Help With Poor Quality Photo





Hi Support

Today I bought a photo which I want to print to a canvas 120x90mm. Unfortunately, the quality of the photo is too poor, even though it is sold as XL 300dpi. The download is File: #171347227. The file is no good to me now.

Kind regards

Henriette
The file looks to be fine. It's 4500 X 300 pixels and the quality looks decent. 

The size probably that you're trying to print is quite large and you'll be requiring a larger file to avoid pixelation. 

I'd suggest you probably check with your printer the minimum file size required to print such a canvas and then license a file accordingly.

根據客人提供的圖片和信息確定為led原材料不良
已向供應商反應此問題，供應商已進行部份製程改善，目前對於光衰試驗尚在測試中，預計下週寄回本公司，本公司將會再次進行試驗確認，確保品質改善效果 

severe light-decay

according to te picture provided by the clients, it is confirmed that there are defects of the led raw materials. we've raised the claim to the 
supplier and the supplier is now in the process to improve the 
manufacturing process. 

currently they are generating the test of light-decay. we estimate that 
the result will be sent back to us by next week. our company will 
re-confirm the testing result to ensure the quality improvement. okay, from an iphone i see the problem. make sure you don’t have anything on too high of a pixel measurement regarding width as well as make sure none of what you have on position other than auto is sticking out. hope this helps. :wink::+1: here is a good system, camera plus lens: http://www.bhphotovideo.com/c/product/767600-reg/nikon\_d3100\_digital\_slr\_camera.html

please be aware that in some cases prices for cameras are prices for body only; the lens is extra.

and, stay away from the 'grey market' products. see the attached file: [extractnumberregex.xaml](/uploads/short-url/qbznpruo2eviur9srhj8qzzs7yn.xaml) (5.1 kb)

[image] Download and install the 64-bit driver for the printer. If this is an old printer, check with the manufacturer to see if they have a 64-bit driver. hey,

there might be not enough power for your usb devices after you draw some with your ffc camera.

what are you powering the board with? try dc jack with a beefier power supply.

cheers,

olex hi , i try it with this scenario, it work.

test code:

ov1 = overlay(’/home/xilinx/haddsub/prio.bit’)

pr=ov1.pr\_decoupler\_0

pr.write(0x0, 0) <- default set to zero

// before download partial bitstream set to one

pr.write(0x0, 1)

add\_pb=bitstream(’/home/xilinx/haddsub/pr\_0\_sub.bit’, n… seek and tell are still required.
