How to create your own Startup/Off-Logo

Required Software:
Irfanview ( http://irfanview.tuwien.ac.at/iview425_setup.exe )

1) Open the picture you like to convert with IrfanView
2) Do "Image->Resize/Resample" set the values like there is no bigger than 800
** to fit the picture to the screen you should turn picture to get 600x800 resolution, turn the picture with the keys "L" and "R"
3) Do "Image->Convert to Greyscale"
4) Press "I" and change the dpi to "96x96" (important to see full 16greyscale colors on PB!)
5) Press "S" and choose "Fileformat" BMP, save it any location you like
6) Transfer the created file to "/system/logo" on your Pocketbook
7) Choose your logo at the Settings
8) Enjoy

Actually, you don't need a special software for that, you can resize your favorite pics with the help of any graphics editor (Photoshop, etc). Though, thanks anyway for this program

Yes of course there is no special software needed, but i wanted to show a tutorial with a specific program. So I could create a step-by-step tutorial which will fit for everyone

You can use any program to convert your pictures. The Logos you add have to have following specifications:
* Fileformat: bmp
* Resultion: max 600x800 (for best fit-to-page use 1:3 not 800x600 which would be 3:1)
* max 8bit colordepth (2,4,8 fits)
* max 100x100 dpi

Irfanview is a nice piece of freeware. I've used it for the last ten years. Not fancy, but is quick and gets the job done.
Thanks for the tutorial!

Is there any reason why I keep seeing the last set logo on start-up even though I set the boot logo to current page?

I guess its because the startup logo doesnt make any sense to setup to last page because he will boot anyway and reload. Perhaps this funtions removal has been forgotten.

Does it work as log-off setting?
Does more sense to me, because you can set up to load last page at startup anyway.

// Edit:
This "bug" should only apper, if the last file was a pdf.

It's probably the same issue I had with the previous firmware version (101.14.1). I had to set the boot logo I wanted twice before the device would actually show the logo I wanted. So I would have to go to settings, appearance, etc. and set it, then exit the settings menu. And then do the same thing again.
Hope it helps.

I don't know exactly what I did, but it is functioning fine again (a little erratic behavior from the PB 360), ie no more boot logo on startup. Using FW 14.2. I also set to no boot logo on shut down.

First try to reset all logos to none and restart (Power off/on) the Pocketbook.
If this does not solve the problem, try to set it to a default logo (e.g. Bookland) and reboot the Pocketbook.

If this both doesnt fit the problem, push the reset button (On the back of your pocketbook beside the battery) for a short time, i dunno why this is fixing such probs but at me it did work.

If this all doesnt fit the problem, you should do a hard reset.

As to the Irfanview tutorial specifically: I'd add that you might as well "decrease color depth" as well (or do that together with grayscaling). By decreasing it to 16 colors, I reduced the file size from over 1 Mb to less than 250 kb. With no damage to the picture quality (for these purposes) that I could see.

I like to put a lot of different logos in there and let the software choose one at random for closing off and starting up. Would there be a firmware limit tot the amount of files you should put in there?

My experience is, that if you have more than 90 logos, you cant choose the ones over 90 by hand, but if you choose a random logo at startup, every logo will be shown.

One trick.
If you have, for example, 3 custom logos and you select random, then one of four logos you will see will be a Bookland logo. I have nothing against Bookland, I even like their logo ;-) , but I do not want them their logo instead of one of my converted Escher graphics.

The remedy is simple. Name one of your logos bookland.bmp


By the way, I have used gimp to scale and/or crop the images to 800x600 or 600x800 size and then I have used Linux commandline binary 'convert' from imagemagick package.
I have cropped and/or scaled pictures manually, because the raw pictures were very different and each of them required different manipulation.

This is an example of how to use the convert binary to produce working bmp file.
convert escher01.png -quantize GRAY +dither -colors 16 -rotate "-90>" escher01.bmp

the -rotate "-90>" is an interesting option, because it rotates the picture only if the width is greater than height.
There is also windows binary of imagemagick available. Imagemagick is the most powerful conversion software for bitmaps you can get. Just have a peek at the options http://www.imagemagick.org/script/convert.php


By the way, Ulli, bmp format does not store the resolution info, so you can set any resolution you want, as long as the picture is 600x800pixels. 600x800 pixels is the screen size.

You can take any image from 600x800, or rotate an image of 800x600 (as it is a usual size for wallpapers, that can be even better). And you don't need to have Photoshop or the like. You take the image, open it with paint, save it as "BMP, 256 colors) and you're set.

Lazy as I am, I've just googled some 600x800 images on Google (you can set an exact size for your pics in "advanced search"), edited them the way I said and that was it. I doubt to put them 'ere, as it's hard for me to credit them correctly.

This detail is buried in kacir's post above but I glossed over it repeatedly. After messing around with images in gimp for the last couple of months trying to make my own boot logos, I finally got the missing piece figured out: you need to use color-indexed bmp files.

In image magick, do 'convert FILENAME.bmp -colors 256 FILENAME.bmp' for each image using RGB space. In gimp, goto Image > Mode > Indexed (256) to do the same thing. I haven't tried 4 or 16 color indexes, as the working files I was looking at for comparison use 256 colors in their indexes. Also, I haven't tried saving from gimp to 16bit bmp.

I've been working with photos scanned from magazines as my source. This workflow I've developed allows me to keep the contrast of the image, retaining contrast and highlights, without losing as much detail as I would if I did a commandline conversion.
1) Crop original image to center the subject
2) Image > Scale [600x800 / 96x96 resolution, you may need to play with (un)locking x and y operations. Also, you can use the Scale tool to scale the selection in a single direction]
3) select the part of the newly scaled image I want to use via Path tool
4) copy selection to a new transparent layer
5) Image > Mode > Grayscale
6) Colors > levels [adjust so the black is just inside the left tail of the histogram, white is just inside the right tail of the histogram, and adjust grey to the middle of the "hump" in the histogram]. This requires some eyeballing and aesthetic jugement.
7) Create a new layer underneath the selection, either white or black depending on the dominant color of the selection
8) Merge selection and solid layer you just created
9) Colors > posterize [4]
10) Colors > levels [fine tune the pointers to bring back any details you may have lost]
11) Image > Mode > Indexed [256]
12) Save As > FILENAME.bmp [24bit]
