Graphicscreen editor to show which colors are active in current charblock

[mokdevel]

• Import a multicolor bitmap picture (eg. koala)
• Each char consists of three colors and background
• When clicking on the char block, the colors should be shown on the right side of the image (Background, Multicolor 1&2 and Custom Color). Currently the stay as black.

Tested in WIP (7.3.5)

Second issue which may be related to the above.... The character bitmap (4x8 in MC) is shown under the colors. I can draw in it with mouse. The color selector under it does not have any logic. Pressing a color selects weird colors:

• Select $1 (white) -> $b is painted on screen
• Select $2 (red) -> $6 is painted on screen
• Select $7 (yellow) -> $f is painted on screen

Regarding the second issue - it seems to be for the imported image. If I create another graphicscreen and do full copy/paste, the color picker works as expected.

Hmm.. there is something with the import. Once I've imported the image (png of a MC c64 image), I do a full copy/paste to another graphicscreen. The image looks as it should be, colors are correct and the c64 color limits are considered. But something is broken with the colors when doing !media.

!media "gfx_ptower_big.graphicscreen",bitmapscreencolor
OR
!media "gfx_ptower_big.graphicscreen",color
!media "gfx_ptower_big.graphicscreen",screen
!media "gfx_ptower_big.graphicscreen",bitmap

In both cases, the color and screen data is incorrect. Bitmap is correct. The colors are switched as I described in the first comment (eg. $1 -> $b)

NOTE: If I start a MC bitmap image from scratch and draw and paint, !media, color pickers etc work correctly.

Update: Tested with .bmp and the same issue.

Something to test with.

• test.graphicscreen is drawn in C64studio and works correctly.
• test.png is a screen shot from VICE, cropped to 320x200
• test2.graphicscreen is import of test.png . The colors look fine, but running the code shows the colors incorrectly.

Thanks, I'm reading it, but this will take a bit to look into.

The import works in mysterious ways once it mixes the palette. As mentioned the image may look good, but !media data is weird. Anyway, I was able to convert my image with the 'Directly replace colors'. So my second issue is "sorted". The first one I still would like to have. ;-)

[GeorgRottensteiner]

Just in case/as a workaround, C64Studio may not always preserve the same bit pattern for a color between 8x8 blocks. You can force a certain bit pattern in the second tab.

I apologize for coming back to this only two years later.

Looks like you ran into an older bug of mine.
Test2.graphicscreen has a custom palette (which should not be allowed in C64 modes). So it looks correct in the editor but the indices are actually different. The green was set in palette index 1, light red in 2, etc. The export to binary/data assumes no such thing and converts the indices directly. Which of course ends up showing the wrong colors later on.

The issue auto-fixes itself kinda by re-importing the image with one of the newer versions.

And just by verifying the other listed issues I found a bunch of bugs.

Added these fixes:

• Multicolor bitmap import now sets the background color field. The multicolor combos are now not shown at all. The controls show the values for checking, not the ones chosen for the selected block.
• Crash when having multi color >= 8 and switching to VIC20 modes

I noticed the color selector is not updated to use the proper control for the selected mode as well (it's always listing the same 16 colors currently). Will be added tomorrow.
