# experience but have still managed to write some plugins that I am very pleased with. The problem I have is with the default code for copying the source to the destination without using the loops. When I use the 'new' option and select the option to include this, it adds the code, but the errors window shows two cs0012 errors. This also happens if I write the code manually copying from tutorial4. (dst.CopySurface(src,rect.Location,rect;). The error says: "System.Windows.Int32Rect must add reference to WindowsBase,Version=3.0.0.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35 (cs0012)" and the same reference with "System.Windows.Point". I have tried copying and pasting the code into visual express, but I really am a novice and can't see a way of adding the relevant reference. I really do not yet understand visual express. Is this a known issue, or is it my set up? Can it be resolved or do I just have to use the loops to copy everything over before rendering anything new? Presumably there should be some sort of 'using' statement in the 'hidden' code which points to the relevant library, but since I don't know where this is or the correct syntax to add it - I'm stuck. Any advice will be appreciated.
