matherp said the display framebuffer is still only using 1 bit per pixel

It would seem the colours aren't part of the image so to save them may be quite difficult. Perhaps the saved B & W image could have the colours added in MMB4W with a program reading strings containing the Tile commands from the PicoVGA program.

Edit
The process could begin in the PicoMiteVGA program.
After each Tile command append the co-ordinates, pixel dimensions and FG & BG colours of that Tile set to a text file.
The MMB4W program can then use that to "colourize" each pixel of the BMP file by reading them and writing them back with the FG or BG colour.

Volhout said @Peter,

I guess this tile change does not make it easier now to get a SAVE IMAGE with color ...??

Volhout

Edit: tested most of my programs, all work
Only the hi-res chess program needed fixes.

BTW; Is there a way to read the Tile values from a Screenlocation?
Since the BMP file format is not that complicated, maybe a short Basic Sub can write a 24 BIT BMP File account the Pixel and TILE values

Is there a way to free up enough memory after running the Logic Analyser program to save an image of it. At the moment Save Image only produces a very short corrupted file.

Are you trying to save to the flash drive? In which case the file is too big . Save to an SDcard and it should work.

Hi Peter,
Many thanks for fixing the triangle bug. All looks good now!
With best regards, Paul.

Nothing so constant as change.

This one is better.
Not only does it now save the images in 4 bits/pixel so much smaller files
but you can also blit the colour if the blit aligns with the tiles

@peter:
i don't think so. See images attached, the first image is the version for PicoMiteVGAV5.07.07b25 (specifically for vollhout) and the second image is the latest PicoMiteVGAV5.07.07b25 (version2).

It was a "Seniors Moment"

Successfully saved an image to SD card before running LA21, but after exiting LA21 with Ctrl-C it produced the small corupted file. Forgot I had switched to A: to run the program from there.

Beta 25 is excellent, thanks Peter.

When re-displaying saved images in Mode 1 on the PMVGA they can be colourised like this example for the Logic Analyzer.

' LA_21_b24.bas mode 1 "load image" colouriser

MODE 1:Colour RGB(WHITE),0:CLS :Font 1

TILE height 16

For ch% = 0 To 6
TILE 14,5+ch%*3,RGB(yellow),0,66,2
TILE 0,4+ch%*3,RGB(midgreen),0,80,1
Next

Then load your image

> Load image "LA_01.bmp"

Hi Peter,
Like you I almost always only use USB to connect and edit using a terminal screen.
If I use options like this

PicoMiteVGA MMBasic Version 5.07.07b25
OPTION COLOURCODE ON
OPTION KEYBOARD US
OPTION DISPLAY 60, 106
OPTION DEFAULT FONT 7, 1

or even

OPTION DEFAULT FONT 8, 1

to give me more lines and columns while editing using a terminal, in the terminal it works great in colour.
If I look at the VGA screen some of the top lines of code on the screen are blank, they initially appear while 'pg up' or 'pg down', but immediately disappear, there are also blanked lines further down the screen as well, but the top is the most obvious, all lines below about half screen always seem to be complete.
I realise that using Font 7 or 8 will not give me colour editing on the VGA screen.
I have tried this at all cpu speeds.

Is this something I can no longer do, because of the new colour tiling?
Any help appreciated.
Regards, Kevin.

Should work - another bug to fix. Is it OK with OPTION COLOURCODE OFF?

Hi Peter,
If I try,
OPTION COLOURCODE OFF
The VGA screen is then normal, all lines visible with font 7 & 8.
