I have never used processing before and started learning it a bit to help a friend in their course as they have never done any coding before. One of the assignments was to make a simple paint tool that lets you change the color and brush size that you are using. To do this we made a sidebar at the bottom that had all of the color and brush size options which worked fine. I decided I wanted to try moving the brush sizes to a separate sidebar on the side so that there would be more room for more color options and more brush sizes.
The issue I have run into is now whenever I click one of the brush sizes both sidebars get completely filled in with whatever color I have selected. This completely covers all of the buttons in both sidebars so the user can't see the icons to change colors or brush sizes anymore. I cannot figure out what it is that is causing this issue and everything I have tried to change so far hasn't changed it. I'll attach the code and screen shots of program running to better illustrate what I am trying to describe as I am aware I may not have been super clear. Any ideas or help is super appreciated!Program on start up
Once you call stroke()/strokeWeight(), by default, the settings are applied globally. When you selected the thickest stroke, currently, everything else in the sketch will have the same stroke weight.
SAI or Easy Paint Tool SAI (ペイントツールSAI) is a lightweight raster graphics editor and painting software for Microsoft Windows developed and published by Systemax Software. Development of the software began on August 2, 2004, and the first alpha version was released on October 13, 2006. SAI's official release (1.0.0) was on February 25, 2008, and an update preview was released shortly after. It has been available on Microsoft Windows from XP to 11. It is available in Japanese, German, and English.
SAI is a lightweight painting application. The user interface allows multiple documents to be opened at the same time. The drawing canvas can be both zoomed and rotated using the sliders on the navigator or the hotkeys configured on the keyboard. The toolbar on the top part of the screen also includes a button to mirror the drawing view without mirroring the actual drawing. It is also possible to open multiple viewports to the same document. An application-wide scratchpad (which can be used as a color mixing panel) is provided, which is saved between sessions. Colors can be stored in the swatches panel.
Various raster drawing tools are implemented, such as the Airbrush, Watercolor, Pen, and Marker, which can all be easily customized, and stored in slots in the user interface of the application. There is also a set of vector drawing tools intended for inking, which, like the raster tools, can be configured to be pen pressure-sensitive.
Work can be done on separate layers, which can be grouped and have opacity masks. In addition to this, layers can be masked by clipping them to a lower layer. This allows one to add shading and highlights to an area without creating new masks for the additional layers.
Selection tools include the simple square selection, the lasso, and magic wand, which can be configured for anti-aliasing. There is also a selection brush tool, which can be customized like the drawing brush.
SAI comes with a full set of transformation tools that can work on selections, including move, resize, rotate, and a free (perspective) transform. Any series of transforms can be set up and then applied at once to a specific selection minimizing the softening of the image.
Some common features that exist in similar software, such as text layers, gradients, and shape tools, are not implemented, as SAI focuses on drawing and painting, while the final composition is often done using another application. SAI displays white and transparency in the same way, which may cause significant display differences when exporting to another program, such as Adobe Photoshop. There is also no printing functionality, but documents can be exported in a range of popular formats, such as .PSD or .BMP files, in addition to the native .SAI format.
Because the program does not focus on image editing, the only adjustments present are Brightness/Contrast and Hue/Saturation, and therefore no support of level editing, channel extraction, etc. Users may use another program for more complex editing, but when the image is brought back to SAI, its properties may be changed.
SAI also includes linework layers, which can be used instead of manually drawing linework. The linework layer include different tools designed specifically for creating lineart, such as the Line, Curve, Edit, Pressure, and Weight tool.
Various settings and features can be accessed and edited by the user either from the built-in Options dialog, or using the provided misc.ini file in the installation folder which allows additional options and customization. Existing brush presets can be edited, and the user has the choice of adding custom ones by placing bitmap files into the "elemap" folder. New canvas presets, as well as custom brush textures may be added by the user, in the form of grayscale bitmaps.
mtPaint is a lightweight equivalent of Microsoft Paint. It is lighter (requires only 1 MB to install because it depends on GTK which Ubuntu has out-of-the-box) than Pinta, which needs 20 MB disc space on a standard Ubuntu install because of the Mono dependency.
You just need an good introduction. At Meet the Gimp there are many, many comfortable video tutorials. It isn't easy to not get lost in the big number of options with gimp, but sooner or later you need more, than some simple program is offering, so it might be easier to learn one program in depth than first an easy one, and then the more complicated one too.
It captures screenshots, but it also has an edit mode for the screenshots (or some file you can load from your hard drive) with some basic drawing tools, which are well thought-out and quite usable for inserting arrows and numbers into images, cropping, etc. Things you do to images to cut +paste them into presentations, after editing.

Alright, first I wanted to say something, it seems that being busy lately isn't letting up all that much. So, if I don't post on any given Friday, then check back Monday, it SHOULD be up by then. I may also decide to switch to uploading the posts on either Saturday or Sunday, but regardless, more stuff! Now, today I wanted to go over the last of the stuff for what I've been going over lately, because they're all...connected, in a sense.
I again apologize for this late post. I have some things going on and I've been rather busy as of late. But, without further adue, here is the next post! Which should have been posted on Friday...anyway.
Today, I'll be going over four tools, because there all fairly simple and don't have much to any of them. So, I thought, why not? Though, this post is a bit longer then the others, so...read at your leisure. Anyway, first off, is the Move Tool.
Alright, I'm going to do two tools at once this time around, because there's nothing at all to the first tool. With that said, the first tool is the Lasso Selectoin tool. I also apologize for last week's late update, it seems the queu didn't upload the post at the time I had set it for.
Well, I know I said I wanted to get into painting and such a couple days ago...but I also said I wanted to go over a few more tools first, because I want to give a bit of a basic idea for using them first. That said, today's tool is the Selection tool....which works like it does in every program....
Well, I'm sure most of you, if not all, have already read this, written by my friend over at Photoshopfornoobs. Or was it written by a friend of hers? This is something that I, of course, very much agreed with her on, and I have been holding off on this until now. Why did I hold off? Because have my own way of doing things goddamnit! But in all seriousness, I want and will get into such things, I first wanted to go over, and still do want to go over some other tools and brushes.
These are, and of course were, just the basic brushes and tools for painting and drawing in SAI. I want you to have a basic understanding, if you didn't have any before, of SAI's main tools and brushes. That way, when I DO get into painting, drawing, technique etc. I can build upon that, and give some sort of idea of how to do a specific technique, as well as what brush you may want to use for it.
A very good blog post made by my friend over at Photoshop for Noobs about alternative programs for Photoshop, and of course these are all alternative programs for SAI as well, if you want to have more then one program at a time, since well, you know, while SAI is an amazing program, it can be beneficial to use more then one. (I use SAI for the most part, and Photoshop for anything that I can't seem to do in SAI or don't know how to do in SAI etc. Which is fairly easy, since you CAN save a picture in SAI as PSD (Photoshop file format) and this WILL keep all your layers and everything intact the same way it was in SAI. But enough about that....
