Well thats good to know! Thanks for all your, and CAE_Jones, feedback. I hope everyone enjoys and finds BrushTone useful! Heh.

If there are any further issues, feel free to let me know.

Thanks Magurp for your hint! Now I want to try your program with real photos and real images, also complex, like nature and persons. I will tell you! I've tried for now with a photo, but the program views me only some line, but I can't understand that is a photo of a person. But I don't know if is a problem of the photo. I will try with Others.

Hmm. By default BrushTone automatically creates a 64 by 64 black canvas on start up. If your not hearing anything other than a click with the sonifier or the same low pitch with the window scan, then that would imply that the canvas is entirely black, for whatever reason. Try loading some of the sample images like "dithering.png" and enable Batch Mode and Loop Mode, if its loading any of the images properly that should give some results. Whenever a new image is loaded, it will replace and push the previous image back on the stack, and you can switch between them by pressing "tab", but it will not replace or delete images in the process. So if you load an image on start up, the default black canvas will be pushed back on the stack and the new loaded image will be displayed.

For color, you can press any of the number keys from 0 to 9 on the keyboard, but to customize them you have to press and hold a number key. You can then press the up and down arrow keys to select a color by name, press the right arrow key to customize its RGB values, or press the left arrow key to pick a color from the canvas to replace the currently selected color.

You say you selected the canvas and filled it with Black, are you using the Select Tool or Select Canvas function to replace the color of the canvas? Can you describe what steps you take to fill the canvas with black?

Bleh. I've found a few bugs involving the Select Tool and Select Canvas functions, so thanks for digging them up, heh. It seems if you pick the Select Tool, hit space, then use the Select Canvas function, it won't deselect properly. Another issue seems to be if you select a region, then change the tool it will glitch out until you pick the select tool again and hit space. I'm putting together a fix now and i'll upload it in a bit.

The Select Canvas function will automatically select the whole canvas, which will replace the canvas with the currently selected color, but it will also hold on to the previous region for you to move around. Selected regions aren't bound by the canvases borders, which is why it went so far, the number keys for selecting colors will also not work, and the Sonifier will only scan that selected region until deselected. Instead of the normal 3 tones that play per pixel, it will only play one standard tone when a region is selected. Bugs aside, you can deselect a region by pressing space, using the "cut" option in the edit menu, or pressing backspace to delete it. You  can tell if you have a selected region by holding "C", normally it should say "Canvas X by Y", if it says "Region X by Y" then you currently have a selected region.

Edit: just finished uploading the update, let me know if theres any further issues.

Hm, that seems like a pretty good representation of an Inca Cross, good job!

In traditional paint programs, erasing things is more just painting over them with a default color. In MS Paints case, its the color white. So technically you can "erase" things by painting over them with the color Black, which is BrushTones default. You can also wipe a region of a canvas by using the select tool to grab a region and replace it with black on the canvas, then delete the selected region by pressing backspace.

The circle tool admittedly doesn't work too well when working with sizes of around 1 or 2 pixels. When you first press space it places an anchor, it then draws a circle outward from that anchor point, the distance between the anchor and the cursor being the radius. So, if you move the cursor 3 spaces from the anchor point, you would be drawing a circle 6 pixels in length. Also the circle tool won't draw anything if your only going along one axis. The Line tool should work along both X and Y axis' simultaneously though. Also not sure why the save system wouldn't be speaking the names of the keys being pressed either, does it say anything when you press backspace to delete typed letters?

Hm, this would be the second time the TTS outputs been flaking out. I'm not really sure whats up with that, it might be system specific since it seems to effect people sporatically, at least from the reports i've gotten so far and my own tests.

Unfortunately no, there is no implemented way of increasing the pitch range. The pitch currently covers a range between 0.5 to 1.5 to represent numerical values from 0 to 255, if I tried pushing it any higher it would distort the audio and cause artifacts, if its much lower it would be difficult to hear it at all. It could be possible to narrow the range, such as having it only view color values from 0 to 125, or 85 to 170, but that would prevent users from percieving colors outside those ranges. Design wise the current system isn't necessarily a bad thing, if there are very small differences in colors that make it hard to tell the difference between tones via sound, there's a very good chance that sighted users would have a hard time telling the difference visually too. Well, unless their tetrachromats.

You can press and hold the "Z" key though and it should speak the raw numerical RGB values of the color under the cursor, which you can use to compare with adjacent colors for greater accuracy.

So, I was drawgin this thingie...And discovered that there wasn't enough Space at the bottom to finish the stuff, so I decided to try to cut and paste it a bit higher on the canvas...I can't seem to figure out how to do this though...
I placed an anchor at 0,0, then went to something like 50,63 and selected that. Then I went to the edit menu and pressed enter on cut, so far so good, stuff was replaced by selected colour and all...
I then went to 0,5 and entered the edit menu Again, hitting enter on paste, and it now moves around on a selected region with the selected colour...Not sure if it's supposed to do that...I've also tried pasting after making an anchor point, still no luck...
What am I doing wrong? Lol.

@AlexN94
Chances are it would end up pixellated if you scaled it up, but that depends on the style. Pixel Art usually work anywhere from 8 by 8 to full screen in sizes, and depending on your approach jaggedness could be part of the appeal, heh. You could also draw a whole image using smaller 64x64 "tiles" then paste them together to form a larger image, as the case may be. Having said all that you can increase the size of the canvas by using the "Resize" function in the Canvas menu, and if you want to scale an image up or down use the "Stretch" function in the Image menu.

When pasting images it loads the Copy Buffer into an Active Buffer, in this state you use the arrow keys to move around the pasted image, which is the same as selecting a region, the pixel tones will be replaced with a single generic tone, and you will not be able to select new colors. Technically your "holding on" to the selected region to position it on the canvas, to paint the selected region on to the canvas you press Space Bar.

Hm, i've also seen a few other programs use a typed input feature for drawing shapes, but I wasn't entirely convinced at how useful it would be compared to a more "hands on" approach. There don't appear to be any conflicts in key input to prevent putting in such a feature for tools though, so i'll see what I can do.

@Mayana
The way the TTS voice is setup it scan's the list of available voices, and if more than one is available it picks the second one, whichever one that may be. It seems that this is less than ideal, i'll work on adding a menu system to allow users more control for configuring the TTS functions.

The position of the anchor and cursor are saved in copied images, so however you selectedthe image, thats how it will paste. So for example if you select an image from the lower right to the upper left, when pasted the anchor will be in the lower right relative to the cursors position.

Nice! Kind of reminds me of those Japanese lucky cat statues, heh.

I've just uploaded version 1.2.1 which includes a few little fixes and cleaned up the TTS a bit and added a new select function. Pressing F7 will cycle through all available TTS voices, so hopefully that helps fix the language issue.

I've been thinking about your suggestion AlexN94 for direct coordinate input using tools. I think what I may do is make it so when selecting a tool you can enter an X and Y coordinate like you can with the Resize Tool. The current position of the cursor would then act as the anchor allowing a way to create shapes without having to pan the cursor so much. What are your thoughts on that?

I'm familiar with the Swamp Map Editor, CAE_Jones was kind enough to share a copy with me, heh. I think he may have mentioned being able to place anchor points and such in relation to the select tool. Earlier in development I played around with the idea, but ran into conflicts when implementing the other tools so kind of side stepped it. From what I can tell the Swamp Editor allows you to place one marker to snap back to at any time, looking at it now I think I can implement that with something like Shift+R to set it, and R to snap back.

I'll try implementing the coordinate changes to the Tool menu and put some more polish on the TTS menu, I can also add a Shift+Tab to move back on the canvas stack as there can be a lot of images loaded, and apply a way to change the rate of speech. Unfortunately there is no pitch control with the current API i'm using.
