[Tutorial] PixaTool - Erosion & Dilation group


( For video tutorials Watch PixaTool playlist on youtube )

-

Erosion & Dilation sliders are very useful to make Dark/light pixels wider.

Using much pixelation makes the images unreadable if they are not made with big strokes.

To fix this, you have to use Erosion/Dilation depending if you want to show/hide light/dark pixels.


Mode
----------------------------------------

Two values
0 = Dilation (By Default makes dark pixels wider)
1 = Erosion (Makes light pixels wider)


Steps & Pixel XY
----------------------------------------

Calibrate how much width/height you want that colors and the position distance. Add for example 50 of intensity and play with their values and you will get perfectly how they work.


Intensity:
----------------------------------------

Just that, makes how much intensity apply to the values you provided above.


When is recomended to use it?
----------------------------------------

If your image is a floor, brick wall or similar and uses thick black/light lines or details use this group first to get exactly what you want.

Why? Because doing dark pixels wider will make your image darker, so next step will be adjust Brightness/Contrast/Light/Gamma/Exposure to fix this.


Example:

NOTE: At the moment this tool only can be purchased as part of my big game assets pack here:

https://kronbits.itch.io/1bit-game-assets

(This tool started as a small 1Bit image converter as addition to the pack but after the good results on any kind of palettes and styles has been updated constantly. Still some bugs to be fixed and features to be added. So, will be released here as a standalone app when all that stuff gets fixed, improved or all features added.)

Also is there a link to the palettes used in the dropdowns? That would be very handy.

They are used in the shader format. You can search on google lots of retro sites, wikis,etc.. have theyr palette in various formats ;) .

Hi :) I simply adore your PixaTool app. It's fantastic. I wonder, is there formal documentation anywhere besides the tutorials on YouTube and in here? Are there hot keys for the app besides those listed for H]ide, and F]ullcreen?

Many thanks for this awesomeness. <3

All the hotkeys are displayed in the interface.

Other things are that you can use mouse wheel up/down, arrows or av/re pag to move steps/values over a sliderbar but no much more.

I think there's a bug in C64 palette. It generates additional grey tone, just slightly lighter then the darkest grey.  And It desn;t seem to utilise the violet color at all.  Even when I import an image that is already in that palette all violet color is converted to blue.

Mmm, weird, i will took a look to that, thanks for the report.

I'm also having problems with exporting images. Both 132 nd 135 versions. 132 exports cropped image and 135 scales it down and displays on top left corner on the bitmap... I tried reinstalling and using different settings. Nothing helps.

Hi! Working on a update that should allow export any kind of size, even 4k. Hope to release soon! Also with a much better UI.

Great news!

Has the Mode for erosion & dilation been removed in 1.20? I'm using the win64 version:

Yes was removed, mainly because i always used the dark mode for get the lines/outlne and give space for Highlight/shadow sliders that i find them more useful and the Special FX tab.
