256x256 SCR file sample

[Dec]

I want to add to my own BMP2SCR tool a possibility of creation of Sinclair QL SCR files. I already know structure of SCR file, used color and so on. All I need now is sample of 256x256 SCR file and the same image in bmp/png/gif format (or just a photo of monitor). Could somebody provide me such sample?

A scr created by me for The King. In the zip file you will find the jpg, png, photoshop raw and QL scr files.
Keep in mind that the image was created using the Sinclair 8 colors palette. For images created with 8,16 or 32 bit palettes you will need to map the colors to the nearest QL color and probably use dither.

This is how my tool works:

In your sample scr file has additional header. I know nothing about this header but if you want the tool to create files with such header - give me some link to header description.

Just ignore the header. It was added by Qemulator, when I created the scr file in a DOS directory. I forgot to remove it.

Oooh, that's brilliant. Must give that a try.

QL SCR files normally don't have headers. PIC file do and the image data is the same for modes 4 & 8.
PIC files have a 10 byte header but need QPTR or EasPTR tools to display. You can also cut this header first and treat them as screens.
See this link about the header:

See this link about the header

Thanks. Your link contains short info about mode 16, mode 32, mode 33 and mode 64. Where can I get more info about this modes?

There is some in the SuperBASIC Manual. Check out the Display appendix. There is more information scattered about (eg in the SMSQ/E sources documentation.) But concise, ready-to-use information in one place is, to my knowledge, absent.
