Every source i look says that i need to set the flag "SDL2_IMAGE_FORMATS=['png']", but when I run it, it gives me this error:
emcc: error: "SDL2_IMAGE_FORMATS=['png']": No such file or directory (""SDL2_IMAGE_FORMATS=['png']"" was expected to be an input file, based on the commandline arguments provided)
I even tried compiling PolyMars SDL Game using the instructions in the readme, but ended up with the same error.
Firefox 77.0beta supports displaying images in the the AV1 Image File Format, better know as AVIF.
Experimental AVIF support can be enabled in about:config by setting image.avif.enabled to true.

AVIF images will be displayed just as any other image file format. You can view and download some test images from av1-avif/testFiles

Experimental support for AVIF was merged with this commit. Currently there are still some limitations:
>There are many limitations currently, but this prototype should successfully render most basic AVIF images. Known limitations:
>
>- No support for any derived image items (crop, rotate, etc.)
>
>- No support for alpha planes
>
>- No support for ICC profiles (bug 1634741)
>
>- The primary image item must be an av01 (no grid support)
>
>- HDR images aren't tone-mapped
And there are still a few bugs open.

I've been scanning in a bunch of old computer & electronics magazines and want to upload them to the Internet Archive so others can enjoy them too.
Right now they're taking up about 3TB as uncompressed 600dpi TIFF files (1 page, one TIFF file, so each mag is like 80-200 TIFF files) on my Linux server and I'm unsure of the best way to submit them to IA for posterity.
I can convert them to any format, but I'm not sure what best practice is here - my gut tells me make each magazine PDF/A-2a with images embedded as lossless JPEG2000 files, but is that a waste of time considering IA does its own stuff to the images/PDFs?
How would I go around converting the rendering from an openGL GLCanvas object to a visual file format? To clarify, my intention to do the rendering on a headless server (by means of servlet) (I've already tested this part, and it works), and then convert the rendering, and send it over to the client through a html document. Should I do this by creating a still GLCanvas and rendering each frame individually?
Help would be appreciated. Incase you need it (I doubt you do) here's my the GLCanvas class.
Sorry for the confusing title.
I bought an SSD (1 TB) and the store loaded all my previous data onto it exactly as it was before (on the 1 TB HDD), so I took the laptop and didn't have to reinstall anything or anything like that.
I have noticed a big increase decrease in boot times but haven't noticed any improvements other than that, especially in music production (which I mostly care about).
Do I have to format the drive and reinstall Windows and everything to see the difference?
Edit: Booting became faster, not slower.
Personally I just do 1280x720 as a .png seeing as 1920x1080 apparently is too large, I'm only recently partnered though so to be fair I could very well be missing a trick, was curious to see what image sizes you guys used!

I assume it has to do with what's in the picture (e.g. something simple vs. something complex and visually busy), but I'm not really sure.
I have a design for a wall on a trade show booth. The Printer has recommended the full size print to be 150 dpi. Therefore, I have created a 1:10 scale with the image set at 1500dpi. I have chosen no compression in my pdf settings in order to retain the 1500 dpi upon export. The printer is now complaining about the file size. I understand that a 2 GB file is huge, but what else am I to do?
I have created an image in 'SVG' format in Inkscape which I now want to print on a heavy stock gloss paper. The image is a scale for use with an analog meter in a radio. The original plan called for creating the scale, print it on stock 20 lb office paper to proof the image and then using HP Photo paper, print the scale on a smooth glossy hard surface. The print out was 'spot on' on the 20 lb paper. Screen dimensioning matched the print outs. Then when trying to print on the photo paper the HP 8600 refused to draft it through. As it turns out this is a problem with the HP8600 series printers. I tried the internet tricks but the printer simply gives up trying to pull image grade paper through.
No big deal, I turned to FedEx Printing. However in in trying to upload my 'SVG' format file it refused to allow online upload. It turns out that Fedex Printing does not offer printing service for 'SVG' file format. They do accept 'JPG' and various Microsoft Word and Excel file formats as well as 'PDF's. So I saved my SVG product as a PDF and zipped off the image to Fedex Printing.
I failed however to proof print the image when printed as a PDF on my local printer. And upon pickup at Fedex while all looked honky-dory, upon cutting out the scale for application it became obvious something went awry with going to PDF. Closer inspection revealed the PDF printed file was about 8% less in width and height than the similarly printed 'SVG' format file. All primed to let Fedex hold it with both barrels, I opened Adobe Reader and printed the PDF on my home printer. Sure enough it was about 8% less in width and height then the similarly home printed SVG file format.
Questions:
- Is the observed shrinkage a known issue and I just happened to stumble into it?
- If this is expected is there a known percentage adjustment value to tell the printer to adjust his printer too so the desired final product dimension will be the desired result?
- Is a plan in motion to add saving as a JPEG in Inkscape's future?
Thanks

So I have a project where I am trying to build a program to compare images in a directory to see if there are duplicates. The problem is I tried reading the files in BGR mode and if the images are exactly the same but in different formats, the values are different. What is a more reliable way of comparing if images are the same between different formats? A certain channel or techniques?
I am using c++ for this project.
Thank you
So, for FluxEngine, my tool for reading vintage floppy disks and turning them into image files (<plug> http://cowlark.com/fluxengine/ </plug>), I am currently generating classic array-of-sector images, the kind of thing you get if you just dd off a block device. This is for decoded data, not nibble or flux data.
This works fine for most purposes but falls down when dealing with disk formats that don't have the same number of sectors per track (C64, Macintosh, many CP/M systems), and also when a disk fails to read correctly and has bad sectors. I've just had a feature request from someone who quite reasonably reckons that it would be nice to be able to tell which sectors are valid and which aren't.
So, I need some kind of structured disk image format. I could go and invent my own, but nobody would understand it and there are too many image file formats anyway. I've looked at the existing ones and there are a bewildering array of different formats, nearly all of them painfully obsolete and/or weird.
Does anyone know of a good, flexible, disk image format which I can look at?
