Graphicscreen editor to show which colors are active in current charblock

[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.

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.

!media   "test2.graphicscreen",bitmap

         *= $0801

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. ;-)
