I tried to convert CW200-16.pic into bmp and I see the following:

CW200-16.png

Is it correct image or something wrong with my algorithms?

That looks about right

Here are samples of this image in mode 16, 32, and 33 Trying to understand files encoding but without success. For example CW200-16.pic. There are 10 bytes of header and color data with 4 bits per sample. Theoretically there are should be 200x200/2 = 20000 bytes of color data but in fact there are ...

Hi Per, looks great. with all this talk about Mode 64, has this screen mode ever been actually displayed of is is it just figment of somones memory... Mode 64 PICs and sprites are alive and kicking, its just that there are no mode 64 displays in the QL world to do them justice. I therefore also did...

Thanks.

Now I am looking for samples for additional screen modes.

Here are samples of this image in mode 16, 32, and 33 There are toolkits on Knoware.no to convert screen data between the various GD2 colour formats

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 ...

Thanks Per, I'll try that shortly. But I've never needed it as I have loaded the boot file for EasyPtr4 and I've got EasyMenu open - that's the two lines from the boot file. However, after much wailing and gnashing of teeth, I think have the culprit. When I saved the menu, I clicked the '8' option ...

Thanks for publishing this information Per. I just updated the "article"! :o However, no need to trouble you with it again: I just cut some of the waffle and added the most informative bits from my clarification to Derek. So anyone whod like to support PACs (and/or any of the rest) can fi...

Norm, try loading ptrmen_cde instead of easybmen_cde

Hi Derek, Thank you! The PAC file format is very similar to the standard QL PIC file format. The only differences are the "RLEx" long word tag prepended to the header and the fact that the graphics data following the header is RLE compressed, using the identical method as used for Wman2 sp...

So heres the latest from Knoware.no : 2020/12/14 Additions and Updates Added Snip - a screen snipper. Added Pic2Pac, to compress PICs to the new PAC format. Added Pac2Pic, to decompress the new format PACs to standard PICs. Added Pic2Spr, to convert PICs to compressed or uncomressed solid sprites. A...
