Design

• make “stamps” that say things like “only 20eur”, “fully co2 compensated”, “YOU MADE IT” “new artwork every friday”. randomize. them?

• gold buttons?

• a 3d model of a tee flying? maybe a video? probably hard to be good enough, consider other things, and consider funct. first

• multiple designs/fronts

Image sizes

• Dalle produces 1024x1024px

• 300 dpi is recommended
• 1024 px in 300 dpi is 8.7cm

• Recommended size for GIL-5000 is 4677x5881px (200dpi)

• circa 23x23cm seems right
• that’s 2717x2717px

• superresolution from deepai produces 3200px

• prodigi doesn’t seem to allow defining size
• definitely need to ask
• maybe there’s a way around it by using PNG?
• maybe it’s enough to use fit-in on an upscaled image? default is default for a reason

• seems like when a big picture is sent, tele makes 3-size versions, and all of them will be too small to put on a t-shirt
JSON for a big photo send as photo
JSON for a big photo sent as a file

Prodigi products:

• Hoodie: GLOBAL-HOOD-AWD-JH001 , 18eur

• T-shirt: GLOBAL-TEE-GIL-5000, 8gbp

Questions for Prodigi:

• (there was more on a piece of paper)

• what’s the difference between 5000 and 5000.0 in API for GLOBAL-TEE-GIL-5000?
code

• what’s taking so long with samples? are products gonna take long?

• important: can you define size of print? can you wrap in transparency if you have to?

• is there a way to override rotation? does fitPrintArea override it?

• is there a way to get a preview?

Implementation log

• connecting bot to Prodigi

• stuggling to get image size(s) from within Deno, ended up making a Lambda function

Decision record and nav log

• dalle to thshirt: first idea

• anything to tshirt on telegram easily - second idea

• also a web client maybe?

• prodigi is awesome for fulfilment, probably just disregard other options

• needed to figure out sizing

• ready to use the API, but have a big problem with sizing the image

• leaving the orders/sizing problems for now, and just trying grammy, trying to get to payment flow

• grammy is great (and deno and ts). got menu + payment flow to work

• grammy bot works, payment hooked up, info is there

• need bot hosting and to pass info onto pwinty/ew. amazon

• checking why I rejected Amazon, on Kisiel’s suggestion → they rejected me (14 days)

• deno deployment goes to sleep; asked for help and considering cloudflare instead

Docs
