If Launchpad is different here, this is worth studying. But it seems to me to be a PE feature. In principle the window's left-top is fixed, when resized to maximum the Wman will place the window in the right-bottom and adjust the origin. Even a less then maximum window, when moved to the right-bottom corner may give this "pointer on the bar" reading problem. A work around could be to calculate the position with more margin, before calling MDRAW and not rely on Wman.

I have just produced a 1600x1200 sprite file with PNGCVT, without problems. This revealed a problem that I suspect is an EasyPTR or SMSQ/E bug.

Re: [Ql-Users] JPG question
As this was about jpg, Dilwyn did not mention his BMP program that also shows BMP files in a window, without distortion, but only 24 bits. Also does batch conversions. But only tested AFAIK with QPC2/QXL Mode 32 style screens. There is conversion code for Qx0 Mode 33 screen but I am not sure if it has ever been tested (no Q40 or Q60!) Well, I have no Qx0 either but have used your BMP to convert to m33 and my routine to do the same. Converting these to m32 gave the same result, so they must be ok, or both have identical bugs! Ha! I thought someone would have told me by now if they didn't work. But, knowing my luck, it will be "identical bugs" :-) As almost everything needs conversion to the native pic format, this pic can then be saved. PE screen save and restore functions in Easyptr all work with PIC files, so although they are large, it serves as a good base point to work from, then it is fairly easy to save as PIC or screen-bytes formats, even Goerge's PSA files for his apps. GD2 sprites can be quite large (not sure if there's a limit) - it makes sense to be able to save at least small pictures as sprites. So far I can only convert uncompressed images, RLE sprites are done by Wman2 and can then be pic'd from the the screen. I haven't looked at the RLE format much, but I think it's just simple run length encoded as the name implies. I'm sureit's documented in one of the GD2/WMAN2 documents on my website.

I am working on a tool to convert/show bmp (4 bit to 24 bit) as pic files in the current mode (16 to 33) in an EasyPTR window.

I did try to contact him about it without success. Dilwyn, you may remember explaining here how to show pictures in a EasyPTR window, back in 2009. That started this project. But I needed some pictures to show so conversion routines were added. As almost everything needs conversion to the native pic format, this pic can then be saved. So far I can only convert uncompressed images, RLE sprites are done by Wman2 and can then be pic'd from the the screen. Photon can be used to convert from Jpeg if you use a screen grabber to capture the displayed QL output picture from the screen. George's suggestion re making a keyword out of Photon executable using Turbo's Task Commander is a handy hint to bear in mind too.

I use BMPCVT in one project of mine, but BMP files are huge, what is inconvenient. Qptr and EasyPTR have commands to create psa/pic files in memory and show them in a window. Remember that pic files are uncompressed like most BMP files so can also be quite large. Some of the BMPCVT commands may produce distortion when BMP lines are padded with empty bytes.

Thanks for this information and also to Bob for his reply. I should have known about Photon because it is quite an old program that I have tried it in the past, but there are so many graphics formats and I had forgotten which was supported. The person in question is a skilled programmer, but very much a "loner" who is not always aware of developments in the QL community. His program is in a very early stage of development, but I have done some testing and it works with all JPGs I have tried, although some needed resizing. He is also trying to write a detailed graphics program for GD2 systems, and that is the reason he tackled the JPG problem, but at the moment I am not quite sure what he wants me to do with them, Best Wishes, Geoff ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
