When I open the Levels Adjustment window, and I click on "Auto," it autolevels the image fine, but the central slider on the Output bar is not updated with the value that the autolevel sets. All of the other sliders are updated and display at the right amount.

Much of the code for differnet features is similar. For instance, aspects of the code for each of the tools are identical. The number of lines of unique code is much less than 105000. If you have programming experience, you can work your way through the PDN source code in less than a day and understand most of it. Just looking over the source for the tools and for the example effects is good enough (or at least was for me) to get started with writing code for effects. CodeLab helps by simplifying the amount of code to be written (and, of course, by compiling while you code so that changes to code may be seen immediately).

Perhaps you were on the wrong layer? Try cropping while you have the other layer selected. Or...try pressing Ctrl+I before cropping. This inverts the selection. Maybe what you had selected was the opposite of what you wanted to have selected.

What are the units for the X and Y Pan boxes in the Rotate/Zoom tool? I'm looking for an easy way to linearly translate objects a specified amount (without using the mouse and without pushing the keyboard arrow keys several hundred times). I've noticed that if I hold Ctrl while using the arrow keys, it moves in increments of 10 pixels. Perhaps a control to change this increment could be introduced. If/when a more adjustable grid is implemented, perhaps the grid width could control the Ctrl+Arrow Key movement amount.

Lol aatwo; nice stuff! Your images remind me of http://www.ultimateshowdown.org You should make flash animations! (and webcomics...lol) (I know people keep telling you that...)

Try copying what you want a second time. Paste will not be deactivated if you have an image on the clipboard. Copy will not be deactivated if you have something selected. Just try doing it a second time...it should work.

Ah you're right! The red was drawn after the zoom error thingy was done.

The starting and ending colors of the gradient. Like if you want a gradient that goes from black to green, you would make one pixel black and one green (the starting and ending colors). Then, you would select the two pixels (and only the two pixels). Then, you would resize the selected pixels, and when you do so, Paint.Net will automatically blend the two colors for you.

Each individual aspect of this method is documented (how to use each tool). However, you are right that the entire process, as a whole, is not explained in the help pages. I have answered the same exact question you had several times on this forum...perhaps it is time to include something in the help file. I will write a tutorial to put on the Tutorial forum page.

It is an intuitive method to cancel what you are currently doing. Even if it weren't, the problem should be fixed anyway. Image working on something, and you accidentally press Ctrl-Z before picking up the mouse button...you could lose the work you were working on.

It crashes for me too. While the mousebutton is down with the eraser selected, when you press Ctrl-Z it crashes. All other tools behave fine. Interesting catch Paranor!

Also, when I press the "Delete" key instead of "Backspace" to delete code, the code is not recompiled after .5 sec.

Logancale seems to want the background to be transparent. What you do, is you click on the "Background" layer in the layers window. Then, select all of it and press Delete. This makes it transparent. Now, put your text in. Then, when you go to save the file, make sure you save as either a .gif or .png so that it will be transparent on all pages.

At the bottom right of the window, there is a little window that says "Layers". Click the button at the bottom that shows a page with a plus sign (+) on it. This makes a new layer.

The trick is the "Move Selection" tool. First, simply select the entire image by pressing "Ctrl-A". Then, click on the "Move Selection" button (it is next to the lasso). Now, hold Shift on your keyboard. Drag the corners of the selection box to change its size. Holding Shift keeps the aspect ratio the same as what you started with. Position the selection window around what you want to make the final image. Press Ctrl-Shift-X to crop the image to the selected area. I think that is all...let me know if there is anything else you need (or if you are confused about something).

I have several bugs/suggestions: When a file is opened, it would be nice if the "Name: " text box were updated with the file name (minus the .cs). It does the opposite while saving, so I thought it would make sense to do this while loading. Also, the ability to scroll sideways instead of wrapping text would be nice. Or, as in my copy of Visual Studio, have a small indication to the side of the text box that indicates that a line has been wrapped (I understand this is harder to implement). I beleive this is more of a suggestion for Paint.Net and not CodeLab, but it would be nice if the image could be zoomed/panned while changing things in an open Effect dialog (or CodeLab). When an error shows up in the error field, and I click on it, the text in the text box that is causing the error is highlighted. This is great, however, if the erroneous code is not currently visible, nothing happens. It would be nice if the code edit window were automatically scrolled to where the highlighted error can be seen...otherwise, it is hard to find the error. One final thing: The code line enumeration starts at line 13, and sometimes error messages refer to things on lines such as "10." For example, if I change something in the first line like if I change "Render" to "Rendxer" (for no reason, obviously), it reports an error on "line 10". I understand that this happens becuase there is actually more code above what can be seen. I don't think it can hurt to show this code. Overall, however, I'm extremely pleased with CodeLab...it is a great tool!

Ok...I have the colors working. Thanks again for the help! What about Tolerance? I'm looking at EffectEnvironmentParameters.cs and it seems that only the colors, brush size, and selection are available.

Good point...didn't even think to use Visual Studio while looking through the source for reference. I have been using CodeLab for effects coding...it's great how fast changes can be seen! Thanks for your help!

EffectEnvironmentParameters? Please explain the use, or let me know which file might show an example use.

Is there any way to use the user-selected foreground and background colors from within an effect? I have tried "Workspace.Environment.ForeColor" as it is used in various tool source code files, but the effects system (and/or CodeLab) won't let me access "Workspace" from within the effect code. Is the only solution to allow users to input colors through controls in my effect? -John

Nice approach Pickle...I have been doing it the hard way (blurring the edges of the image)...

To where should bug reports and the like for the CodeLab utility itself be directed?

Pretty cool effect...it works well! Some neat results may be obtained! Thanks!

Yes just like I said earlier this morning in your other post:

You can do this in Paint.Net! (or at least I hope I understand your request...) First, simply select an area of the size you want. Then click on the "Move Selection" button which is next to the "Lasso Select" button. Then, you can slide the selection around on the image. (like, as you say, pointing the camera differently) If you want to change the size of the selection, hold Shift on the keyboard and then drag the corners of the selection box around. (like, as you would say, zooming the camera differently) When you are satisfied with its placement, you can press "Ctrl-Shift-X" to crop out everything except the selection. If this isn't it, try rephrasing...I love to help!
